Flashcards in Psychology Final (Test 4) Deck (20):

1

## Factorial ANOVA

### - at least two independent variables/predictors/factors

2

## Main-Effects

###
- looking if there is a difference between the levels of the ONE variable

- "is there a difference with the orientation of psychology used in therapy?"

3

## Interactions

###
- looking to see how the variables interact/depend on each other

- "does life satisfaction DEPEND on how many clubs you belong to"

- "does attention DEPEND on the relationship and emotion"

4

## Interpretation

###
- estimated by looking at the means

- dependent variable on the Y-axis

5

## Terminology

###
- number of variables > at least two [orientation, time practiced]

- levels for each > orientation for psychology has 3 LEVELS [cognitive, psychodynamic, gestalt]

6

## Correlation

### - relationship between two continuous variables

7

## scatterplot

### - displays scores of individuals simultaneously

8

## positive relationship

###
- direct

- line points to top right

9

## negative relationship

###
- non-direct

- line points to the bottom right

10

## non-realtionship

###
- no relationship

- no directionality

11

## strength

###
- range rom 1 to -1

- the closer to 1/-1, the stronger the relationship

- coefficient = r

- sign = positive/negative

- value = strength of relationship

12

## effect size

###
large = .50

medium = .30

small = .10

13

## correlation formula

### r = ∑(X - Mx)(Y - My)/√(SSx)(SSy)

14

## correlation df

### df = N - 2

15

## Chi-Square

###
- examine multiple categorical/nominal variables

- no means

16

## goodness of fit

###
- does the data fit expectations

- null = test equality OR test pattern

17

## Independence

###
- are the variables independent of each other > two variables

- look at relation > chi-sq

18

## chi-square formula [both]

### ∑(O-E)²) / E

19

## contingency table

### - displays the frequency for each level of one nominal/categorical variable crossed with each level of the other nominal/categorical variable
