Consider the survey question shown below. Thinking back to the commercial you just saw, how relevant or not relevant would you say the commercial's message was? Hould you say that it was ..
$\begin{array} { l l } \text { Extremely relevant } & \text { \_\_\_\_(1) } \ \text { Somewhat relevant } & \text { \_\_\_\_(2) } \ \text { Somewhat irrelevant } & \text { \_\_\_\_(3) } \ \text { Extremely irrelevant } & \text { \_\_\_\_(4) } \end{array}$
One hundred people answer the question after seeing Commercial A and a different 100 people answer this question after seeing Commercial B.The mean response on this measure for both commercials is 2.3.The standard deviation for Commercial A is 1.1 and the standard deviation for Commercial B is 1.9.
This means that dispersal of scores for Commercial B is larger than the dispersal of scores for Commercial A.
