Start here with your data

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


Univariate statistics

At least one categorical independent variable

Categorical and continuous data


Analysis of Variance 
  Dependent variable normally distributed
   More than 2 groups
    Type II Anova 
     Random factors
       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
       Generalized linear mixed effect models 
   

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
