9. The numbers below are the number of aggres sive acts for each preschool child over a week in a class of 25 students. First, construct a fre- quency distribution in the manner of Table 2-9, including the real limits, size, and midpoints of the class intervals. For such a small distribu- tion only five or so intervals are necessary. Sec- ond, compose a relative frequency, cumulative frequency, and cumulative relative...
