Researcher Teresa Amabile recruited 47 experienced creative writers who were college students and divided them at random into two groups. The students in one group were given a list of statements about external reasons (E) for writing, such as public recognition, making money, or pleasing their parents. Students in the other group were given a list of statements about internal reasons (I) for writing, such as expressing yourself and enjoying wordplay. Both groups were then instructed to write a poem about laughter. Each student's poem was rated separately by 12 different poets using a creativity scale. These ratings were averaged to obtain an overall creativity score for each poem. Parallel dotplots of the two groups' creativity scores are shownhere.

Reward lntemal (1) External (E) . O 0.. O O. O 00...... 0 Is the variability in creativity scores similar or different for the two groups? C) The variability in creativity scores is different for the two groups because the minimum for the \"external rewar \" distribution is much lower than the minimum for the \"internal reward\" distribution. O The variability in creativity scores is similar for the two groups because their shapes are similar. 0 The variability in creativity scores is diiferent for the two groups because the maximum for the \"internal rewar \" distribution is much higher than the maximum for the \"external rewar \" distribution. 0 The variability in creativity scores is similar for the two groups because the \"external reward\" distribution varies from 5 to about 24 and the \"internal reward\" distribution varies from about 12 to 30. O The variability in creativity scores is different for the two groups because their medians are different
