Children in fear of TV cruelty


Several possibilities exist for using this article in the classroom. Students can discuss the graphical representations and how easy they are to interpret. Students should notice the different scales on the graphs and the possibility that this could be confusing for some.

The report is good in stating the sample size used for children and parents but perhaps could have been better in explaining how the samples were chosen. Given the results at the very end it would be useful to know if the parents surveyed were related to the children surveyed.

This article could also be used in a Media Studies class when policy and practice are being discussed.

For some results it would be possible to construct side-by-side bar graphs to compare boys to girls.

For advanced students it is possible to carry out z-tests for the difference in proportions of children and parents thinking children watched TV before school and during dinner. One expects the results to be statistically significant.

For example for television watching before school:
p1-hat = .53, p2-hat = .35, n1 = 1710, n2 = 517, p-hat (906+181)/(1710+517) = .49,
sp(D) = sqrt [(.49)(.51)(1/1710 + 1/517)]
= .025 and
z = (.53 - .35/.025 = 7.2
This is a very extreme value.
