Answer & Explanation
Verified Solved by verified expert

ANOVA refers to a statistical model of separating the variances in a set of data for utilization in the additional tests.

Step-by-step explanation

ANOVA is useful in comparing the differences that might arise in studying the differences in a set of data. It identifies the variance and the sources within groups.

ANOVA is done in two ways: one way and two way. The two way is done using or without replication. The one-way model is used to test the differences between the two groups.

ANOVA works in the form that closely examines the variations within a group and the variations between groups.

In studying the impacts of health education initiatives in a country, the one-way method in ANOVA is the best choice because it involves seeking differences that exist in one continuous variable in one group variable, which is the education initiatives.
