# Consider the two graphs depicting the influence of advertisements on making large purchases for two different age

## Question:

Consider the two graphs depicting the influence of advertisements on making large purchases for two different age groups, those 18€“34 years old and those 45€“54 years old (based on a Harris Poll of about 2500 adults aged 18 or older). Note: Other responses such as €œnot sure€ and €œnot applicable€ were also possible.
Influence of Advertising on Most Recent Large Purchase

(a) Taking a quick glance at the graphs, Jenna thought that there was very little difference (maybe less than 1%) in the percentage of the two age groups who said that ads were influential. How would you change the graphs so that Jenna would not be misled so easily? Hint: Look at the vertical scales of the two graphs.
(b) Take the information from the two graphs and make a cluster bar graph showing the percentage by age group reporting to be influenced by ads and those reporting they were not influenced by ads.
