# Statistics Calculators

Calculate the average of a set of data. Average is the same as mean.

average = sum of data / number of data values

Calculate the minimum, maximum, sum, count, mean, median, mode, standard deviation and variance for a data set.

Descriptive Statistics Calculator

Calculations include the basic descriptive statistics plus additional values. Calculate the minimum, maximum, range, sum, count, mean, median, mode, standard deviation, variance, midrange, quartiles, sum of squares, mean deviation, absolute deviation, root mean square, standard error of the mean, skewness, kurtosis, coefficient of variation and frequency for a set of data.

Calculate the grade you need on the final exam to get a desired grade for the course.

Calculate grade point average and cumulative grade point averages.

Calculate the mean of a set of data. Mean is the same as average.

mean = sum of data / number of data values

Calculate the statistical mean, median and mode for a set of data.

Convert "odds of winning" an event into a percentage chance of success.

Calculate any percentile and get a table of every 5th percentile for a given data set.

Calculate first, second and third quartiles, the interquartile range, and minimum and maximum for a data set.

Interquartile Range Calculator

Calculate first, second and third quartiles, the interquartile range, and minimum and maximum for a data set.

Generate one or more random numbers from a range of numbers.

Random Number and Letter Set Generator

Generate one or more random numbers or random letter sets from a range of numbers or letters.

Calculate the standard deviation and variance for a set of data.

Formulas include the basic descriptive statistics to calculate the minimum, maximum, range, sum, count, mean, median, mode, standard deviation, variance, midrange, percentiles, quartiles, outliers, sum of squares, mean deviation, absolute deviation, root mean square, standard error of the mean, skewness, kurtosis, kurtosis excess, and coefficient of variation.

Create stem and leaf plots, or stemplots, for sets of data values and calculate basic statistics including the minimum, maximum, sum, count, mean, median, mode, standard deviation and variance.

Calculate variance, standard deviation and variables needed to calculate variance including sample size *n*, mean and sum of squares of the sample set.

Calculate the percentage weight of two or three numbers that make up a total sum of the sample set.

Calculate the z-score using one of three methods including for a set of data.
