| 15131568485 | survey | A study, generally in the form of an interview or questionnaire, that provides researchers with information about how people think and act. | 5 | |
| 15131568487 | random sample | A sample that fairly represents a population because each member has an equal chance of inclusion | 6 | |
| 15131568488 | sampling bias | flawed sampling process that produces an unrepresentative sample | 7 | |
| 15131568489 | naturalistic observation | Observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation | 8 | |
| 15131568490 | correlation | A measure of the relationship between two variables | 9 | |
| 15131568491 | correlation coefficient | A statistical index of the relationship between two things (from -1 to +1) | 10 | |
| 15131568493 | illusory correlation | The perception of a relationship where none exists | 11 | |
| 15131568494 | experiment | A research method in which an investigator manipulates one or more factors to observe the effect on some behavior or mental process | 12 | |
| 15131568495 | random assignment | Assigning participants to experimental and control conditions by chance, thus minimizing preexisting differences between those assigned to the different groups | 13 | |
| 15131568496 | double-blind study | An experiment in which neither the participant nor the researcher knows whether the participant has received the treatment or the placebo | 14 | |
| 15131568497 | placebo effect | Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition, which is assumed to be an active agent. | 15 | |
| 15131568498 | experimental group | A subject or group of subjects in an experiment that is exposed to the factor or condition being tested. | 16 | |
| 15131568499 | control group | In an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment. | 17 | |
| 15131568500 | independent variable | (statistics) a variable whose values are independent of changes in the values of other variables | 18 | |
| 15131568501 | confounding variable | A factor other than the independent variable that might produce an effect in an experiment. | 19 | |
| 15131568502 | dependent varibale | the outcome factor the cariable that may change in response to manipulations of the independent variables --what you are measuring (ex. obesity rates) | 20 | |
| 15131568503 | mode | Measure of central tendency that uses most frequently occurring score. | 21 | |
| 15131568504 | mean | Average | 22 | |
| 15131568505 | median | A measure of center in a set of numerical data. The median of a list of values is the value appearing at the center of a sorted version of the list - or the mean of the two central values if the list contains an even number of values. | 23 | |
| 15131568506 | range | Distance between highest and lowest scores in a set of data. | 24 | |
| 15131568507 | standard deviation | A computed measure of how much scores vary around the mean score. | 25 | |
| 15131568513 | sample | A part of the population you are studying. | 26 | |
| 15131568516 | 3 main components of scientific attitude | curiosity skepticism humility | 27 | |
| 15131568521 | positive correlation | two variable rise and fall together, such as height and weight |  | 28 |
| 15131568522 | negative correlation | variables are related inversely, one goes up and the other goes down, such as inner speech and psychological distress |  | 29 |
