Start here with your data

Do you have several continuous variables without clear dependencies?
Yes-> Multivariate statistics
No-> Univariate statistics


Univariate statistics

Categorical and continuous data (?)
Only continuous variables (?)
Only categorical variables (?)

Categorical and continuous variables

[[At least one continuous and one categorical variable|

     More than 2 groups

Analysis of Variance
Dependent variable normally distributed
INSERT TYPE II
INSERT RANDOM FACTOR
INSERT LMM

Dependent variable not normally distributed

Type III Anova

Dependent variable is count data

Dependent variable is 0/1 or proportions

Random factors


Only categorical variables

Chi-Square test

Only continuous variables


Non dependent relations
Correlations 
Clear dependent relations
Regression models
 Dependent variable normally distributed
  Linear Regression 
Dependent variable not normally distributed
 GLM 
Dependent variable is count data
  Poisson GLM 
 Dependent variable is 0/1 or proportions
 Binomial GLM 











Multivariate statistics
