Simple Linear Regression, Example research scenario: Is there a…

- - - - review them
        
        NOW, look for your assumption:
        
        is there a linear relationship?
        
        go to 'plots'
        
        click on 'scatter plots'
        
        deselect ALL the 'histogram'
        
        also deselect the 'add regression line'

  - - - move over the predictor variable first
        
        then move over the outcome (predicted) variable
        
        select 'pearsons r'
    - - Select 'linear regression'
        
        mental note: 'dependent variable section' = coutcome variable
        'covariates' = predictor variable
        
        put the outcome variable in the 'dependent variable'
        
        Put the predictor variable in the 'covariates'
        
        Don't look at the tables for now, test for the assumptions

        2. are residuals normally distributed?
