Null hypothesis
This states that NO real relationship or difference exists between the independent and the dependent variables. Any relationship between the two variables is merely due to chance or error.
Null hypothesis is denoted as Ho. Mathematically, it is represented as: H0: µ1=µ2
Alternative hypothesis
The opposite of null hypotheses; they tell us that a relationship exists between the independent and the dependent variables.
It is a prediction that an experimental manipulation will have some effect or that certain variables will relate to each other.
Also called the research hypotheses because they are the ones the researcher sets.
Mathematically, it is represented as;
H1: µ1?µ2 (non directional) or
µ1>µ2 (directional) or
µ1<µ2 (directional)
