What is the null hypothesis?
The hypothesis that there is no effect in the population
What is a sampling error?
A sample that doesn’t represent the population
What could happen in a sampling error?
Could end up with 2 samples that actually come from different populations
Could end up with a sample from one of each population and be in danger of making a type 1 error.
What happens if the p value is > .05?
The probability is high that the null hypothesis is true
The outcome is not significant and the effect is unlikely to be found in the population so cannot be generalised.
What happens if there is a small SE?
Means the sample is close to the population and unlikely to have sampling error
