Effect- difference between population means. Squared point biserial correlation

Question

Effect- difference between population means. Squared point biserial correlation -The population of variance in the explained by the independent variable Text Review Section I Two independent samples occur when (1) in one sample are not paired with observations in the other sample. When a t test is conducted for two independent samples, he difference between population means reflects the (2) example in the text, the variable is (3) When there is lnttle di the two population means, there is little effect of the variable being studied. In the The null hypothesis states there is (4) difference between population means. There ane ans does not three possible alternative hypotheses. One states that the difference between population me equal zero. This would represent a (5) that the difference is less than zero. This is a one-tailed test with the (6) third possibility is a one-tailed test with (7) between population means (8) particular direction, a (9) test. A second possible hypothesis states tail critical. The tail critical which states that the difference zero. When there is concern only about difference in a or one-tailed hypothesis test should be used. Just as the sampling distribution of the mean (presented in Chapter 13) is not actually constructed, the sampling distribution for the difference between sample means is not constructed. Instead, we rely on statistical theory to provide information about the mean and standard error for the s In the two-sample case, the sampling distribution of Xi-X2. In practice, there is only one observed difference and the (10 nducted to determine whether it qualifies as a common or rare outcome. In the one-sample case, the mean of the sampling distribution equals the mean of(1 mean of the sampling distribution equals the (12) between population means.
