1

belief bias

we are more likely to believe an argument with incorrect reasoning it has a logical claim

New cards
2

Simpson’s Paradox

the results of 1 trial may be different than the overall data

New cards
3

base rate fallacy

you have to take the number of people in each category within the entire population into account

New cards
4

construct

concept that cannot be directly observed

New cards
5

measure

method used to gather data

New cards
6

variable

results

New cards
7

operalization

turning a construct into a measurement

New cards
8

steps to operalization

being precise about what you are measuring, choose an appropriate method, define variables

New cards
9

nominal

discrete categories

New cards
10

ordinal

ranked categories

New cards
11

interval

ranking with known intervals

New cards
12

ratio

ranking with known intervals and a meaningful 0

New cards
13

continuous

for any data point there can be an intermediate value

New cards
14

continuous measurements are

interval and ratio

New cards
15

discrete

there are 2 data points without an intermediate value in between them

New cards
16

discrete measurements are

nominal, ordinal, interval, ratio

New cards
17

Likert scale

measuring preferences on a scale

New cards
18

test-retest reliability

getting similar results across multiple repeats of an experiment

New cards
19

interrater reliability

2 different people get consistent measurements

New cards
20

internal consistency

do different parts of the measurement that perform the same function give similar answers

New cards
21

predictor variable

doing the explaining

New cards
22

outcome variable

being explained

New cards
23

internal validity

extent to which you can draw causal relationships between variables

New cards
24

external validity

extent to which you would see the same results in the general population

New cards
25

construct validity

are you measuring what you think you’re measuring

New cards
26

face validity

do the questions appear to be measuring that they are intended for

New cards
27

reliability

how consistent scores are

New cards
28

validity

how accurate the data are

New cards
29

mean

average

New cards
30

median

middle value

New cards
31

mode

number that occurs most often

New cards
32

positive skew

fewer values at high numbers, median closer to 25th percentile, mean is less than median

New cards
33

negative skew

more values at high numbers, median closer to 75th percentile, mean is greater than median

New cards
34

kurtosis

how pointy a graph is

New cards
35

range

greatest value-smallest value

New cards
36

IQR

75th percentile-25th percentile

New cards
37

mean standard deviation

degrees away from the mean

New cards
38

variance

measure that takes outliers into account and magnifies them

New cards
39

z-score

standardizing data to compare two unrelated constructs and interpret results in terms of standard deviation
