The statistical tests that can answer your research questions



Dissertation statistical tests are a doctoral student's best friend! You may be skeptical but let me explain why. You can literally take an ocean of data and turn it into one number that answers your dissertation research questions.

Look at the data set below. It can make your head spin. What does it tell you? Not much….

If you have been given a massive assortment of numbers and have no hope of understanding them, although you have looked at them for hours, use statistics.

1. They summarize information and present it in a straightforward, compelling manner.

2. They tell us whether we did have an impact and it was worthwhile, so that we can take action.

3. They document relationships that are meaningful so that we can take action.

Life will be simple. How great is that?

Quantitative and qualitative data make up your database. This is the core from which statistics will be generated. There are many types to choose from:

Descriptive Statistics (Mean, Median and Mode)

T-test

ANOVA

Chi Square

Correlation

Scattergram

Multiple Regression
