ANOVA
group of statistical techniques used to analyze experimental designs
3 Types of Experimental Designs:
Complete Randomized Design:
subjects are assigned randomly to treatments; single independent variable
3 Types of Experimental Designs:
Randomized Block Design:
includes a blocking variable – single independent variable
3 Types of Experimental Designs:
Factorial Experiments
two or more independent variables are explored at the same time; every level of each factor are studied under every level of all other factors
Completely Randomized Design:
contains only one independent variable with two or more treatment levels
CRD:
analyzed by one way ANOVA
ANOVA
null hypothesis: all pop means for all treatment levels are equal
(Ho: u1=u2=u3=u4 /// Ha: at least one of the means is different from the others )
