When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
The data {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7} has: Median: Thee are 16 data items, so the median is the mean average of the middle two, ie the 8th and 9th numbers: median is (3 + 3) / 2 = 3 Mean: (1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 5 + 5 + 6 + 7) ÷ 16 = 55 ÷ 16 = 37/16 = 3.4375
1, 2, 2, 3, 4, 4, 5, 7, 8 Mean: 4 Median: 4 Mode: 2 and 4
The median of the numbers 2 3 4 5 6 7 8 8 is 5.5.
To find six numbers with a range of 2 and a median of 4, we can start by placing the median 4 in the middle. Since the range is 2, the numbers on either side of the median will be 2 and 6. This leaves us with the numbers 2, 4, 4, 4, 6, and 6. These six numbers have a range of 2 and a median of 4.
The median is the middle value. 2 , 2 , 3 , 4 , 5 Median = 3
The median is 4.
4
The median is 4.5
When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
(2 + 2 + 3 + 5) / 4 = 12 / 4 = 3

2.5 is the median
