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.
Count characters, words, spaces, tabs and line breaks in a sample of text. Count unique characters to calculate character frequency.
Count words, characters, and whitespace in a sample of text. Count unique words to calculate word density.
Coin Flipper simulates a coin toss for heads or tails. Flip a coin to get a random heads or tails result and tally percentage outcomes up to 100,000 flips.
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.
Create PIN numbers of 1 to 100 digits long with or without repeats.
Calculate the percent error of the Experimental (measured) value to the Theoretical (actual) value, or
\[ \text{Percent Error} = \dfrac{| E-T |}{| T |}\times100 \]Draw 1 to 52 cards randomly from a shuffled deck of playing cards.
Randomly pick a name or multiple names from a list. Sort a list of names or generate multiple picks with repeats.
Generate one or more random numbers from a custom range of numbers you select with or without repeats and sorting.
Pick a randomly generated number between 1 and 10.
Pick a randomly generated number between 1 and 100.
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 the sum of a set of numbers. Calculator performs addition or summation to compute the total amount of entered data set.
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.
