Dissertaton Consulting

Dissertations can sometimes be very complicated and the students may not always have access to the teachers for assistance relating to selecting a dissertation topic, conducting research, writing the dissertation or actual analysis of data. A large number of students prepare dissertations for the first time and often require help in gathering research materials as much as writing up the results. For many of these first-timers, a dissertation becomes a headache more than a valuable academic experience. A dissertation consultant can be the answer to many a students’ prayers.

A dissertation consultant is a professionally trained individual that provides useful direction to students in terms of selecting topics for dissertations, setting up experiments, designing research methodology and writing up the actual dissertation or proofreading it. A dissertation consultant is trained in all these topics, in addition to providing ad-hoc guidance for students when they need a lot more time than their advisor can provide. This does not necessarily mean that the dissertation consultant is replacing the advisor at the college, but rather that the dissertation consultant is acting as a supplement to the college advisor.

There is a popular notion that a dissertation consultant writes papers for students. The truth is that a good dissertation consultant provides writing guidance and advice to the students. In addition, the dissertation consultant can assist with proofreading or cleaning up the dissertation to make it look more professional. Often a student will write a half-decent proposal but when it comes to writing up results of a statistical analysis, the task is more difficult than expected.

In addition to writing assistance, a dissertation consultant can help research the topic in depth and provide support for the task of research as well. For instance, many students may not be very good at navigating complex research databases or citation formats. Not only can a dissertation consultant provide help on citation formats and other aspects of the writing, he or she can also help select the right format and template.

Dissertation consultant also enables students to manage their time more effectively while writing dissertations, because a lot of students have to juggle the demands of family obligations or a full time job while attending classes. A dissertation consultant helps the students set reasonable writing schedules and goals that can go a long way in making room for their non-student life demands, which are often more pressing.

The advantages of hiring an expert dissertation consultant are many. First of all, the students will get the qualitative and quantitative help they need. In addition, the dissertation consultant can provide real time support on what should and should not be included in the dissertation, thereby offering valuable and meaningful critique on the dissertation.

The students availing the services of dissertation consultant must make sure that their concerns and questions are addressed properly, to their satisfaction and understanding. For this purpose, they must enquire about the qualifications and experience of the dissertation consultant. Often, the best way to choose a dissertation consultant is by word of mouth- seeking references from fellow students or colleagues. However, even google can sometimes yield a very high quality consultant, although it’s best to communicate effectively with the dissertation consultant to make sure there is a good fit.

There must be a good work dynamic between the student and the dissertation consultant. If that does not happen then it will create friction between the two and ultimately it will affect the quality of the dissertation. Where there is proper and free communication between the dissertation consultant and the students, the results will correspondingly be of much higher quality. Students must always feel free to discuss new ideas with the dissertation consultant.

It’s important to think of the dissertation consultant as a mentor or guide rather than a vendor who provides academic assistance for a fee. The right dissertation consultant will provide an experience that lasts the student a lifetime, by teaching them to fish rather than giving them a fish to eat.

Range in Statistics, Variance in Statistics, Standard Deviation in Statistics, and Standard Error of the Mean in Statistics

I spoke with someone today about a few things that I just take for granted as a dissertation consultant and statistician. This particular client, ever so politely asked that I explain the terminology associated with her descriptive statistics. Specifically, the terms in question were range, variance, standard deviation, and standard deviation of the mean. There are so many terms out there like these that are thrown around in research papers, journal entries and the such, without many of the readers – or even the authors – really knowing what they mean. 

  • What exactly is range and how is it used in a dissertation or thesis?
  • What about variance and standard deviation? Are there numbers I should be looking for when I see the results of these tests?
  • What in the world is standard error and is there a difference between just standard error and standard error of the mean?

For me, and any other statistician, these questions are easy, but what about the nursing student trying to finish up nursing school or the school teacher trying to become an assistant principle or principle so he or she can shape the lives or our young people? These people don't really have to be experts on this stuff and will probably never use it again.

So it's my job to make sure I can help these wonderful people move on to the truly important things, like saving lives and teaching children. Since you don't have to be an expert and you really just want to know how and why you are presenting this information, here is a quick and dirty explanation of those terms I mentioned at the top.

What is range in statistics?

Also commonly called range score, statistics range, or range value (these aren't formal terms, just what they're commonly called by my clients), this is in the most simple terms, the difference between the largest and smallest values in variable in a dataset. To calculate this by hand…you guessed it…subtract the smallest value in the variable from the largest value in the variable. You shouldn't have to calculate this by hand, since Excel will do this for you and other statistics software packages like SPSS and SAS will also calculate range for, by simply checking a box or choosing a command. I would like to clarify before I continue that I specify variable, because the range measurement will only be for one variable in your dataset. Receive professional assistance with using range in your Master's thesis, Master's dissertation, Ph.D. thesis, or Ph.D. dissertation.   

What is variance in statistics?

Variance is used in so many ways that I could dedicate a blog just to variance as it pertains to statistics. What do you need to know to stand before your committee and defend this stuff? It pretty much tells you how the data is dispersed around the mean of your variable. If the variance is small, then the data is very closely dispersed around the mean, i.e. the data points are close in value to the mean. If the variance is large, then the data is more widely dispersed around the mean, i.e. the data points are different from the mean.

You would be crazy to calculate by hand since there are so many programs out there that will do it for you, but should you choose to, you are going to average the squared differences between each value in the variable and the mean. To illustrate more plainly, let's start with just one value. I am going to refer to the dataset 3, 5, 8, 4, 2, and 9.

  1. To start, we are going to calculate the mean of the dataset. We calculate the mean or average of the variable by adding the values and dividing by the number of values – just like grade school. When we finish we have an average or mean of 5.1667.
  2. We are then going to subtract that mean from the first value in the dataset, which is 3. This gives us -2.1667.
  3. We then square this value to obtain 4.6946 rounded.
  4. This value of 4.6946 is then divided by the number of observations or numbers in our variable minus 1, which is 0.9389.
  5. Do the same thing for each of the other variables in the variable, 5, 8, 4, 2, and 9.
  6. You should end up with 0.9389 + 0.0056 + 1.6055 + 0.2722 + 2.0056 + 2.9388 = 7.7666. This is our variance for the variable in our dataset consisting of 3, 5, 8, 4, 2, and 9.
Simple enough, and this number is really going to lay the groundwork for our other descriptive statistical measures, mainly standard deviation and standard error of the mean. Click here to receive help with using variance in your Master's thesis, Master's dissertation, Ph.D. thesis, or Ph.D. dissertation.

What is standard deviation in statistics?

Standard deviation in statistics is also presented in the descriptive statistics results of any graduate thesis or dissertation. For the purposes of what we are doing, the standard deviation tells us how all the observations in the variable are distributed or clustered about the mean of the variable. After calculating the variance, the rest is all downhill. You are going to love this! Ready? The standard deviation is simply the square root of the variance, which is 2.7869. That's it!

The same rules apply to standard deviation as apply to variance: when the data is very closely dispersed around the mean, i.e. the data points are close in value to the mean, the standard deviation will be small. When the data is more widely dispersed around the mean, i.e. the data points are different from the mean, the standard deviation will be large. To receive help calculating standard deviation for the variables used in your Master's thesis, Master's dissertation, Ph.D. thesis, or Ph.D. dissertation, click here.

What is standard error of the mean in statistics?

Standard error of the mean in statistics is often defined as the standard deviation of all possible sample means. Basically, if we had a population from which to draw, we could draw many 6 observation samples from our population and each of the samples could have a different mean. The standard error tells us how much these means vary. With one sample, we often still want to know how much the mean could vary, therefore we estimate the standard error by dividing the standard deviation we just calculated (2.7869) by the square root of the number of observations (6) in our variable. We end up with 1.1377. Another easy one.

Interpreting the estimated standard error of the mean is a little different. In this case, the number is going to fluctute with the number of observations we have in the variable. The more observations we have, the smaller the standard error. The fewer the observations, the larger the standard error. Click here to receive help with standard error as it pertains to the statistical analysis in your Master's thesis, Master's dissertation, Ph.D. thesis, or Ph.D. dissertation.

It is amazingly rewarding to help graduate students understand this stuff. It is the moment the light switch comes on that makes it all worthwhile.

Dissertation Statistics and Thesis Statistics

There are a dizzying number of statistical tests out there and knowing where to start can be a real problem. You probably haven't taken a statistics class in years and now you are being called upon to recall statistical tests and details that you believe even a statistician would not know. Fear not! Read on and click through to get all the help you need.

What are dissertation statistics and thesis statistics?

Dissertation statistics and thesis statistics are the statistics used in a dissertation or thesis… just kidding – okay seriously. You have spent all kinds of time on the internet and the library completing this epic task only to hit the wall of………statistics.

There are all kinds of statistics you could use for your Master's thesis, Master's dissertation, Ph.D. thesis, and Ph.D. dissertation. These days, it is assumed and maybe required that you use multivariate statistics of some kind. The days of simple bivariate correlations and t-tests seem to be gone forever – depending on the area of expertise. Given the increased level of familiarity with the tests like multiple regression, logistic regression, n-way ANOVA, mixed ANOVA, ANCOVA, MANOVA, MANCOVA, and the like, institutions and committee members' expectations for you thesis or dissertation are much higher. The individual tests, their benefits, and their uses are described in some more detail here.

What statistical analysis should I use for my thesis or dissertation?

The statistical analysis for your thesis or dissertation should be appropriate for what you are researching and should fit with your needs and capabilities. I know, that's not saying much, but it's important that you're comfortable with the statistical analysis you will be conducting. An experienced dissertation consultant will help you tremendously with this. You will find a great one here.

I am going to go briefly cover why multivariate analysis are so popular with institutions and committees, but before your head explodes, keep in mind that seeking professional help will simplify this greatly by saving you the hours of researching the tests and revising if – God forbid – the tests are run incorrectly. In the end, an experienced dissertation consultant is worth his weight in gold.

What are multivariate statistics and why should I use them for my dissertation or thesis?

The main thing multivariate statistics do is protect your alpha. Something happens when you conduct multiple tests on the same dataset, e.g. t-tests and correlations: you run the risk of the statistical tests being falsely significant simply because multiple tests were conducted on the dataset. In other words, your statistical tests may show significance even though they aren't.

There are corrections for this like the Bonferroni correction, however, a researcher can avoid the stringent thresholds that follow with implementation of the Bonferroni correction by simply conducting multivariate statistics for their dissertation or thesis. Instead of conducting multiple tests on the same dataset, maybe only one or two tests are conducted. Get help using multivariate statistics with your Master's thesis, Master's dissertation, Ph.D. thesis, or Ph.D. dissertation.

Your dissertation topic should be something reasonable that is not going to take a lifetime to finish, but still be of practical importance to at least the people in your field of study.

· Write about something people care about or will care about in a couple years. This is probably going to take you some time, so some foresight is necessary. This will also help get your dissertation published and help get you the notoriety your want.

· Choose a dissertation topic with available information to research, but not so much that you don’t know where to begin. Be somewhat specific.

· Choose a dissertation topic that other researchers have used before. This will simplify the rest of your dissertation process, since you will have an idea of the statistical analysis you will use and the results you will get.

· Visit our site for links, books, and more advice on choosing your Master's or Ph.D. dissertation topic.

How do I write the Dissertation Proposal?

As you know, the dissertation proposal has several components. The dissertation proposal includes, at a minimum, the participants, instruments, procedure, data analysis plan and sample size justification.

The participants section is typically the first part of the dissertation proposal methodology. It describes who the participants are and lends itself to generalizing the findings to those type of participants (e.g., grade school children, individuals in southeast of the country, etc.).

The dissertation proposal has an instrument or materials section. Describing the instrument and the subscales are critical in the dissertation proposal. You should list the subscales, the items that comprise the subscales, and the reliability and validity of the scales.

The procedure section of the dissertation proposal describes the way you administer the instrument to the participants. It should be a step-by-step “how-to” in such detail that the reader could replicate the study.

The dissertation proposal should be clear and organized. At Statistics Solutions, we have assisted thousands of students with their dissertation proposal. If you have any dissertation proposal questions, feel free to contact Statistics Solutions for a free 30-min consult. Our phone number is (877) 437-8622 or email, us at: www.StatisticsSolutions.com.
