The interquartile range (IQR) is a statistical measure of the middle values of a sample data set that is separated into four equal parts. This middle-value grouping can provide a median range between the upper
In a boxplot graph, the box represents the data’s interquartile range (IQR), which is the 50 percent of data points above the first quartile and below the third quartile. Each whisker (line) on the side of a boxplot represents the top and bottom 25 percent of data points, where the...
Finally, the formula will return a TRUE value if the specific data is an outlier and will return a FALSE Double-click on cell E5 to use the AutoFill tool fill handle to copy the formula to the rest of the cells in column E. Thus, you can find all the remaining outliers in your da...
To find outliers, you’ll need to know your data’s IQR, Q1, and Q3 values. Take these values and input them into the equations below. Statisticians call the result for each equation an outlier gate. I’ve included these calculations in the IQR example Excel file. Q1 − 1.5 * IQR: ...
