# Statistical Analysis with Excel For Dummies Cheat Sheet

Excel offers a wide range of statistical functions you can use to calculate a single value or an array of values in your Excel worksheets. The Excel Analysis Toolpak is an add-in that provides even more statistical analysis tools. Check out these handy tools to make the most of your statistical analysis.

## Some Excel Worksheet Functions for Statistical Analysis

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 |

## Excel Array Functions for Statistical Analysis

An array formula calculates a set of values rather than just one. Here are Excel’s statistical array functions. Each one returns an array of values into a selected array of cells.

Function | Calculates An Array Of … |

FREQUENCY | Frequencies of values in a set of values |

MODE.MULT | Modes of a set of numbers |

LINEST | Regression statistics based on linear regression through two or more sets of numbers |

LOGEST | Regression statistics based on curvilinear regression through two or more sets of numbers |

TREND | Numbers in a linear trend, based on known data points |

GROWTH | Numbers in a curvilinear trend, based on known data points |

## Excel Data Analysis Tools

Excel’s Analysis ToolPak is a helpful add-in that provides an extensive set of statistical analysis tools. Here are some of the tools in the ToolPak.

Tool | What it Does |

Anova: Single Factor | Analysis of variance for two or more samples |

Anova: Two Factor with Replication | Analysis of variance with two independent variables, and multiple observations in each combination of the levels of the variables. |

Anova: Two Factor without Replication | Analysis of variance with two independent variables, and one observation in each combination of the levels of the variables. You can use it for Repeated Measures ANOVA. |

Correlation | With more than two measurements on a sample of individuals, calculates a matrix of correlation coefficients for all possible pairs of the measurements |

Covariance | With more than two measurements on a sample of individuals, calculates a matrix of covariances for all possible pairs of the measurements |

Descriptive Statistics | Generates a report of central tendency, variability, and other characteristics of values in the selected range of cells |

Exponential Smoothing | In a sequence of values, calculates a prediction based on a preceding set of values, and on a prior prediction for those values |

F-Test Two Sample for Variances | Performs an F-test to compare two variances |

Histogram | Tabulates individual and cumulative frequencies for values in the selected range of cells |

Moving Average | In a sequence of values, calculates a prediction which is the average of a specified number of preceding values |

Random Number Generation | Provides a specified amount of random numbers generated from one of seven possible distributions |

Rank and Percentile | Creates a table that shows the ordinal rank and the percentage rank of each value in a set of values |

Regression | Creates a report of the regression statistics based on linear regression through a set of data containing one dependent variable and one or more independent variables |

Sampling | Creates a sample from the values in a specified range of cells |
