LOWER EXTREME FORMULA HOW TO

The above steps would sort the call duration column with the highest values at the top. In the Sort dialog box, select ‘Duration’ in the Sort by drop-down and ‘Largest to Smallest’ in the Order drop-down.In the Editing group, click on the Sort & Filter icon.Select the Column Header of the column you want to sort (cell B1 in this example).With small datasets, a quick way to identify outliers is to simply sort the data and manually go through some of the values at the top of this sorted data.Īnd since there could be outliers in both directions, make sure you first sort the data in ascending order and then in descending order and then go through the top values.īelow I have a dataset where I have call durations (in seconds) for 15 customer service calls.īelow are the steps to sort this data so that we can identify the outliers in the dataset: Now let’s see a couple of ways to find outliers in Excel.

LOWER EXTREME FORMULA HOW TO

When working with actual datasets in Excel, you can have outliers in any direction (i.e., a positive outlier or a negative outlier).Īnd to make sure that your analysis is correct, you somehow need to identify these outliers and then decide how to best treat them. The average income for each person on the bus would be a few billion dollars, which is way beyond the actual value. That’s because Bill Gates’s income is an outlier in our group, and that gives us a wrong interpretation of the data. While the average weight is not likely to change much, the average income of the people on the bus is going to skyrocket heavily. Now, what do you think this would do to the average weight and the average income of the people on the bus. Now somewhere in the middle of our route, the bus stops, and Bill Gates hops in. For the purpose of this tutorial, let’s consider the average weight to be 220 pounds and the average yearly income to be $70,000. All the people are in a similar weight group and income group. Let’s say 30 people are traveling in a bus from destination A to destination B. When you have an outlier in the data, it can skew your data which can lead to incorrect inferences. What are Outliers and Why is it Important to Find these?Īn outlier is a data point that is way beyond the other data points in the data set.
