# How do you calculate q1 and q3?

Steps:
1. Step 1: Put the numbers in order.
2. Step 2: Find the median.
3. Step 3: Place parentheses around the numbers above and below the median. Not necessary statistically, but it makes Q1 and Q3 easier to spot.
4. Step 4: Find Q1 and Q3.
5. Step 5: Subtract Q1 from Q3 to find the interquartile range.

Correspondingly, how do you find the first and third quartile?

To find the quartiles of this data set, use the following steps:
1. Order the data from least to greatest.
2. Find the median of the data set and divide the data set into two halves.
3. Find the median of the two halves.

What does the third quartile tell you?

Mathwords: Third Quartile. For a set of data, a number for which 75% of the data is less than that number. The third quartile is the same as the median of the part of the data which is greater than the median. Same as 75th percentile.
