An important principle for understanding bivariate tables is predication error.

Question

An important principle for understanding bivariate tables is predication error. Such error is based on the differences between expected and observed frequencies. What is an expected frequency?

A. The frequencies we would expect if there were a negative relationship between the independent and dependent variables.

B. The frequencies we would expect if there were a perfect relationship between the independent and dependent variables.

C. The frequencies we would expect if there were a positive relationship between the independent and dependent variables.

D. The frequencies we would expect if there were no relationship between the independent and dependent variables.

Explanation / Answer

Expected frequency : The cell frequencies that would be expected in a bivariate table if the two tables were statistically independent.

So option D is correct.

The frequencies we would expect if there were no relationship between the independent and dependent variables.
