Question details

mulative frequcnc 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 frequency distribution for these data in the manner of Table 2-5. Third, construct polygons and his- tograms for the frequency and relative fre- quency distributions and a polygon for the two cumulative distributions. 40 28 39 34 41 35 36 47 47 37 43 38 42 37 27 38 37 32 40 48 26
