Question:

SPSS Problem The majority of variables that social scientists study are not normally distributed. This doesn’t typically cause problems in analysis when the goal of a study is to calculate means and standard deviations as long as sample sizes are greater than about 50. However, when characterizing the distribution of scores in one sample, or in a complete population (if this information is available), a non-normal distribution can cause complications. We can illustrate this point by examining the distribution of age in the GSS10 data file. According to your answer in number one, what is the percentage of people in the sample that are 25 years or less by taking your Z sore and finding the corresponding percentage in appendix B of your textbook. The percentage of people age 25 years or less is %. Please round to a whole number. Use the frequencies procedure to construct a tale of the percentage of cases at each value of AGE. What percentage of people in the sample are 25 years old or less?
