KIN 200 Exam 2
A report includes a statement that the "average" test score of applicants to medical schools is 28.4. What is the role of the term "average" in statistics? Should another term be used in place of average?
The term "average" is not used in statistics. The term "mean" should be used for the result obtained by adding all of the data values and dividing the total by the number of data values.
In what sense are the mean, median, mode, and midrange measures of "center"?
They use different approaches for providing a value (or values) of the center or middle of the sorted list of data.
Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given question. Listed below are the jersey numbers of 11 players randomly selected from the roster of a championship sports team. What do the results tell us? 29, 2, 39, 89, 62, 86, 78, 76, 46, 88, 75 e. What do the results tell us?
a. 60.9 b. 75 c. no mode d. 45.5 e. The jersey numbers are nominal data and they do not measure or count anything, so the resulting statistics are meaningless.
