A KINE 4220 experiment was done by randomly assigning third year kinesiology students to two groups. One group was asked to walk for half an hour three times a week, while the other group was to sit quietly reading a book for half an hour three times a week. At the end of a year the change in both groups' blood pressure was measured and compared. 3. In this study there: a. are 3 independent variables b. is one independent variable c. are two dependent variables d. None of the above are true 4. This is a good example of: a. correlational research I). developmental research c. descriptive research d. None of the above are true 5. What is a distinction between a population parameter and a sample statistic? a. A population parameter is only based on conceptual measurements, but a sample statistic is based on a combination of real and conceptual measurements. b. A sample statistic changes each time you try to measure it, but a population parameter remains xed. c. A population parameter changes each time you try to measure it, but a sample statistic remains xed across samples. d. The true value of a sample statistic can never be known but the true value of a population parameter can be known. e. None of the above represent the true distinction between the two concepts 6. Which one of the following variables is not categorical? a. Age of a person b. Grades on the exam (in percentages) c. Height d. None of the above represent a good example of categorical variable 7. A list of 5 pulse rates is: 70, 64, 80, 74, 92. What is the median for this list? a. 74 b. 76 c. 77 d. 80 e. none of the above
