QUESTION:

Problem 23E

The article “Statistical Modeling of the Time Course of Tantrum Anger” (Annals of Applied Stats, 2009: 1013–1034) discussed how anger intensity in children’s tantrums could be related to tantrum duration as well as behavioral indicators such as shouting, stamping, and pushing or pulling. The following frequency distribution was given (and also the corresponding histogram):

Draw the histogram and then comment on any interesting features.

Problem 23E

The article “Statistical Modeling of the Time Course of Tantrum Anger” (Annals of Applied Stats, 2009: 1013–1034) discussed how anger intensity in children’s tantrums could be related to tantrum duration as well as behavioral indicators such as shouting, stamping, and pushing or pulling. The following frequency distribution was given (and also the corresponding histogram):

Draw the histogram and then comment on any interesting features.

ANSWER:

Solution:

Step 1 of 2:

The frequency distribution of how anger intensity could be related to tantrum duration and other factors in children’s tantrum is given.

Class interval	Frequency
0-<2	136
2-<4	92
4-<11	71
11-<20	26
20-<30	7
30-<40	3

We have to draw the histogram of the data.
