1) The researchers analyzed the data they collected as though it were at what level of measurement? a) Nominal b) Ordinal c) Interval/ration d) Experimental The correct answer is: d)experimental. 2) What was the mean post test empowerment score for the control group? Answer: 97.12 3) Compare the mean baseline post test depression scores of the experimental group. Was this an expected findings? Provide a rational for your answer? Answer: The baseline score of the experimental group is 14.00. According to the data provided in exercises 16, the depression decreased to 13.36 after the empowerment program. This is a positive result, which shows slight improvement (0.64). 4) Compare the mean baseline and posttest depression scores of the control group. Do these scores strengthen or weaken validity of the research results? Provide a rationale for your answer? Answer: The mean baseline depression scores of control group is 10.40. The mean post test depression scores of control group 10.40. Because the scores remains same
STATISTICS. EXERCISE 16 at the baseline level and post test level of depression rate of control group is neither weaken or strengthen with empowerment program, which shows no improvement with the program but also their depression score doesn’t increase. 5) Which group’s test scores had the least amount of variability or dispersion? Provide a rationale for your answer? Answer: The control group’s test scores had the least amount of variability or dispersion. The scores of SD base line and post tests of control group slightly different than experiment group. For example, control group empowerment SD difference 8.99 – 8.73 = 0.26; self
