Question

The ordered data are below

658 789 1,306 1,900 1,922 2,077
2,409 2,768 3,603 4,291 5,744 6,502
7,528 8,355 8,358 10,463 11,463 14,163
The middle value for 21 observations is observation ___ , so the median of the data is _____ million dollars.

Answer 1

There are 21 observations in the data set, which is an odd number. Therefore, the middle value will be the (n+1)/2th observation, where n is the total number of observations.

The middle value = (21+1)/2 = 11th observation

The 11th observation is 4,291, so the median of the data is $4.291 million dollars.
