Generate an online stem and leaf plot, or stemplot, and calculate basic descriptive statistics for a sample data set with 4 or more values and up to 2500 values, all non-negative. Enter values separated by commas such as 1, 2, 4, 7, 7, 10, 2, 4, 5.

You can also copy and paste lines of data points from documents such as Excel spreadsheets or text documents in the following formats with or without commas:

Notes:

  • Does not currently handle values less than 0.
  • Does not handle decimals and they will be truncated. If you need to work with decimals you can multiply all of your values by a factor of 10 and calculate based on those.  You will just need to interpret the results appropriately.
  • If you really need to work with negative values please send me a calculation request.

For additional descriptive statistical values see Descriptive Statistics Calculator.

Basic Statistics Formulas and Calculations

Minimum
The smallest value in a sample data set.
Maximum
The largest value in a sample data set.
Sum
The total of all data values.
(x1 + x2 + x3 + ... + xn)
Count (n)
The total number of data values in a data set.
Mean
The sum of all of the data divided by the count;
mean = sum / n.
Median
The numeric value separating the higher half of the sample data from the lower half.
Mode
The value or values that occur most frequently in the data set.
Standard Deviation (s)
The square root of the variance;
2√variance or variance = s2
Variance
The sum of the squared differences between data values and the mean, divided by the count - 1;
[ (x1 - mean)2 + (x2 - mean)2 + (x3 - mean)2 + ... + (xn - mean)2 ] / [n - 1]
