CALCULATOR USE

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
1000 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 with or without commas in the formats shown in
the table below.


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.

Below is a sample stem and leaf plot and listing of the statistical values
calculated.

BASIC STATISTICS FORMULAS AND CALCULATIONS USED IN THIS CALCULATOR


MINIMUM

Ordering a data set {x1 ≤ x2 ≤ x3 ≤ ... ≤ xn} from lowest to highest value, the
minimum is the smallest value x1.

Min=x1=min(xi)ni=1Min=x1=min(xi)i=1n


MAXIMUM

Ordering a data set {x1 ≤ x2 ≤ x3 ≤ ... ≤ xn} from lowest to highest value, the
maximum is the largest value xn.

Max=xn=max(xi)ni=1Max=xn=max(xi)i=1n


SUM

The sum is the total of all data values. {x1 + x2 + x3 + ... + xn}

Sum=∑i=1nxiSum=∑i=1nxi


SIZE

The total number of data values in a data set.

Size=n=count(xi)ni=1Size=n=count(xi)i=1n


MEAN

The sum of all of the data divided by the size. The mean is also known as the
average.

x¯¯¯=∑ni=1xinx¯=∑i=1nxin


MEDIAN

Ordering a data set {x1 ≤ x2 ≤ x3 ≤ ... ≤ xn} from lowest to highest value, the
median is the numeric value separating the upper half of the ordered sample data
from the lower half. If n is odd the median is the center value. If n is even
the median is the average of the 2 center values.

If n is odd the median is the value at position p where

p=n+12p=n+12
x˜=xpx~=xp

If n is even the median is the average of the values at positions p and p + 1
where

p=n2p=n2
x˜=xp+xp+12x~=xp+xp+12


MODE

The value or values that occur most frequently in the data set.


STANDARD DEVIATION

s=∑ni=1(xi−x¯¯¯)2n−1−−−−−−−−−−−−√s=∑i=1n(xi−x¯)2n−1


VARIANCE

s2=∑ni=1(xi−x¯¯¯)2n−1s2=∑i=1n(xi−x¯)2n−1
