******************** Appendix F - Training Programs ******************** Appendix Six for A System Approach To Training by Donald Clark copyright 1995 http://www.nwlink.com/~donclark/hrd.html donclark@nwlink.com -------- Programmed Instruction for the Mean, Medium, and Mode -------- 1. Data, by itself, would be of little use to a researcher unless she had certain procedures for describing or analyzing it. A list of 1,000 test scores can be an overwhelming sight. 2. Procedures used to analyze data are called statistics. One important function of statistics is to provide useful information from the raw data. 3. Procedures used to extract information out of a large number of scores are called __________________. 4. A group of scores can be described in terms of some measure of central tendency. Measures of central tendency provide information about the typical or average score. statistics 5. Measures of central tendency are used to find the _________________ score. 6. There are three common ways to find a measure of central tendency. They are the mean, the medium, and the mode. typical or average 7. The average score in a distribution is found by using a measure of _____________ . 8. The mean is the most familiar to many people. It is often called the average, but its technical name is the mean. It is found by adding all scores and dividing the sum by the number of cases. central tendency 9. The medium is the middle-most score when all scores have been arranged in order of size. The medium is the point that bisects the distribution, half the cases falling above it and half below it. 10. The mode is the most frequent score. 11. The three most common ways of finding a measure of central tendency are the __________________, the __________________, and the __________________. 12. What is the medium in this distribution? 58 55 52 50 47 47 41 mean medium mode 13. What is the mode in the above distribution? 52 14. The mean is found by first adding up all the scores in the 47 distribution and then dividing the sum by the number of scores in the distribution. The computation for the above distribution is shown below. 58 + 55 + 50 + 52 + 47 + 47 + 41 = 350 First, add the scores together 350 / 7 = 50 Second, divide the total by the total number of scores The mean is 50 15. What is the mean for the following distribution? 25 25 15 15 10 16. The mean, medium, and mode provide a single, most typical 18 or representative score to characterize the performance of the entire group.
