Answers:
- Min = 1
- Q1 = 2.5
- Median = 5
- Q3 = 7
- Max = 13
============================================================
How to find those answers:
The first step is to sort the data from smallest to largest.
Here is what it looks like after sorting:
1, 2, 3, 5, 5, 6, 8, 13
The middle most items are those two copies of '5'. It's a tie between them.
The midpoint is (5+5)/2 = 10/2 = 5
Therefore, the median or Q2 is 5
--------------
Next we split the data into two groups
L = {1,2,3,5} = lower set of first four items
U = {5,6,8,13} = upper set of last four items
Find the median of set L to get (2+3)/2 = 5/2 = 2.5
Then find the median of set U to get (6+8)/2 = 14/2 = 7
These medians of the subsets mentioned are the values of Q1 and Q3 respectively
Q1 = 2.5
Q3 = 7
----------------
Lastly the min and max are the smallest and largest items.
In this case 1 is the smallest and 13 is the largest
min = 1
max = 13
