Find the mean, median and mode of these numbers: 9, 10, 9, 9, 11, 9, 10, 9, 9, 10 2. Find the mean, median and mode of these numbers: 5, 4, 2, 1, 6, 5, 3, 2, 4, 2, 5, 5, 2 5. In a study, college students and older adults were presented with this statement: "Social security payments are important as a means of income for the elderly." After reading this statement, participants identified the extent to which they agreed or disagreed with the statement using a Likert Scale, which is a common measurement of attitudes. Participants had five response options, ranging from "strongly agree" (1) to "strongly disagree" (5). The two frequency distributions that follow show the responses of college students and older adults to the statement above. Treat these data as population data. For each distribution, find the mean, median and mode. College Students' Level of Agreement Older Adults' Level of Agreement X X 5 5 4 4 4 3 2 3 2 1 2 1 2 st 1 6
