2. Count how many numbers you have, add 1, then divide by 2. [(15+1)÷2=8] This gives the POSITION of the median, not the median itself.

3. Count this number of values from the front

Median =

If there is an even number of values

2. Count how many numbers you have, add 1, then divide by 2. [(16+1)÷2=8.5] This gives the POSITION of the median, not the median itself.

3. Count this number of values from the front

Median =

4+5 = 4.5
