Non-normality of the dependent variable can cause non-normality of residuals in ANOV...

for testing if 3(+) population means are all equal. The two simplest scenarios are one-way ANOVA for comparing 3(+) groups on 1 variable: do all children from school A, B and C have equal mean IQ scores? * repeated measures ANOVA for comparing 3(+) variables in 1 group: is the ...

This will give us the p value, which, in this case, is 0.03: This appears to be small, so we're going to reject the null hypothesis that all processes yield resistors with the same level of resistance. It appears at least one of them has a different mean level of resistance. This...
estimation, hypothesis testing, model selection, residual analysis and diagnostics. Explain your findings in a 3 to 4- page report. Your report may include the following sections: • Introduction: Statement of the problem. • Material and Methods: Description of the data and methods that you ...
We'll first just inspect the mean ratings in our sample. We'll then try and generalize this sample outcome to our population by testing the null hypothesis that the 4 population mean scores are all equal. We'll reject this if our sample means are very different. Reversely, our sample mean...
