The interquartile range, often abbreviated IQR, is the difference between the third quartile and the first quartile. IQR = Q3 – Q1. This tells us how spread out the middle 50% of values are in a given dataset. The following examples show how to find the interquartile range (IQR) of a box plot in practice.

WebJan 22, 2024 · The area inside the box (50% of the data) is known as the Inter Quartile Range. The IQR is calculated as – IQR = Q3-Q1 Outliers are the data points below and above the lower and upper limit. The lower and upper limit is calculated as – Lower Limit = Q1 - 1.5*IQR Upper Limit = Q3 + 1.5*IQR WebIn descriptive statistics, the interquartile range (IQR) is a measure of statistical dispersion, which is the spread of the data. The IQR may also be called the midspread, middle 50%, fourth spread, or H‑spread. It is defined as the difference between the 75th and 25th percentiles of the data. dickerson auction

WebIQR = Q3 – Q1 Equivalently, the interquartile range is the region between the 75th and 25th percentile (75 – 25 = 50% of the data). Using the IQR formula, we need to find the values for Q3 and Q1. To do that, simply order your data from low to high and split the value into four equal portions. I’ve divided the dataset below into quartiles. WebIn a box and whiskers plot, the ends of the box and its center line mark the locations of these three quartiles. The distance between Q3 and Q1 is known as the interquartile range (IQR) and plays a major part in how long the whiskers extending from the box are.
