What are the 4 descriptive statistics?
Descriptive statistics are broken down into measures of central tendency and measures of variability (spread). Measures of central tendency include the mean, median, and mode, while measures of variability include standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.
What is an example of descriptive statistics?
Descriptive statistics are used to describe or summarize data in ways that are meaningful and useful. For example, it would not be useful to know that all of the participants in our example wore blue shoes. However, it would be useful to know how spread out their anxiety ratings were.

- Measures of Central Tendency (Mean, Median, and Mode).
- Measures of Dispersion or Variation (Variance, Standard Deviation, Range).
Is chi-square and ANOVA?
