| Situation in which researcher’s expectations influence an experiment | Self-fullfilling prophecy |
| Change in a participant’s behaviour from the belief that treatment will have an effect rather than from actual treatment | Placebo effect |
| Measure of variability, the average distance of every score from the mean | Standard deviation |
| Situation in which experimenter and participants are unaware of who received treatment. | Double-blind experiment |
| Numerical methods used to determine if data supports a hypothesis | Inferential statistics |
| Situation in which participants are unaware of who received treatment | Single-blind experiment |
| Listing and summarizing data in a practical and efficient way | Descriptive statistics |
| Measure of variability, the mean of the squares of the deviations from the mean of the set of data | Variance |
| Describe two methods a researcher could use to avoid obtaining a non-representative sample. | Random sampling, every member has an equal chance of selection, or stratified sampling, which divides the population into subgroups and randomly samples to ensure all groups are represented. |
| What is a correlation and what kind of a correlation would you expect from a sample of a student's grades and their classroom attendance? | Statistical relationship between two variables, at the extent they change together. Positive correlation as attendance increases, grades increase. |

Yes, about 65% of the participants delivered high shocks despite the distress of the learner. Showing influence of authority on obedience. |
| Describe the three measures of central tendency. | Mean (average of values), median (middle when ordered), mode (most occurring value) |
| Describe the two measures of variability and what do they tell a psychologist about the results of the research | How much scores in a dataset differ from the mean, it tells how much individuals differ in their responses. How spread out data points are from the mean of a dataset, it tells how much an individual's scores typically differ from the average. |
| What information is provided by a correlation coefficient? | Correlation coefficient provides the strength and direction of a linear relationship between two variables. |
| Various statistics are used in sports, pick a sport and list 5 statistics that might be used | In basketball, five common statistics are Points per Game, Field Goal percentage, rebounds, assists, and turnovers. |
