Flashcards in Test 2 Deck (22):

1

## What letter stands fo statistical significance calculation of the probability that the association would occur randomly in the problem

### P

2

## What is a curvilinear association

###
Two variables- not a straight line

Positive (or neg) to a point then becomes opposite

3

## What is a predictor variable

### Independent variable

4

## What are Forced-choice questions

### People give their answer by picking between the best of two or more options

5

## What is multistage sampling

### One large group is randomly selected then within the group the sampling group is randomly chosen

6

## What is Cross-lag correlation

### Test to show if earlier measures of one variable are associated with later measures of another variable

7

## Observer bias is what?

### When observers see what they expected to see

8

## What is observer effects?

### Observers inadvertently change the behavior of those they are studying

9

## Cluster sampling

### One group is randomly samples and everyone in the group is used

10

## How to reduce reactivity

### Blend in, wait it out, measure behavior results rather than the behavior

11

## Outlier

12

## Parsimony

### Theory provides the simplest explanation of a phenomenon

13

###
At least two predictors

ONE criterion

14

## Mediator variable

### Additional variable that explains the WHY

15

## What is B (beta)

### Indicated the statistical test for associations between two variables controlling for ALL other identified variables

16

## Effect size

### Strength of the relationship between two or more variables

17

## Longitudinal research.

### Study conducted over multiple time points

18

## Moderator

### Explains for WHOM or WHEN two variables are strongly related

19

## Other terms for random sampling

###
