Outlier Calculator. Enter numbers separated by comma [example1], space [example2] or line break [example3]: If your text has non-numeric content, use our Number Extractor for cleaner calculations. Embed Outlier Calculator Widget. The Outlier Calculator is used to calculate the outliers of a set of numbers (Step by Step).
- An outlier in a distribution is a number that is more than 1.5 times the length of the box away from either the lower or upper quartiles. Specifical...
- In descriptive statistics, the interquartile range (IQR) is a measure of statistical dispersion, being equal to the difference between the third qu...
- The first quartile, also called the lower quartile, is equal to the data at the 25th percentile of the data. The third quartile, also called the up...
- There are several different methods for calculating quartiles. This calculator uses a method described by Moore and McCabe to find quartile values....
Apr 27, 2024 · However, to calculate the quartiles, we need to know the minimum, maximum, and median, so in fact, we need all of them. With that taken care of, we're finally ready to define outliers formally. 💡 An outlier is an entry x which satisfies one of the below inequalities: x < Q1 − 1.5 × IQR or x > Q3 + 1.5 × IQR.
The conclusion in this case since all the outcomes \ (X\) are within the values of \ (Lower = -20.5\) and \ (Upper = 47.5\), then there are no outliers. Use this Outlier Calculator by entering your sample data. This calculator will show you all the steps to apply the "1.5 x IQR" rule to detect the outliers.

What is standard deviation?
The statistical analysis that measures dispersion of a data set from the mean position is called standard deviation.
What is regression analysis?
The statistical process that describes relationship among dependent variable and one or more independent variables is called regression analysis.
There is a broad use of outlier detection in the field of cybersecurity, military surveillance for the sake of preventing attacks, detection of any mishap with credit cards and many more. This is why the use of free online outlier calculator is preferred around the globe to depict any fault in the systems so that any challenging situation could be ...

Nov 30, 2021 · Sort your data from low to high. Identify the first quartile (Q1), the median, and the third quartile (Q3). Calculate your IQR = Q3 – Q1. Calculate your upper fence = Q3 + (1.5 * IQR) Calculate your lower fence = Q1 – (1.5 * IQR) Use your fences to highlight any outliers, all values that fall outside your fences.
- Outliers are extreme values that differ from most values in the dataset. You find outliers at the extreme ends of your dataset.

So it seems that outliers have the biggest effect on the mean, and not so much on the median or mode. Hint: calculate the median and mode when you have outliers. You can also try the Geometric Mean and Harmonic Mean, they may work better. Mathopolis: Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 Q9 Q10.

Outliers are calculated in the following manner. First the median and quartile values are calculated. The IQR (interquartile range) is then calculated as the difference between the first and third quartile values. The IQR is multiplied by 1.5, and any point which is less than the first quartile, or greater than the third quartile by more than ...
