Test of Normality of Data in SPSS

In this video, I demonstrated how you can test whether your data is normally distributed or not using:
1. Shapiro-Wilk Test
2. Kolmogorov Smirnov Test
3. Histogram
4. Q-Q Plot
5. Skewness, and
6. Kurtosis
Your data is expected to be at least approximately normally distributed for your data to produce valid results for parametric tests, such as:
1. Pearson's Correlation
2. One Sample T-Test
3. Paired Sample T-Test
4. Analysis of Variance, and
5. Regression Analysis, among others.

So, to achieve these tests, the numerical and the graphical methods and approach were demonstrated and thereafter interpreted in great details for easy comprehension. The Skewness and Kurtosis as well as the Kolmogorov Smirnov test and the Shapiro-Wilk test constituted the numerical methods that were applied to test whether the data is approximately normally distributed or not. While on the other hand, the Histogram and the Q-Q plot were also engaged as the graphical methods. See the video to the end to learn about the "How".

From the two approaches, you can make a choice of the knowledge to utilize. All the individual methods spoken about are reliable, but you have the prerogative to use all simultaneously or use the one that is most suitable to you.

I'm doing an assignment and was trying to figure out whether my histogram showed a normal distribution or not, that line curve's helped. Thank you

Thank you for your valuable guide. Please share a video how to run endogeneity test in SPSS for primary/cross sectional data.

Hello, this was really helpful. Could this method be used if there are more than 2 groups?

Hello sir, thank You very much these wonderful lessons about spss, I’m inquiring you also give us a lessons about Stata. Stata is more complicated than spss. Thank you I hope you will.
