- 1What is a confidence interval?The estimate of where the population mean lies
- 2What is Power?The ability of a test to detect if it actually exists, the probability of not making a type II error, can determine how big a sample is required to detect an effect of a certain size
- 3What is an alpha level?The probability of falsely rejecting the null hypothesis (Type II error)
- 4What is a beta level?The probability of falsely failing to reject the null hypothesis (Type II error)
- 5How do you work out the effect size of a study?Cohen's d (and others)
- 6What is a priori?Using power and effect size to work out the necessary sample to detect an effect
- 7What does a 'spurious' relationship mean?A relationship that appears to be true because each variable is related to a third one
- 8What is family-wise error rates?The probability of making one of more false discoveries/ type I errors when performing multiple hypothesis tests
