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!

R commands:
Relevant figures:

Univariate statistics

Does you data contain at least one categorical variable?
Yes, I have at least one categorical variable! (?) (?)
R commands:
Relevant figures:

Categorical and continuous data

Does your data consist of categorical and continuous variables? R commands:
Relevant figures:

Does your data consist only of categorical variables? R commands:
Relevant figures:

Categorical variables

Chi-Square test

R commands:
Relevant figures:

Does you categorical dependent variables have 1-2 factor levels?

Does you categorical dependent variables have more than 2 factor levels?

Analysis of Variance

R commands:
Relevant figures:

The dependent variable is normally distributed

Dependent variable normally distributed
