**First Quartile or Lower Quartile Formula**

The procedure to calculate the lower or first quartile of numbers is given here in simple steps. So, please follow the steps provided below and understand how to find out the lower quartile of numbers easily by hand.

- First, arrange the list of the data in ascending order.
- Now, the ordered data should divide into four equal quarters.
- Take the first half of the numbers to find the lower quartile.
- Now, calculate the median for the Q1 list of data.
- If the first quartile set of data is odd, then the median is the middle value.
- If the first half of the data is even, then the median is the average of mid two values.
- Finally, the median value is the Q1 value for the given set of data.
