CHI SQUARE TEST
CHI-SQUARE GOODNESS-OF-FIT TEST (only one category)
CHI-SQUARE TEST OF INDEPENDENCE (two categories)
Condition:
1. Use only absolute frequencies (not percentage) in the calculation.
2. Make sure that each individual is included in only one category
3. Check that all expected frequencies are at least 5.
When the data is about small sample or there is no homogeneity of variance between groups.
1. CHI SQUARE
condition: one sample one test
X2(2)=20.6, p<0.05
1. df=r-1
2. p value
3. two tailed test only
p.188-189
1. BIVARIATE CORRELATION
To test correlation ship between two variables
2. REGRESSION EQUATION
Line of best fit and Standard error of estimates
Y'=bX+a
Multiple regression: when you determine to include multiple independent variables, be sure of the correlation between each independent variable and dependent variable, and the independence between every pair of independent variables.
