Question 14 • (AG Q4) Math 8: 25-26 (JTurner)

Nicole is studying a two-way table. She has computed the relative frequencies by column for each cell. What characteristic of the data will imply an association between the two variables?

Answer
A
The relative frequencies are nearly the same in each row.
B
The relative frequencies are significantly different each row.
C
The relative frequencies add to 100% for each column.
D
The relative frequencies add to 100% for each row.

Explanation

When relative frequencies are calculated by column, compare the values across columns for each row. If the row’s relative frequencies differ significantly from one column to another, the distribution of one variable depends on the other, indicating an association. Nearly identical relative frequencies would instead suggest little or no association.
