What is Upper or Third Quartile (Q3)?

The third quartile (Q3) also called upper quartile (QU) which is equal to the 75th percentile of the data. It splits off the lowest 75% of data from the highest 25% of the given data. Also, the third quartile value is the median of the third quartile data set or upper half of the data set.

1. Is the third quartile as same as the upper quartile?

Yes, the third quartile also called the upper quartile has 75 percent of the data below it and the top 25 percent of the data above it.


2. How do I find the upper quartile?

The upper quartile is nothing but the median of the upper half of a data set. This can be calculated by dividing the data set with the median and then dividing the upper half that lives with the median again, this median of the upper half is called upper quartile and that's the process to find the upper quartile or third quartile.


3. Why Calculate the Quartiles?

Quartiles are used to calculate the interquartile range, which is a measure of variability around the median.
