The least to greatest calculator is here to put your numbers in ascending order, even if instead of specific values, you give it arithmetic expressions.
The mean absolute deviation calculator can calculate the mean absolute deviation around the mean, median, or any other statistically significant number.
The mean median mode calculator tells you the mean, median, mode, range, and midrange of a dataset. We also show you all the steps!
The median absolute deviation calculator can calculate the median absolute deviation of a data set of up to 50 points.
The midrange calculator will quickly calculate the midrange of a given set of data.
The minimum and maximum calculator will quickly give you the smallest and largest values in your dataset of up to fifty entries.
The MSE calculator can quickly find the mean squared error of your sample and provide you with intermediate calculations. SSE and RMSE are available as well!
The outlier calculator is here to analyze your dataset of up to thirty entries and tell you if any of them are outliers, i.e., differ a lot from the others.
Use this Pearson correlation calculator to find Pearson's r of any given dataset, as well as a general oversight on what Pearson's correlation is all about.
This percentile rank calculator finds the percentile for any data value in a dataset that contains up to 30 numbers.
Our pooled standard deviation calculator can help you measure the variability or spread of data when combining or pooling multiple datasets.
Use the population variance calculator to estimate the variance of a given population from its sample.
Our process capability index calculator helps you calculate whether the variation of your process is within specification limits and whether your process can produce the intended output.
The quartile calculator is a simple tool to help you find the quartiles of your dataset (and some additional extra information).
Try our quiz to test your understanding of Simpson’s diversity index and its real-world interpretation.
The relative standard deviation calculator presents the standard deviation as a percentage of the mean.
Our RSE calculator assists you in measuring estimate precision by calculating the ratio of the standard error to the mean.
