(4 + 23)/2 = 27/2 = 13.5
Then that number will be the median. For example, if your set is 4, 4, 19, 20, 23, 23, 23, 43, 62, 76 and 89, then the second 23 is the middle number, and so it is the Median.
The median is 18
The median is 19.
The median is 4
The median is 19.
Mean: 25 Median: 25 Mode: 24, 26 Range: 4
The mean and median become smaller, the mode does not change.
As 23 is a single number, its median is itself. If you meant 2 and 3, then the median is 2.5, the value halfway between them, which in this case is also the mean of the two numbers.
45
S={1,2,4,5,7}, the median is 4
The median is 4
