. Hi this is Raj Kumar SubediIn this video I have quickly described the step of doing normality test using SPSS. This video shows how to test for normality with the Shapiro-Wilk test and several visuals to show if a dataset is normally distributed or not. For the approximately normally distributed data p 0582 so the null hypothesis is retainedat the 005 level of.
The data is normally distributed. One of the assumptions for most parametric tests to be reliable is that the data is approximately normally distributed. If data need to be approximately normally distributed this tutorial shows how to use SPSS to verify this.
A new window pops out. Value under the Shapiro-Wilk column is greater than 005 we can conclude that Int_Politics for this. Hypothesis test for a test of normality.
Failing the normality test allows you to state with 95 confidence the data does not fit the normal distribution. Click Analyze Click Descriptive Statistics Click Explore Place your dependent variables the ones you want to check for normality into the Dependent List box. Ignore the other options.
