27
Q

Researchers attempt to categorize the subjects and ensure that the control group has members similar to those in the experimental group

A

Group-matching

28
Q

Occurs when a researcher unconsciously affects results, data, or a participant in an experiment due to subjective influence

A

Experimenter bias

29
Q

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

A

Double-blind procedure

30
Q

An experimental procedure in which the experimenters but not the subjects know the makeup of the test and control groups during the actual course of the experiments

A

Single-blind procedure

31
Q

Phenomenon in which the results of elections, studies, polls, etc. become non-representative because the participants disproportionately possess certain traits which affect the outcome

A

Participant bias

32
Q

Describes the tendency of survey respondents to answer questions in a manner that will be viewed favorably by others. It can take the form of over-reporting “good behavior” or under-reporting “bad”, or undesirable behavior

A

Social desirability

33
Q

The alteration of behavior by the subjects of a study due to their awareness of being observed

A

Hawthorne effect

34
Q

Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition, which the recipient assumes is an active agent

A

Placebo effect

35
Q

Exists when one variable decreases as the other variable decreases, or one variable increases while the other increases

A

Positive correlation

36
Q

When two variables have an inverse relationship. This means that as one variable increases, the other decreases, and vice versa

A

Negative correlation

37
Q

A technique for ascertaining the self-reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group

A

Survey

38
Q

Refers to the number of people who answered the survey divided by the number of people in the sample. It is usually expressed in the form of a percentage.

A

Response rate

39
Q

Observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation

A

Naturalistic observation

40
Q

A descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles

A

Case study

41
Q

Numerical data used to measure and describe characteristics of groups. Includes measures of central tendency and measures of variation

Q

A summary of how often different scores occur within a sample of scores

A

43
Q

The arithmetic average of a distribution, obtained by adding the scores and then dividing by the number of scores

Q

The fact or quality of being different, divergent, or inconsistent

A

Variance

51
Q

Indicates how many standard deviations an element is from the mean

A symmetrical, bell-shaped curve that describes the distribution of many types of data; most scores fall near the mean (about 68% fall within one standard deviation of it) and fewer and fewer near the extremes

A

Normal curve

53
Q

A measure of the extent to which two variables change together, and thus of how well either variable predicts the other

Correlation

54
Q

A statistical index of the relationship between two variables (from -1 to 1)

A

Correlation coefficient

55
Q

A graphed cluster of dots, each of which represents the values of two variables. The slope of the points suggest the relationship between the two variables. The amount of scatter suggests the strength of the correlation (little scatter indicates high correlation)

A

Line of best fit

57
Q

A

Inferential statistics

59
Q

Error in a statistical analysis arising from the unrepresentativeness of the sample taken

A

Sampling error

60

P value

61
Q
