11. The effect of transformations of scale on the mean and standard deviation You just completed a small research project for your psychology class concerning the effects of an event that happened two years ago on women’s opinions and actions today. The mean age of participants in your study is 19.2 years with a standard deviation of 2.1 years. As you write up your results, you realize that what matters is the ages of the participants two years ago when the event happened, not their ages now. You decide to subtract 2 from each of your participants’ ages. After you subtract 2 years, the mean age in your sample is17.2 years. The new standard deviation of the ages in your sample is2.1 years. One of the variables you collected was the study participants’ weights in kilograms. The mean weight of participants in your study is 65.3 kilograms with a standard deviation of 7.836 kilograms. Your professor, however, requested that you report this value in pounds. To convert from kilograms to pounds, you multiply by 2.2. After you multiply the weights of your participants by 2.2, the mean weight in your sample is143.7 pounds. The new standard deviation of the weights in your sample is17.2 pounds.
