Suppose a researcher wanted to conduct a study to determine if there was a statistically significant difference between men and women on their mean score on a happiness scale. The researcher hypothesized that the results would show that the women were significantly happier than were the men. What kind of hypothesis did the researcher make?
Answer (1)
In this scenario, the researcher has made a directional hypothesis , also known as a one-tailed hypothesis.
This type of hypothesis predicts not only that there will be a difference between the groups being studied (men and women in this case), but also specifies the direction of the difference. Here, the researcher is specifically hypothesizing that women will score higher on the happiness scale than men, indicating that women are significantly happier. ;
