| 10551075571 | double-blind procedure | an experimental procedure in which both the research participants and the research staff are ignorant (blind) about whether the research participants have received the treatment or a placebo. Commonly used in drug-evaluation studies. | 4 | |
| 10551077508 | Placebo | a fake drug used in the testing of medication | 5 | |
| 10551081616 | correlation | A measure of the relationship between two variables | 6 | |

| 10551101808 | standard deviation | a computed measure of how much scores vary around the mean score | 10 | |
| 10551106298 | normal curve | the bell-shaped curve that describes the distribution of many physical and psychological attributes. Most scores fall near the average, and fewer and fewer scores lie near the extremes | 11 | |
| 10551108083 | Causation | A cause and effect relationship in which one variable controls the changes in another variable. | 12 | |

| 10551260665 | Hypothesis | A testable prediction, often implied by a theory | 16 | |
