If you are doing a t-test in SPSS and Levene’s test shows p < .05 but the variances are: 20 for group 1 and 15 for group 2, then ______________
you can NOT assume you meet the assumptions of the t-test: the variances are not equivalent.
you can assume you meet the assumptions of the t-test: the variances are equivalent, or close enough.
you can assume you meet the assumptions of the t-test: the group means are far enough apart.
you can NOT assume you meet the assumptions of the t-test: the group means are too close together.
Homework Answers
The hypothesis of levene's test is
H0: we assume two samples are equal variance
H1: we assume two samples are different variance
Here p< 0. 05, we reject H0.
That means the variance are different. We assume two samples have different variance.. Optionb3

Important instructions: For all situations requiring a hypothesis test (z test, one-sample t test, one-sample variance test or two-sample t test), you must 1. Choose the appropriate test based on the information you are given 2. State null and alternative hypotheses 3. Choose a one or two tailed test and explain why you chose that test 4. Calculate the appropriate test statistic, showing all work neatly. This includes calculations of means, standard deviations, etc. 5. Draw the appropriate conclusions (i.e.,...
