Collecting Design Test Data Practice Test

At the science center, Sofia and Amir had a problem: they could not reach a high shelf. They built two platforms. Design A was a short box, 3 inches high. Design B was a tall box, 6 inches high. When they tested the designs, they did the same test each time: one student stood on the platform and reached up, then they measured the height reached with a tape measure. They collected data in inches. Results: Design A reached 48 inches, Design B reached 51 inches. They wrote the numbers in a list. What did they measure during the tests?

In engineering time, Yuki and Marcus had a problem: water spilled when pouring into a bottle. They made two funnel designs. Design A had a wide opening. Design B had a narrow opening. When they tested the designs, they poured 1 cup of water through each funnel into the same bottle. They collected data by measuring spilled water in tablespoons. Results: A spilled 2 tablespoons, B spilled 5 tablespoons. They wrote the numbers in a list. How did testing help them compare the designs?
