  1. ANOVA is a test to find out that if a survey or experimental results are significant.
    Basically, you are testing groups to see if there is any difference between them.
    Example :
    A group of psychiatric patients are trying three different therapies:
    conseling, medication and biofeedback. You want to see if one therapy is better
    than other.

    One-way or two-way ANOVA refers to the number of independent variables in your
    analysis of variance test. One-way has one independent variable(with 2 levels) &
    two-way has 2 independent variables(can have multiple levels). Group or levels
    are different groups in the same independent variable.
