Can I ask a question about normal distribution as part of the assumptions in ANOVA please? Are we looking at normal distribution for the whole set of data or for each independent variable group? Say we're doing a one way ANOVA without repeated measures and we have 3 groups (A, B, C) who had one dependent variable measure (weight). Should we run normality test for each of A, B, and C ? Thank you

Instead of obtained score can normal distribution test be applied on likert response?

What is the degree of freedom in Shapiro-Wilk test ?

@datatab 9 ай бұрын

Hi the concept of "degrees of freedom" as commonly discussed in statistics (e.g., in the context of a t-test or chi-squared test) isn't directly applicable to the Shapiro-Wilk test in the same way. The Shapiro-Wilk test doesn't yield a "degrees of freedom" value like some other statistical tests. Instead, the test involves computing the W statistic based on the observed data and expected values under a normal distribution. The critical value to which you compare the W statistic depends on the sample size, and tables or software often provide these critical values for various significance levels and sample sizes. Regards, Hannah

What to do when normality test is positive for one parameter and negative for other parameter .

@datatab 2 жыл бұрын

Then you look at the graphical solution and decide with best conscience. It is best if you also mention it in your research!

For data that is collected in a Likert Scale, won't the data always violate the normality assumption? Because, the likert scale takes discrete values.

@abdul_raheemshahzad3855 2 жыл бұрын

wow mam well explaniation about normalilty test, but I have question that for analitical method we have a threshold of 0.05 i.e if results are less than 0.05 we can say that data is not normal and vice versa, but for graphical method what if the data is near to normal distribnution, that when we can cofidently say that our data is normal or not. just like a fix threshold value of p in analytical method.
