Making Two-Way Tables

Question 10 • PA-Common Core Math 8 Q1

Lashaun decided to create a table to compare the number of students who arrive to school by car to the number who arrive by bus. If a two-way table is made to represent the data, which could be the row and column headings?

Answer
A
column: boy, girl; row: arrive by car, arrive by bus
B
column: boy, girl; row: arrive by car, total students in class
C
column: boy, girl; row: arrive by bus, total students in class
D
column: boy, girl; row: total students in class, total who arrive by car or bus

Explanation

A two-way table compares two categories: students’ gender and how they arrive at school. The columns can be boy and girl, while the rows should be arrive by car and arrive by bus. Choice A includes both travel methods, so it can show the requested comparison. The other choices replace one travel method with a total, so they do not distinguish both groups being compared.
