Describe whether a Type I error and whether a Type II error are possible in this study.
Read the following research report and answer the question that follow.
A researcher compares men's and women's attitudes toward dating their best friend's former girl/boy friend. Specifically, college students are asked to read a story describing a situation in which their best friend breaks up with a partner and they later have an opportunity to date their best friend's former partner. Men and women rate the likelihood they would choose to date their best friend's former partner using a 10-point scale (0 = not at all likely and 9 = completely likely). In addition, participants rate the extent to which a similar situation has occurred to them using a 10-point scale (0 = not at all and 9 = completely). The mean ratings for each question for the two groups, men and women, are presented below:
A Type I error is possible if, in fact, the null hypothesis of no difference between men and women for the likelihood of dating question is true (in the population of men and women), and therefore, should not have been rejected. The probability of this Type I error is the level of significance, or alpha (p = .05). A Type II error occurs when a false null hypothesis is not rejected. This is possible if there truly is a difference for men's and women's experience of a similar situation (in the population), but the results for this sample did not indicate this difference. The experiment or statistical test may not have been sensitive or powerful enough to detect this difference.
