Quartiles are used to calculate the interquartile range, which is a measure of variability around the median. Understanding Quartiles To understand the quartile, it is important to understand themedianas ameasure of central tendency. The median in statistics is the middle value of a set of numbe...
How to Calculate Quartiles Step 1: Order the data values from smallest to largest. Step 2: Find the median {eq}Q2 {/eq} of the data set. If the size of the data set is odd, then the median is the middle data value. If the size of the data set is even, then the median is ...
2. Next, we need to calculate Q3. To calculate Q3 in Excel, simply find an empty cell and enter the formula ‘=QUARTILE(array, 3)‘. Again, replacing the ‘array‘ part with the cells that contain the data of interest. 3. Finally, to calculate the IQR, simply subtract the Q1 value...

Calculating quartiles manually can be a tedious process. Learn how to calculate quartiles in Excel using the simple quartile formula. Also, discover how learning the function can benefit you.
First, we must arrange the values in ascending or descending order to find the median. Rearranged values: 2, 4, 4, 6, 18, 26. Then, we identify the number in the middle as the median. If there are even numbers of values, we calculate the mean of the values in the middle to fin...
