Descriptive Statistics

Summarize your data by finding the mean, median, standard deviation, and other descriptive statistics.

Min and Max
I demonstrate how to use =min() and =max() to calculate the minimum and maximum scores in a dataset.

Mean, Median, and Standard Deviation
Learn how to use the =average(), =median(), and =stdev() functions to calculate the mean, median, and standard deviation.

Descriptive statistics for nominal or ordinal data: Frequencies using =countif
The =countif() function calculates frequencies in Excel. You’ll learn how to use =countif() to tally how many people selected strongly agree, agree, disagree, and strongly disagree options in a satisfaction survey.

Descriptive statistics for nominal or ordinal data: Countif with $
Next, use $ symbols within your =countif function to save even more time as you tally responses on a satisfaction survey.

Descriptive statistics for interval or ratio data

I show you how to calculate a variety of descriptive statistics for interval or ratio data, including:

  • Basic data cleaning: =count, =countblank
  • Measures of central tendency: =average, =median, =mode
  • Measures of dispersion: =var, =stdev, =min, =max, =quartile, ranges

This tutorial is designed for people with a basic statistics or social science background. That is, I explain how to translate your preexisting knowledge about descriptive statistics into simple Excel formulas rather than explaining why these metrics are useful.

Filtering a list to find unique entries

How many different categories (like states) are represented in your dataset? In this video, I teach you three strategies for determining how many unique entries are represented:

  • Filters
  • Pivot table tallies
  • Advanced filters
