Question

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

Answer 1

Mode: 1

Mean: 1.9

Range: 2

Explanation:

Mode: the number that occurs more often

Mean: To find the mean, add all the numbers together then divide by the number of numbers.

Range: is the difference between the largest and the smallest value.

--------------------------------------------------------------------------------------------------------------

Mode: 1,1,1,1,2,2,2,3,3,3. 1 is mostly being occurred so 1 is the mode.

Mean: 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 = 19 divided by 10 equals 1.9.

Range: the largest number is 3. The smallest number is 1. 3 - 1 = 2

Answer 2

The median, mean, and mode of the data set are 2, 1.9, and 1.

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, 3, 2 would be the median. In this case, the order would be 1, 1, 1, 1, 2, 2, 2, 3, 3, 3. The two numbers in the middle are 2 and 2, their average is 2, 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 19, so the mean of this data set is 1.9. The mode of a data set is the value that occurs the most in a set. In this case, 1 occurs four times, 2 occurs three times, and 3 occurs three times, so the mode of this data set is 1.
