Question

Amani computed in a two-way table the relative frequencies of sales of homes listed with two different real estate companies.
Which statement best describes the relationship between the two variables?
A) There is an association because the relative frequencies by column are similar.
B) There is an association because the relative frequencies by row are similar.
C) There is no association because the relative frequencies by column are similar.
D) There is no association because the relative frequencies by row are similar.

Answer 1

The answer the third option.

When you look at the data, in the first column, the frequency of sales of both are similar. Even the second column shows similar data. Association is determined if there is a significant difference between the data in each column/row depending on what you are aiming to answer.

In this case, we look at it per column because you want to compare the frequencies of sales of each company which are aligned by columns. So we know to look at the columns and not the rows.
