Week Seven Homework Exercise Answer the following questions, covering material from Ch. 13 of Methods in Behavioral Research Define inferential statistics and how researchers use inferential statistics to draw conclusions from sample data. According to Cozby (2009) inferential statistics are used to determine whether we can in fact make statements that the results reflect what would happen if we were to conduct the experiment again and again with multiple samples Define probability and discuss how it relates to the concept of statistical significance. Probability is the possible that an outcome of an experience or an event will occur (Cozby 2009) Statistical significant and probability are one in the same. A researcher is studying the effects of yoga on depression. Participants are randomly assigned to one of two groups yoga and medication (experimental group) or support group and medication (control group). What is the null hypothesis What is the research hypothesisSince the experimental group differs from the control group this would be the research hypothesis and if there is no difference in the mean this would be the null hypothesis In the scenario described in the previous question, the researcher implements two programs simultaneously a 6-week yoga program coupled with medication management and a 6-week support group program coupled with medication management. At the end of the 6 weeks, participants complete a questionnaire measuring depression. The researcher compares the mean score of the experimental group with the mean score of the control group. What statistical test would be most appropriate for this purpose and why What is the role of probability in this statistical test Bivariate Research because in this case the researcher is studying whether two variables are related. The role of probability in this statistical test is to determine what outcome is likely to occur In the scenario described in the previous questions, the researcher predicted that
