STEP 1:
• State the hypotheses
Null hypothesis • denoted by H0 • a statement that the value of a population parameter is equal to some claimed value • the prediction that there is no interaction between variables
Alternative hypothesis • denoted by H1 or Ha or HA • a statement that the parameter has a value that somehow differs from the null hypothesis • the prediction that there is a measurable interaction between variables
