What are the two groups whose results are reflected by the t ratios in Tables 2 and 3?

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.

Which t ratio listed in Table 3 represents the smallest relative difference between the pretest and 3 months? Is this t ratio statistically significant? What does this result mean?

What are the assumptions for conducting a t-test for dependent groups in a study? Which of these assumptions do you think were met by this study?

Compare the 3 months and 6 months t ratios for the variable Exercise from Table 3. What is your conclusion about the long-term effect of the health-promotion intervention on Exercise in this study?

What is the smallest, significant t ratio listed in Table 2? Provide a rationale for your answer.

Why are the larger t ratios more likely to be statistically significant?

Did the health-promotion program have a statistically significant effect on Systolic blood pressure (BP) in this study? Provide a rationale for your answer.

Examine the means and standard deviations for Systolic BP at pretest, 3 months (completion of the treatment), and 6 months. What do these results indicate? Are these results clinically important? Provide a rationale for your answer.

Is this study design strong or weak? Provide a rationale for your answer.

Would you, as a health care provider, implement this intervention at your facility based on the Total Risk Score results? Provide a rationale for your answer.

HLT 362V Module 4 ANOVA Excel Worksheet

SYSTOLIC BLOOD PRESSURE IN DIFFERENT AGE GROUPS

The following table contains a random sample of 40 women partitioned into three groups:

Group 1: ages below 20

Group 2: ages 20 through 40

Group 3: ages over 40

The values in the table are the systolic blood pressure levels

The hypothesis test:

H0:u1=u2=u3

H1: at least one of the treatment means is different

Use the Excel Analysis ToolPak to create an Anova – Single Factor table. Is there sufficient evidence to support the claim that women in the different age categories have different mean blood pressure levels? Give reasons for your decision.
