It is a statistical method used to assess whether there are any statistically significant differences between the means of three or more independent groups.

If t stat is greater than t crit, then we (a)   the null hypothesis.

It is a statistical test used to compare the means of two independent groups when the variances are equal.

(a)  

What should be used to test the homogeneity of the variances of two independent samples?

Pooled Variance is Population means from two unrelated groups are equal.

The pooled variance t-test is a non-parametric test.

The pooled variance t-test is used to compare the means of two independent, normally distributed populations.

In a pooled variance t-test, the null hypothesis is that the two means being compared are equal.

In a pooled variance t-test, the null hypothesis is that the two means being compared are equal.

In a pooled variance t-test, the critical value for a significance level of 0.05 is:
