What kind of analysis would be best to conduct If your independent variable was a 3 level categorical variable and your dependent variable was a continuous variable?
However, If the dependent variable is not normally distributed and you have a categorical independent variable is paired then you use WILCOXON SIGN RANK TEST. If the dependent variable is normally distributed and you have a categorical independent variable that has 3 or more levels then you use ONE WAY ANOVA.
Which analysis should be used if you are testing for relationships between three or more categorical variables?
A chi-square test is used when you want to see if there is a relationship between two categorical variables. In SPSS, the chisq option is used on the statistics subcommand of the crosstabs command to obtain the test statistic and its associated p-value.
Can there be three independent variables?
In practice, it is unusual for there to be more than three independent variables with more than two or three levels each. This is for at least two reasons: For one, the number of conditions can quickly become unmanageable.
What are the levels of independent variable?
If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: experimental and control. If an experiment were comparing five types of diets, then the independent variable (type of diet) would have 5 levels.
How is the means of a continuous variable determined?
statistical analysis of continuous variables requires the application of specialized tests. In general, these tests compare the means of two (or more) data sets to determine whether the data sets differ significantly
How to choose a statistical test for one dependent variable?
Choosing a Statistical Test This table is designed to help you choose an appropriate statistical test for data with one dependent variable. Hover your mouse over the test name (in the Test column) to see its description. The Methodology column contains links to resources with more information about the test.
When to use independent samples in statistical analysis?
An independent samples t-test is used when you want to compare the means of a normally distributed interval dependent variable for two independent groups. For example, using the hsb2 data file, say we wish to test whether the mean for write is the same for males and females. t-test groups = female (0 1) /variables = write.
Which is an example of an independent variable?
Example independent variables that meet this criterion include gender (two groups: male or female), ethnicity (three groups: Caucasian, African American and Hispanic), profession (five groups: surgeon, doctor, nurse, dentist, therapist), and so forth.
