Inter-Quartile Example on the Basis of the Above Definition Let's calculate the interquartile range of the below data So, there are a total of 3 quartiles The first quartile also known as the lower quartile is represented by Q 1, the second quartile is represented by Q 2, and the last third quartile also known as the upper quartile is represented by Q 3. As we know quartiles are the divided values that divide the complete series into four equal parts. The interquartile definition states that the interquartile range is the difference between the third and the first quartiles. Interquartile range Definition and Example And all the points that fall beyond the outer fences are known as extreme outliers. Q 3 is the middle value in the second half.Īny data point that is going to fall between the inner and outer fences is said to be the mid-outliners. Q 1 here is the middle value in the first half If we talk about fences then there are four relevant fences. From the data or on a box plot a fence is used to identify and categorize the type of outliers. The interquartile range is often used to measure or find the outliers in the data. The interquartile range is equal to quartile 3 minus quartile 1. Q 3 - It is the middle value in the second half of the rank-ordered data set. Q 1 - It is the middle value in the first half of the rank-order data And they are represented by Q 1, Q 2, and Q 3. The values that split each part are known as the first, second, and third quartile. Quartile divides the range of data into four equal parts. The interquartile range is a measure of variability based on splitting data into quartiles. The interquartile range can be used to denote or indicate the variability of the set provided to you. The interquartile range is used to explain the difference between the upper and lower quartiles in the set of data. Instead of data, there are two quartiles, namely the upper quartile and the lower quartile. The interquartile range is actually the measure of static depression and the spread of the data.
