uca.eduWhat we have in Figure 10.1 are two frequency distributions of yards per play. A frequency distribution shows the number of times each score (in this case, the number of yards) is obtained. We can tell at a glance that these two distributions are markedly different. A pass play is a study in contrasts; it leads to extremely variable outcomes.

ncert.nic.inIn this chapter , we shall extend the study of these three measures, i.e., mean, median and mode from ungrouped data to that of grouped data. We shall also discuss the concept of cumulative frequency, the cumulative frequency distribution and how to draw cumulative frequency curves, called ogives. 14.2 Mean of Grouped Data
