Question

1) If an independent measures t statistic has df = 20, then there were 21 individuals participating in the research study. TRUE OR FALSE?

2) The homogeneity of variances assumption states that the two population variances are unequal. TRUE OR FALSE?

3) If both samples have the same number of scores (n), then the independent measures t statistic will have df = n1 + n2 - 2. TRUE OR FALSE?

4) If two samples are the same size, then the pooled variances will equal the average of the two sample variances. TRUE OR FALSE?

5) Two separate samples, each with n = 20 scores, will produce an independent measures t statistic with df = 38. TRUE OR FALSE?

6) Heterogeneity of variance occurs when the groups have equal sample sizes and equal variances. TRUE OR FALSE?

7) When pooling variances, the resulting value will be closer to the variance for the sample with the smaller number of scores. TRUE OR FALSE?

8) The independent measures t test is used when two groups are compared. TRUE OR FALSE?

9) The null hypothesis for the independent measures t test states that there is no difference between the population means. TRUE OR FALSE?

1) If an independent measures t statistic has df = 20, then there were 21 individuals participating in the research study.

Answer is True as df=n-1

So n=df+1=20+1=21
