Provide a rationale for your answer. t = 2.03* the smallest t ratio listed in Table 2. It indicates that the cholesterol level change was statistically significant from pretest to 3 months. It is greater than the given value of p<0.05 7. Why are the larger t ratios more likely to be statistically significant? They

Exercise 36 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1‚ 22) = 9.619‚ p = 0.005. Discuss each aspect of these results. The F-value is high enough at the 5% level of significance to suggest a significant difference between the control and treatment groups. The p-value 0.005 < 0.05 hence this suggests a rejection of the null hypothesis
Premium Statistical hypothesis testing Statistical significance Statistics
Researchers routinely choose an alpha level of 0.05 for testing their hypotheses. What are some experiments for which you might want a lower alpha level (e.g.‚ 0.01)? What are some situations in which you might accept a higher level (e.g.‚ 0.1)? EXERCISE 20 Questions to be Graded 1. Which patient scored the highest on the preoperative CVLT Acquisition? What was his or her T score? 2. Which patient scored the lowest on postoperative CVLT Retrieval? What was this patient’s T score? 3. Did the patient

Threesamma Joseph HLT-362V 9/7/2012 1. The answer is C‚ interval/ratio. The researchers analyzed the data as though it were interval/ratio level. They calculated the mean and standard deviation which is only appropriate for interval/ratio level data. 2. The mean post-test empowerment score for the control group is 97.12. This data is found explicitly in the chart of data given. 3. The baseline score mean is 14 and the post-test depression score mean is 13.36‚ meaning they were less depressed

are the two groups whose results are reflected by the t ratios in Tables 2 and 3? Answer: The two groups that are reflected by the t rations in table 2 and 3 are the Program effects of cardiovascular risk factors (Table 2) and program effect on Health behavior (Table 3). 2. Which t ratio in Table 2 represents the greatest relative or standardized difference between the pretest and 3 months outcomes? Is this t ratio statistically significant? Provide a rationale for your answer. Answer: The greatest

variability or dispersion‚ because after six weeks of program implementation‚ the mean remained 10.40 from baseline. The standard deviation was also the same 10.34 from baseline there was no standard deviation noted. 6. Did the empowerment variable or self-care self-efficacy variable demonstrate the greatest amount of dispersion? Provide rationale for your answer. The self-efficacy variable
