Study Notes
Standard Deviation
- Standard deviation measures how dispersed the data is around the mean.
- A low standard deviation indicates that data points are closer to the mean, meaning the data is less spread out.
- A standard deviation close to zero indicates that data points are close to the mean, meaning the data is very consistent.
- A high standard deviation indicates that data points are spread out further from the mean.
