Study Notes
Standard Error of a Statistic
- Standard error quantifies the variability of a statistic from different samples.
- It reflects the precision of the sample mean as an estimate of the population mean.
Influences on Standard Error
- Measurement error: Refers to errors that occur in collecting or recording data, impacting overall accuracy.
- Sampling error: Arises when a sample does not perfectly represent the population, leading to discrepancies in statistics.
- Fluctuations from sample: Variations that occur due to different samples drawn from the same population, affecting the reliability of estimates.
- Fluctuations in administration: Changes or errors in how data is administered can also contribute to variability in results.
