USE THIS INFORMATION TO ANSWER THE FOLLOWING THREE QUESTIONS: It is necessary to use inferential statistics to test hypotheses.To do this,four steps need to be followed: 1.Create null and alternative hypotheses about a population; 2.Create the criterion for rejecting Ho; 3.Obtain a sample from the population and compute the test statistic; 4. Make a decision about the null hypothesis based on the test statistic.The goal in following these steps is to be able to reject the Ho, or the null hypothesis.The null hypothesis proclaims that there is no effect, no difference or no change happening with respect to some characteristic of the underlying population.By rejecting the statement that says that a "treatment" is ineffective,it supports the hypothesis or research question that suggests that the "treatment" will have an effect (like they want it to).

USE THIS INFORMATION TO ANSWER THE FOLLOWING THREE QUESTIONS:Reliability:There are three different tests of reliability: 1.test-retest2.internal consistency3.interrater-All three of these test the consistency (reliability) of measures. -Reliability is denoted using the "Pearson product-moment correlation coefficient". -Denoted on a scale ranging from 0.00 - +1.00 and 0.00 - -1.00 (negative 1)-Negative linear relationships=minus sign; positive linear relationships=plus sign. -The signs are seen in front of the correlation coefficient.
