COURSE

Statistics Intermediate: Averages and Variability

Learn how to summarize distributions using the mean, the median, and the mode.

This course will teach you how to measure variability using variance or standard deviation, and how to locate and compare values using z-scores.

By the end of this course, you'll be able to:

  • Summarize a distribution using the mean, the weighted mean, the median, and the mode.
  • Measure the variability of a distribution using the variance and the standard deviation.
  • Locate and compare values using z-scores.
