Researchers Dumas and Dunbar wanted to see whether stereotypes related to creativity can influence the creativity of a subject (2016). The 64 subjects were randomly placed into two groups of 32 each. One group was told to imagine that they were rigid librarians and another group was to imagine they were eccentric poets. As a measure of their creativity, they were then shown 10 items and asked to generate as many different uses for these items as possible. Results similar to those found by the researchers are in the file LibrarianPoet. Is there convincing evidence of a stereotype effect here? That is, is there a significant difference in average creativity (as measured by finding multiple uses for objects) between the “rigid librarians” and “eccentric poets”? Put the data in the Multiple Means applet to answer the (a)–(f). 

a. State the hypotheses to test this either in words or using appropriate symbols. 

b. Explain if the validity conditions for a theory-based test are met. 

c. What are the mean ratings for the two conditions? 

d. What are the values of the t-statistic and corresponding p-value? 

e. State your conclusion in the context of the research question. 

f. Would a statistically significant difference establish that real poets are more creative than real librarians?
