The only online outlier calculator that actually lets you upload a CSV! This calculator will help you find outliers in your numerical data. Outliers are data points that are significantly different from the rest of the data. They can be caused by errors in data collection or they can be legitimate data points that are significantly different from the rest of the data. This calculator will help you find these data points. Your data is processed in the browser and is never sent to my server.
Please remove all blank rows for accurate outlier location information. The file must be a CSV.
Upon CSV upload, the tool will search each column in your CSV for outliers in that column. For example, if you have a column named "Miles per gallon" with the values 25, 30, 32, 28, and 55, 55 will be displayed to you as an outlier because it is much further from the average of the other numbers.
This tool can only work with numbers, so any columns that contain text or other data types will not be processed.
Low sensitivity is the recommended setting. Low sensitivity will catch outliers that are far outside of the average. Higher sensitivity will return more outliers, but they will be closer to the mean than the outliers returned using low sensivity.
First row contains column headers
Outliers can be difficult to spot, especially if you have a lot of data. Outliers can be caused by errors in data collection or they can be legitimate data points that are significantly different from the rest of the data. This calculator will help you find these data points.
