1. The researchers analyzed the data they collected as though it were at what level of measurement? The answer is C‚ which is interval/ratio scale. 2. What was the mean posttest empowerment score for the control group? The mean posttest empowerment score for the control group was 97.12 3. Compare the mean baseline and posttest depression scores of the experimental group. Was this an expected finding? Provide a rationale for your answer. The data shows that there was an improvement in the mean

Sohal‚ S 04/05/11 (HLT-362 V) Applied Statistics for Healthcare Professionals Exercise 18 Q1. Assuming that the distribution is normal for weight relative to the ideal and 99% of the male participants scored between ( - 53.68‚ 64.64)‚where did 95% of the values for weight relative to the ideal lie? Round your answer to two decimal places. Answer: Mean of weight relative to ideal = 5.48 and Standard Deviation (σ) = 22.93. Calculation: (x bar) 1.96(σ) 5.48± 1.96(22.93) 5.48 - 1.96(22.93)

EXERCISE 11 1. What demographic variables were measured at least at the interval level of measurement? Age (yrs)‚ Income (annual)($)‚ Length of labor (hrs)‚ Return to work (wks)‚ and Number of hours working per week were measured at least at the interval level of measurement 2. What statistics were used to describe the length of labor in this study? Were these appropriate? The variable length of labor were used to describe by ratio data that can be described by using mean‚ range‚ and standard

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

EXERCISE 36 6. Can ANOVA be used to test proposed relationships or predicted correlations between variables in a single group? Provide rationale for your answer. ANOVA cannot be used to test proposed relationships or predicted correlations between variables in a single group because it is designed to test for correlations and interactions amongst groups‚ i.e. in the test group of patients with OA you are testing the correlations between those who do not use GI and PMR and those that do. Although

Exercise 11 Questions to be graded March 16‚ 2014 1. What demographic variables were measured at least at the interval level of measurements? Age‚ income‚ length of labor‚ return to work‚ and number of hours working per week 2. What statistics were used to describe the length of labor in the study? Were these appropriate? Mean and standard deviation were used to describe the length of labor. Yes‚ these were appropriate because a mean (M) can only be used to calculate on interval (and
