Question

Find the mode, median, mean, and range for each data set. Round the mean to two decimals places, where necessary.

Answer 1

Answer:

The median, mean, and mode of the data set are 5, 4.8, and both 4 and 5 respectively.

Step-by-step explanation:

To find the median of a data set, line up all values from greatest to least and find the number in the center. For example, in the set 1; 2; and 3, 2 would be the median. In this case, the order would be 2, 4, 4, 4, 5, 5, 5, 6, 6, 7. The two numbers in the middle are 5 and 5, their average is 5, so that would be the median. The mean of a data set is the average of all data values in a set. In this case, there are 10 data values, and their total sum is 48, so the mean of this data set is 4.8. The mode of a data set is the value that occurs the most in a set. In this case, 2 occurs once, 4 occurs three times, 5 occurs three times, 6 occurs twice, and 7 occurs once, so the mode of this data set is both 4 and 5.
