In order to test the effectiveness of the debate of the candidates for the president, researchers randomly contacted 1000 people

on the phone. An attempt was made to contact all 1000 one day before the debate and ask their voting intentions. Only 910 were actually reached by phone; 80 out of the 910 people refused to participate. One day after the debate, 810 of the 910 people were reached and again asked their voting intentions. In addition they were asked if they had seen the debate on television. The before-after change of the viewers and non-viewers were compared to conclude which candidate was more effective in the debate. What kind of experimental design is being used? Describe relevant potential extraneous variables in this experiment. Can this experiment design rule out these extraneous variables?

The results of bhalla and proffitt's (1999) physical-fitness-and-hill-steepness study demonstrated that
TEA [102]
<span>c. less physically fit individuals perceived the hill as being more steep. The 1999 study "Visual-Motor Recalibration in Geographical Slant Perception" by Mukul Bhalla and Dennis R. Proffitt showed the results of 4 experiments. These experiments showed that people who are wearing a heavy backpack, or who are fatigued, or who have low fitness, or who are elderly or unhealthy consistently perceived hills as being steeper than they really are. So with that in mind, let's look at the available options and pick the correct one. a. individual fitness level does not affect perception of hill steepness. * This is in direct conflict with the study, so it's wrong. b. fit individuals perceived hills as being more steep because they were fatigued. * It's true that fatigued people perceive the hills as being steeper, but fatigue isn't an effect of being fit. So this too is a bad choice. c. less physically fit individuals perceived the hill as being more steep. * This agrees precisely with experiment #3 of the paper. So this is the correct choice. d. none of these. * Since choice "c" above has been selected, this is obviously incorrect.</span>
