Assignment W1 Identifying Types of Scores 1. A physical education teacher has no equipment to measure the times of her students in the 100 yard dash. She needed a way to measure her students’ performances so she decided to assign them grades based upon the place or order of finish in the race. What type of score is this? Discuss a possible problem with assigning grades using place of finish. _______________________________________________________________________ _______________________________________________________________________ _____________________________ _______________________________________________________________________ ___________________________________________ 2. A fitness center manager received a request from his immediate supervisor for a list of salaries for all paid fitness center employees. Her purpose for asking for the list is to review staff salary equity in the department. What type of score is the salary measure? Is this an appropriate way for the supervisor to measure what she is attempting to measure? _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _ 3. In the same fitness center as in #2, the supervisor asked for a listing by sex (females and males) in addition to a listing by ethnicity (e.g., Black, Asian, White, Hispanic, Pacific Islander, or mixed race) in the department. What types of measures are these? _______________________________________________________________________ _______________________________________________________________________ ____________________________ 4. An exercise specialist asked his client to count the number of times her heart beats in one minute. He also asked them to measure the number of times per week they exercised. What types of measures are these? How did you know? 2
_______________________________________________________________________ _______________________________________________________________________ ___________________________ Assignment W2 Descriptive Measurement 1. Find: n, Σ X 2 , ( Σ X) 2 , for the following one minute sit-up scores. 30, 35, 32, 25, 20, 21, 19, 17, 24, 20, 21 2. The following scores were obtained on a measurement midterm exam: 85 81 91 82 77 65 88 89 89 67 86 84 85 90 80 88 83 93 95 96 92 99 84 84 87 86 94 85 98 70 72 69 75 76 90 75 71 78 78 79 81 88 87 a. Form a simple frequency distribution with the data. b. Graph the scores in intervals of 3 on the abscissa (x axis) and corresponding frequencies on the ordinate (y-axis). c. What type of curve do you see? d. Find the mode, median, and mean of the measurement midterm scores 3. Calculate the mode, median, and mean for the following exercise heart rate scores. 100 110 115 116 116 118 119 120 122 122 122 122 125 127 130 133 136 146 156 166 3

Assignment W3 Measures of Central Tendency and Measures of Variability 1. The following scores were obtained in a single testing of a one minute sit-up test. When plotted, the scores appeared to fall along a normal curve. Report the appropriate measure of central tendency and measure of variability for this set of scores. Write an interpretation for the results obtained. 22 24 26 27 27 29 30 30 31 32 33 34 34 34 35 37 38 39 39 40 41 42 43 45 48 2. These scores below represent the results of the measurement final examination. The teacher gave an extremely easy test and the scores fell along a negatively skewed curve. Report the appropriate measure of central tendency and measure of variability. Write an interpretation for the results obtained.
