Excel can help you make all sorts of calculations. Here's a selection of Excel's statistical worksheet functions. Each one returns a value into a selected cell.Check out these functions for central tendency and variability.
| Function |
What it calculates |
| AVERAGE |
Mean of a set of numbers |
| AVERAGEIF |
Mean of a set of numbers that meet a condition |
| AVERAGEIFS |
Mean of a set of numbers that meet one or more conditions |
| HARMEAN |
Harmonic mean of a set of positive numbers |
| GEOMEAN |
Geometric mean of a set of positive numbers |
| MODE.SNGL |
Mode of a set of numbers |
| MEDIAN |
Median of a set of numbers |
| VAR.P |
Variance of a set of numbers considered to be a population |
| VAR.S |
Variance of a set of numbers considered to be a sample |
| STDEV.P |
Standard deviation of a set of numbers considered to be a population |
| STDEV.S |
Standard deviation of a set of numbers considered to be a sample |
| STANDARDIZE |
A standard score based on a given mean and standard deviation |
These handy functions for relative standing can also be very useful.
| Function |
What it calculates |
| RANK.EQ |
Rank of a number in a set of numbers. If more than one number has the same rank, it returns the top rank of those numbers. |
| RANK.AVG |
Rank of a number in a set of numbers. If more than one number has the same rank, it returns their average. |
| PERCENTRANK.INC |
Rank of a number in a set of numbers, expressed as a percent of the numbers it's greater than or equal to. |
| PERCENTRANT.EXC |
Rank of a number in a set of numbers, expressed as a percent of the numbers it's greater than. |
| PERCENTILE.INC |
The indicated percentile in a set of numbers, in terms of "greater than or equal to." |
| PERCENTILE.EXC |
The indicated percentile in a set of numbers, in terms of "greater than." |
| QUARTILE.INC |
The 1st, 2nd, 3rd, or 4th quartile of a set of numbers, in terms of "greater than or equal to." |
| QUARTILE.EXC |
The 1st, 2nd, 3rd, or 4th quartile of a set of numbers, in terms of "greater than." |
These functions for correlation and regression are also good ones to know.
| Function |
What it Calculates |
| CORREL |
Correlation coefficient between two sets of numbers |
| PEARSON |
Same as CORREL. (Go figure!) |
| RSQ |
Coefficient of determination between two sets of numbers (square of the correlation coefficient) |
| SLOPE |
Slope of a regression line through two sets of numbers |
| INTERCEPT |
Intercept of a regression line through two sets of numbers |
| STEYX |
Standard error of estimate for a regression line through two sets of numbers |
