Standard error
Middle bar always population mean
SE = Does samples vary from population mean
2 samples from population may have differing SE
Sampling error
- variation from population
Is difference due to sample variation or manipulation
For each sample there is a mean (circle in the middle) and an upper and lower interval (adjoining lines) which show how scores difference from population mean
- Samples whose upper interval and lower interval do not at all fall on population mean don't contain 'true value'
