Question

8. The researchers from Question 7 record how long the participants who decided to hold an animal spent doing so (time measured in seconds). Below is their data:

140                  179                  151                  200                  182                  135                  300

152                  178                  199                  247                  142                  163                  184

297                  213                  351                  159                  280

A.Create a grouped frequency distribution for their data. (1.5 points)

B. Using the grouped frequency distribution from Question 8, you should create a histogram to display the class intervals. Remember to clearly label your axes for the histogram. (1.5 points)

C. Explain why a histogram was the appropriate type of graph to use to display the data in Question 9. (1 point)

D. How would you describe the shape of the histogram you created in Question 9? (1 point)

E. Which measure of central tendency would be most appropriate to use to identify the “typical” score, and why? (1.5 points)
