Flashcards in SPSS Deck (29):

1

## Chi-squared

### a statistical test that allows us to test a hypothesis using a sample, it provides a probability value of it occuring

2

## what does a large chi-squared mean?

### a statistically significant relationship

3

## if there is one variable which statistical tests can you do?

###
frequencies

frequencies and descriptives

4

## if there is two variables which statistical tests can you do?

### depends on the type of data

5

##
two variables

two categorical

two or more categories within variables

###
chi-squared

cross tabulation

6

##
two variables

one categorical/ one continuous

two categories within variables

non-repeated measure

### independent samples t-test

7

##
two variables

one categorical/ one continuous

two categories within variables

repeated measure

### paired samples t-test

8

##
two variables

one categorical/ one continuous

three or more categories within variables

### ANOVA

9

##
two variables

two continuous

###
correlation

simple linear regression

10

##
three variables

categorical dependent variable

### logistic regression

11

##
three variables

continuous dependent variable

### multiple linear regression

12

##
three variables

multiple dependent variables

grouping based on similarity between variables

### exporatory factor analysis

13

##
three variables

multiple dependent variables

grouping based on similarity between cases

### cluster analysis

14

## independent samples t-test

### establishes whether there is a statistically significant relationship between two variables using mean

15

## assumptions of the independent/ paired samples t-test

###
data is normally distributed (histogram)

more then 30 cases

samples have equal variance

16

## paired samples t-test

17

## ANOVA

### establishes whether there is a statistically significant relationship between three variables using variance

18

## types of variance with ANOVA

###
within group variance

between group variance

19

## within group variance

### variance between members of the category on a given continuous variable

20

## between group variance

### differences in the grand mean and group mean for each group

21

## f-statistic (ANOVA)

### a ratio for the within-groups variance to the between-groups variance

22

## what does it mean if the f-statistic is 0 (ANOVA)?

### the means for between-group and within-group variance are the same

23

## ANOVA assumptions

###
independent observations

normal distribution

homogeneity of variance

80+ observations

24

## p-value

### exact probability of getting computed test statistic that is due to chance

25

## assumptions of chi-squared

###
both variables are categorical

expected count is more than 5

26

## coding for nominal/ ordinal/ interval data

###
1,2,3,4, etc

male = 1, female = 2

27

## coding for ratio data

###

40yrs old

28

## coding for missing data

### -99
