Study Notes
Measures of Variability
- The spread of values on either side of the center of a distribution is referred to as variability.
- Variability is a measure that indicates how widely individuals in a group vary, and it is represented by a numerical value.
- Variance is a measure of variability that indicates the spread of values in a distribution.
- A large variance indicates that the data points are widely spread out, while a small variance indicates that the data points are closer to the mean.
- Standard deviation is another measure of variability that provides a measure of the degree to which scores in a distribution vary.
- A small standard deviation indicates that the data points are closer to the mean, while a large standard deviation indicates that the data points are more dispersed.
- In general, measures of variability help to understand the spread of data and give insights into how individual data points differ from the average value.
