Donnelly provides an exercise in Chapter 2 (Question 2.10 on page 42) that is based on n = 125 observations of the daily ocean temperature in Hawaii, and the purpose of the question is to form a frequency distribution from the observed data. All of these observations were collected in one year – suppose we had n = 125 observations from last year and n = 125 observations from 1995, and we constructed separate frequency distributions from the data for each year. Also, suppose our summary statistic
