| probability of each value of a random variable | |
| qualitative variables; take on names that are names or labels | |
| study that obtains data from every member of a population | |
| sampling distribution of any statistic will be normal or close to normal, if the sample size is large enough | |
| r^2; proportion of the variance inthe dependent variable that is predictable from the independent variable | |
| Q3-Q1; measure of variability | |
| used to express degree of encertainty associated with a sample statistic; interval estimate combined with a probability statement | |
| occurs when experimental controls do not allow the experimenter to reasonably eliminate plausible alternative explainations for an observed relationship between independent and dep | |
| variable that can take on any value between two specified values; opposite of discrete | |
| group that receives no treatment or a neutral treatment | |
