- 3Critical valueA value from a table for the appropriate statistical test to which an observed value is compared.Indicates if pattern is significant
- 4Observed valueThe single number calculated by a statistical test from the scores observed in the study.Compared to critical value
- 5Type 1 errorConcluded that there is a difference between variables when there isn't and accepted alternative hypothesis when it is actually due to chance
- 6Type 2 ErrorAccepting the null hypothesis when it is not due to chance and there is a correlation between variables
- 7Two- tailed alternative hypothesisThere will be a significant difference between brain volume and cleverness
