Range ,[object Object],96, 94, 98, 90, 94, 85 The range for this set of data is 8 because the maximum (98) minus the minimum (90) = 8 Try One!

Find the range for the following data set: ,[object Object],16 27 10 18

Correct! ,[object Object],98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 27 because 99 (max) – 72 (min) = 27 Click here to return to the main menu!

Keep Trying! ,[object Object],98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 27 because 99 (max) – 72 (min) = 27 Click here to return to the main menu!

Median ,[object Object],The median for this set of data is 94 because it is the middle value. 85, 90, 94, 94, 96, 98 Try One! Don’t forget to put the data in order from least to greatest first!

Find the median for the following data set: ,[object Object],94 97 94.5 95

Correct! ,[object Object],98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 94.5 because it is halfway between the two middle values. (You will only do this when there is an even number of values. If the number of values is odd, the median is the number in the middle.) Reorder the values: 72, 85, 89, 92, 94, 95 , 95, 97, 98, 99 94 + 95 = 189; 189 / 2 = 94.5 Click here to return to the main menu!

Mean ,[object Object],The mean for this set of data can be found by: finding the sum of the values = 557 Dividing by the total number of values = 557 / 6 = 92.83 85, 90, 94, 94, 96, 98 Try One!

Find the mean for the following data set: ,[object Object],95 91.6 99 90

Correct! ,[object Object],98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 91.6 because when you add the values together and divide them equally (find the sum of all values and divide it by the total number of values) you get: 98 + 94 + 97 + 95 + 95 + 99 + 92 + 85 + 72 + 89 = 919 916 / 10 = 91.6 Click here to return to the main menu!
