The very first thing you should do before performing any statistical test, is to see whether your data is normally distributed. Normality testing in SPSS will reveal more about the dataset and ultimately decide which statistical test you should perform. The first thing you will need is some data of course! I have created an example dataset that I will be using for this guide. It is simply a file containing two variables of ages in years and the sex of a population.

Why is it so difficult to write a thesis? Writing a thesis is like a mad dash to the finish of a long marathon: it adds luster to your well-deserved degree. In theory, at least. Because in practice, it turns out that a thesis is often a stumbling block to students. Why do students have such difficulties with the final thesis? Amos van Gelderen, language lecturer at the Rotterdam University of Applied Sciences, observes two things.
Normality Test of Kolmogorov-Smirnov Using SPSS
In statistics , normality tests are used to determine if a data set is well-modeled by a normal distribution and to compute how likely it is for a random variable underlying the data set to be normally distributed. More precisely, the tests are a form of model selection , and can be interpreted several ways, depending on one's interpretations of probability :. A normality test is used to determine whether sample data has been drawn from a normally distributed population within some tolerance. A number of statistical tests, such as the Student's t-test and the one-way and two-way ANOVA require a normally distributed sample population.
