24
Q

horns effect

A

opposite of halo effect

25
Q

correlational design

A

research design that examines the extent to which 2 variables are associated

26
Q

correlation

A

a measure of the relationship between 2 variables

27
Q

negative correlation

A

as the value of one variable changes, the other goes in the opposite direction

28
Q

positive correlation

A

as the value of one variable changes, the other goes in the same direction

29
Q

zero correlation

A

scattered

30
Q

perfect correlation

close to a linear line

31
Q

describe correlation coefficients

A

range from -1 to 1 with the absolute value indicating the strength of the relationship

32
Q

scatterplot

A

grouping of points on a 2 dimensional graph in which each do represents a single person’s data

33
Q

illusory correlation

A

the perception of a statistical association between 2 variables where none exists

34
Q

what forms the basis of many superstitions?

A

illusory correlation

35
Q

placebo effect

A

improvement resulting from the mere expectation of imporvement

36
Q

nocebo effect

A

harm resulting from the mere expectation of harm
-the expectation of pain can itself create pain

37
Q

the experimenter expectancy effect

A

researchers’ hypotheses lead them to unintentionally bias the outcome of a study

38
Q

demand characteristics

A

cues that participants pick up from a study that allow them to generate guesses regarding the researcher’s hypothesis

39
Q

informed consent

A

a procedure in which researchers must tell subjects what they’re getting into before asking them to participate

40
Q

deception

A

when researchers deliberately mislead participants about the study’s design or purpose
-participants should be informed of the deveption soon after the deception takes place

41
Q

statistics

A

application of mathematics to describing + analyzing data

42
Q

central tendency

A

-mean

Q

median

A

the middle score after ordering the scores from lowest to highest

45
Q

mode

A

most frequent score

46
Q

positive skew

A

mean > mode

range

difference between the highest/lowest scores

A

statistical method that analyzes effects across studies to determine consistent patterns of results

54
Q

2 ways statistics can be misused

the tendency to minimize the less central details of a study
