Question

mrs. nygaards class has 12 boys and 14 girls. she asked the class members if they prefer a field trip to the local zoo or to an aquarium. she set up a two - way table to summarize the results. which could describe the row and column headings for mrs. nygaards table?

• gender and field trip preference
• gender and number of students who prefer the aquarium
• number of boys and number of students who prefer the aquarium
• number of girls and field trip preference

Explanation:

A two-way table summarizes two categorical variables. Here, the two distinct categorical groups are student gender (boys/girls) and their field trip preference (zoo/aquarium). The other options either use a single preference category or a count as a heading, which does not fit a two-way table structure.

Answer:

gender and field trip preference
