Guided Notes
3 key concepts
- 1
Standard error is a statistic that indicates the precision of your data.
- 2
Standard error is calculated by dividing the standard deviation by the square root of the sample size.
- 3
A smaller standard error indicates more precise data, while a larger standard error suggests less precise data.
