Question 48

Let's read the following scenario and match each statement with the correct answer. Mr. Marsden was interested in finding the fastest way to get to school. He decided to compare the time of his normal route to school (A), with the other two possible routes he could take (B and C). His hypothesis was that if he took route B, then he would arrive at the school with the fastest average time. Each time Mr. Marsden traveled the routes, he made sure to drive the same speed, same car, and was the only car on the road. The only difference in the experiment was the actual route chosen to school. The data was recorded and written down and recorded as minutes. Route A Route B Route C Try 1 6.1 7.4 4.5 Try 2 7.3 5.4 8.1 Try 3 6.2 6.7 6.3 Average 6.53 6.5 6.3

Answer 48

The control was __________. Route A The independent variable was ________. Different routes The dependent variable was ________. Average time to school The hypothesis was ________.
