An initial path towards statistical analysis

Start here with your data! This is your first question.

Do you have several continuous variables without clear dependencies?
Yes! No!

Univariate statistics

No! Does you data contain at least one categorical variable?
Yes, I have at least one categorical variable! (?)
No, I have only continuous variables! (?)

Multivariate statistics

Yes!

Categorical and continuous data

Does your data consist of categorical and continuous data? Does your data consist only of categorical data?

More than 2 categorical variables

Is your dependent variable normally distributed?
Is your dependent variable not normally distributed?

My data consists only of categorical variables

Does your independent variable contain only 1 or 2 groups?
Does your independent variable contain more than 2 groups?

Does your independent variable contain more than 2 groups?

Analysis of Variance

Is your dependent variable normally distributed?
Is your dependent variable not normally distributed?

The dependent variable is normally distributed

Dependent variable normally distributed

Random factors

Dependent variable not normally distributed

Random factors

Does your independent variable contain more only 1 or 2 groups?

t-test

My data consists only of categorical variables

Continuous variables

Non dependent relations? Correlations

Clear dependent relations Regression models
Dependent variable normally distributed
Linear Regression

Dependent variable not normally distributed

Generalised linear model

Dependent variable is count data

Dependent variable is 0/1 or proportions

Multivariate statistics
