Classroom: Error: Relative Error: You measure the classroom to be 30.5 ft long. You measure your desk to be 2.5 ft wide. The classroom is actually 31 ft long and the desk is 2 ft wide. Calculate the relative errors to the nearest tenth of a percent. Which measurement had less relative error? Less Relative Error ft % Error: Relative Error: Desk: Less Relative Error ft % 120 people Relative Error: Two surveys are conducted. In both surveys 24 forms are filled out incorrectly. If one survey included 120 people and the other survey included 8,000 people, calculate the relative errors to the nearest tenth of a percent. Which survey had less relative error? Less Relative Error % Relative Error: 8,000 people Less Relative Error % Pencil: Error: Relative Error: You measure your pencil and find that it is 7.5 cm long, but it is really 8 cm long. You measure your desk and find that it is 83.1 cm wide, but it is really 82.6 cm wide. Calculate and compare the relative errors of both measurements, round to the nearest tenth of a percent. Less Relative Error cm % Error: Relative Error: Desk: Less Relative Error cm % 400 people Relative Error: Two surveys are taken on the same topic. The first survey included 400 people. The second survey included 3,500. In both surveys, 22 people’s responses were not counted because they filled out the form incorrectly. Calculate and compare the relative errors of both surveys, round to the nearest tenth of a percent. Less Relative Error % Relative Error: 3,500 people Less Relative Error % Pencil: Error: Relative Error: You measure your cell phone and find that it is 9.7 cm long, but it is really 10.5 cm long. You measure your table and find that it is 73.1 cm wide, but it is really 72.3 cm wide. Calculate and compare the relative errors of both measurements, round to the nearest tenth of a percent. Less Relative Error cm % Error: Relative Error: Desk: Less Relative Error cm % 5,000 people Relative Error: Two surveys are taken on the same topic. The first survey included 5,000 people. The second survey included 300. In both surveys, 19 people’s responses were not counted because they filled out the form incorrectly. Calculate and compare the relative errors of both surveys, round to the nearest tenth of a percent. Less Relative Error % Relative Error: 300 people Less Relative Error % Table: Error: Relative Error: You measure your table and find that it is 70.1 cm long, but it is really 71 cm long. You measure your marker and find that it is 6.4 cm wide, but it is really 5.5 cm wide. Calculate and compare the relative errors of both measurements, round to the nearest tenth of a percent.
