Experiments are more valuable than other research methods because:

Psychologists sometimes prefer to make observations in a laboratory setting rather than a naturalistic setting because:

Suppose an experiment is to draw a card from a normal 52-card deck.  Determine the probability of drawing a red card or a face card.  

Refer to the following table that shows the results from a survey of 140 people at an auto mechanic shop when asked why he or she had brought in his or her vehicle.     Men Women Brakes fixed 12 5 Engine problems 25 15 Oil change 40 30 Other 8 5   Determine the probability that the person had an oil change, knowing that she was a woman  

.  Suppose an experiment is to spin the following spinner and then draw a ball from the bag with the number landed on.  Bag 1 contains 1 red ball and 9 white balls.  Bag 2 contains 2 red balls and 8 white balls.  Bag 3 contains 15 red balls and 1 white ball.  Bag 4 contains 19 red balls and 1 white ball. Find the probability that the selected ball was from Bag 4 and it was white.
