Question

If the two samples are the same size, then the pooled variance will equal the average of the two sample variances. True False For an independent-measures t statistic, what is the effect of increasing the number of scores in the samples? Increase the likelihood of rejecting H_0 and increase measures of effect size Increase the likelihood of rejecting H_0 and decrease measures of effect size Increase the likelihood of rejecting H_0 and have little or no effect on measures of effect size Decrease the likelihood of rejecting H_0 and have little or no effect on measures of effect size The estimated standard error for the independent-measures t statistic provides a measure of how much difference should exist. on average, between two sample means when the null hypothesis is true.

Explanation / Answer

Answer to the question as follows:

When the above is done then it

- increases the likelihood of rejecting the null hypothesis and have little or no effect on measures of effect size
