23 Compute the relative frequency distribution for each Age Group in order to compare distributions by Age Group. The frequency distributions in #19 cannot be compared directly because the Age Group sizes are unequal. For each Age Group, divide count by column subtotal (not the grand total). If you do this correctly, the first column will have 84%, 10%, and 6%. Age Group Under 6 6 to 9 10 to 14 15 to 21 Over 21 Viewing Frequency Never Once More Than Once 24 Make a stacked bar chart of the relative viewing frequencies by Age Group in 20 a): Select cells C69:H72 above, Insert, Insert Column or Bar Chart, and 2D Column and Stacked. If your stacked bar chart is done correctly, it will match the following picture: Chart Title 120% 100% 80% 60% 40% 20% 0% Under 6 6t09 10 to 14 15 to 21 Over 21 Age Group Viewing Frequency More Than Once Viewing Frequency Once ■Viewing Frequency Never 25 Examine the stacked bar chart of the distribution by Age Groups. If the relative frequency distributions are similar or the same, then Age Group is no more than a label. If the distributions are different, then Age Group matters because it determines distribution. Are Age Groups similar or same, or are they different and Age Group matters?
