So, in this question, we are asked to find the requirements to perform a one -way anova test.
00:22
Is the test robust? yes, it is a robust test and we need to select all the options that apply.
00:30
So, let's see the options.
00:33
A, the populations must have the same variance.
00:37
So, populations, same variance, that is each treatment group has population of variance sigma square.
00:51
This is true.
00:53
So, this is the requirement.
00:58
Next, the sample means must all be equal.
01:02
No, that is not a requirement.
01:05
The within sample variability must be less than the combined variances of each group, not a requirement.
01:14
There must be k simple random samples...
