Start here with your data


Univariate statistics

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

Do you have several continuous variables without clear dependencies?


Categorical and continuous data

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


Does you categorical variable only contain two groups
Does you categorical variable contain more than two groups


More than 2 categorical variables

Analysis of Variance

Dependent variable normally distributed

INSERT TYPE II
Linear mixed effect model

Dependent variable not normally distributed

Type III Anova

Dependent variable is count data

Dependent variable is 0/1 or proportions

Random factors

t-test

My data consists only of categorical variables

Chi-Square test

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
