Talking about the setting of data in a chi-square test at SPSS:
In raw scores, the sample number has to be equal to the number of raws
When setting data, we always work with two nominal variables
Data could be organized in raw scores, frequency distribution or net scores
At freq. distrib. we work with 3 variables in which one is always Frequency
2
The Chi-Square test is typically used to analyze the relationship between two variables under which condition?
It is the sum of positive numbers and therefore must be positive
The two variables have been measured on the difference on each variable
The observations on each variable are between- subjects in nature
Both variables are qualitative in nature (mesured on nominal level)
3
Running the chi-square test at SPSS…
This steps are correct: Statistics> Chi square, phi and lambda > Continue
At crosstabs step it doesn't matter where we put the variables.
At crosstabs step, it really makes a difference where we put the variable
This steps are correct: Analyze>Descriptive Statistics>Descriptives
4
Which two p-values are the most significant?
p=0,045
p=0,09
p=0,0005
p=0,1
5
What do you have to report after doing a chi-square test?
The t-value
The value in reference to a single variable
The value in relation between two test variables
The significance value
6
What is not true about the use of Fisher´s Exact test?
To compute when the expected frequencies are more than 5
To compute the exact probability of the chi-2 statistic in small samples
To determine if there are nonrandom associations btw 2 cat. variables
It relies on an approximation and ignore whether it is positive or negative
7
If the p-value is smaller than the significance level, the Null Hypothesis can be:
Concluded that the effect is statistically significant
Accepted
Declared that the effeect is not statistically significant
Rejected
8
Logliner analysis examines the relationship of…
More than two categorical variables
At least two categorical variables
One categorical variable
Only two categorical variables
9
Which are the hypothesis for the chi-square test for two-way table counts?
H0- no relationship between categorical variables
H0- relationship between categorical variables
H1- relationship between categorical variables
H1- no relationship between categorical variables
