A result that is significantly higher or lower than the majority of the values in your data is referred to as an outlier. Outliers can skew the results when using Excel to examine data. The mean average of a data set, for example, may accurately reflect your values.
Q1 – (1.5* IQR) is the lower range limit. This is calculated by subtracting 1.5 times the inner quartile range from your 1st quartile. Q3 + (1.5*IQR) = higher range limit This is 1.5 times quartile 3 of the IQR+. Any data that goes below or beyond these boundaries will now be classified as an anomaly.
Excel offers several underutilised functions that can significantly improve your data analysis. Its statistical capabilities are one of the best characteristics. So, using simple statistics formulas in Excel, you can simply discover outliers.
An outlier is a single observation that appears to diverge significantly from the rest of the sample. The following are some of the reasons why identifying prospective outliers is critical. An outlier could be a sign of skewed data. For instance, data could have been wrongly coded or an experiment could have been done erroneously.
