Candy Connection

Mr. Lehman wanted to know __whether or not__ his __students__ __would do better on a quiz__ if he __promised__ them __candy__. He went to the library and read several studies about the effect of giving food to lab animals. He found out that if animals were given food as a reward for doing something, they usually did better the more reward they were given. He guessed that the more candy that his students were promised, the better they would do on the quiz. He had all of his classes participate in the experiment. There were four groups. Each group had the same amount of boys and girls, they were all given the __same quiz__, they were all the __same__ __age__, the __same ability__, and they were all from the __same__ __background.__ The __first group__ was __not promised__ any __candy__ if they did well on the quiz. The __second group__ was promised __1__ __candy bar__ if they did well on the quiz. The __third groups__ was promised __2 candy bars__ if they did well on the quiz. The __fourth group__ was promised __3 candy bars__ if they did well on the quiz. See the data table below for the results of this experiment:
 * = Group ||= # Promised Candy Bars ||= Test Average ||
 * = 1 ||= 0 ||= 70% ||
 * = 2 ||= 1 ||= 80% ||
 * = 3 ||= 2 ||= 90% ||
 * = 4 ||= 3 ||= 95% ||

Complete each of the following:
 * 1) Identify the hypothesis: Kids will do better on tests if they recieve candy as a reward for doing good.
 * 2) Identify the independent variable: amount of candy bars
 * 3) Identify the dependent variable: students grades
 * 4) Identify the other variables Mr. Lehman needs to consider/control during this experiment: kind of candy bar, size of candy bar, size of the students, what time of day, length of the test, the age of the candy bar, the amount of sleep they receive, how much food did they eat before, what subject is the test on, being observed by a teacher or not, size of the room ( someone may be closterfobic ), if the children like candy bars.
 * 5) Identify the control group in this experiment: the students not receiving candy bars
 * 6) Identify the experimental group(s): the students receiving the candy bars
 * 7) What conclusions might be drawn from this data? the kids that received the most amount of candy bars did the best on the test.
 * 8) What recommendations might you suggest for further study or for improvement? the length of the test maybe could be longer or shorter. Giving the kids the same amount of food before the test. The kids health. The mood of the kids. the temperature of the room ( the room temperature may affect how active the kids are ).
