Find the lower quartile of this data set: 593, 588, 540, 434, 420, 398, 390, 375

The first quartile (or lower quartile or 25th percentile) is the median of the bottom half of the numbers. So, to find the first quartile, we need to place the numbers in value order and find the bottom half.

375   390   398   420   434   540   588   593   

So, the bottom half is

375   390   398   420   

The median of these numbers is 394.
