Outliers are data points that differ significantly from other observations. They can be caused by measurement errors, data entry mistakes, or simply natural variation. Identifying outliers is important because they can skew the results of statistical analyses.
There are several ways to calculate outliers in Excel. One common method is to use the Interquartile Range (IQR). The IQR is the difference between the 75th percentile and the 25th percentile. Data points that are more than 1.5 times the IQR above the 75th percentile or below the 25th percentile are considered outliers.
