BCR(brief constructed response)? - brief constructed response
13. In a television interview as a guest so that people who are vigorously exercise for 15 minutes or more each day to be able to solve mathematical problems faster than those without intense exercise into your daily routine.
Describe a controlled experiment that has been undertaken in order to able to prove this assertion. In his presentation, you must:
State • The purpose of the experiment
State • Why is the sample must be as large
• Describe were treated as the experimental group and treated as the control group

Let's go the next 100 at a gym and exercise daily for 2 weeks, was determined by the school principal. After two weeks in order to undergo a test of math 1 minutes from the simple addition and subtraction. See how much you do in a minute, taking into account the problems of maximum capacity of 500
As a control, use the 100 people admitted in an office that they are sedentary. Click on the same test and score tests.
Objective: To compare the test results for mathematics acceleration sedentary and active adults the same age.
Must be great to get a good statistical sample.
See above.
Specific data: Record of the Year (15 minutes per day?) And the number of problems correctly completed in one minute
If the number of problems in the experimental group was significantly higher than the number in the control group using the chi-square test.
