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

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

Questions to be Graded 1. What 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

EXERCISE 29 Questions to be Graded 1. Were the groups in this study independent or dependent? Provide a rationale for your answer. The two groups were independent since they were formed based on gender with no intent to match subjects on any variable. The men and women selected didn’t share any relationship or live in the same location. 2. t = −3.15 describes the difference between women and men for what variable in this study? Is this value significant? Provide a rationale for your answer

in that as the independent variable of postnatal age increases the corresponding dependent variable increases. 2. The independent and dependent variables in Figure 3 are the same as in Figure 2‚ as well as the relationship between the variable. The difference is that figure 3 displays the relationship with regard to infants with a body weight of 1001-1500 grams‚ and figure 2 deals with infants with a body weight equal to or lesser than 1000. 3.
