WebSep 7, 2024 · IQR = Q3 – Q1 IQR = 287 – 110 = 177 The interquartile range of your data is 177 minutes. Just like the range, the interquartile range uses only 2 values in its calculation. But the IQR is less affected by outliers: the 2 values come from the middle half of the data set, so they are unlikely to be extreme scores. 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.

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. WebThe interquartile range, or IQR, can be calculated by subtracting the first quartile value ( Q1) from the third quartile value ( Q3 ): Hence, 1.5 IQR above the third quartile is: 1.5 IQR below the first quartile is: The upper whisker boundary of the box-plot is the largest data value that is within 1.5 IQR above the third quartile.
