Dr. Nguyen is studying the emotional effects of watching television (TV) news. After taking a pretest measuring mood, each of the 200 college students in her sample is randomly assigned to watch fifteen minutes of either good news on TV, bad news on TV, a funny TV show, or no TV
at all. Her participants then complete an identical posttest measure of mood that they completed at pretest. Results of her research appear in the graph. Consider all of the differences between bar heights to be significant.
Which of the following would be accurate conclusions from her research?
Watching TV caused the tested college students' moods to change.
Watching good news on TV causes the tested college students' mood to increase.
If parents show their children a funny show before bed, it will cause the childrens moods to decrease.
Watching a funny show caused the tested college students' moods to decrease.
Mikey had two mice that were about the same age and weight. Mikey fed each of the two mice a different feed for a month. He measured how much the mice weighed every two days until the month was over. Mikey's results showed that although both mice gained weight over the month, mouse 2 gained more weight than mouse 1.Which graph below best shows these results?
You decide to clean your bedroom. You notice that your floor is covered with clothes. You decide to try to get rid of the clothes by throwing the clothes into the air. You throw clothes from 1/3 of the room into the closet and a second 1/3 of the room straight up in the air. In the last 1/3 of the room, you leave the clothes on the floor. After 30 minutes of "cleaning", the floor of the room is now visible.

A biologist hypothesizes that a squirrel's body size is affected by the inclusion of a particular type of food in its diet. Which is the best method the scientist could use to prove this hypothesis?
Collect data by observing the squirrels eating food in the wild.
Design a controlled experiment to test different types of food.
Set up the experiment with squirrel's of the same type, body size and age and test the body size before and after the different types of foods are used.
Develop a theoretical model to predict how the food type will affect body size

An experiment was carried out to determine whether drinking caffeinated soda increases pulse rate. The pulse rates of two groups of people at rest were measured. Group A was then given caffeinated soda and group B was given caffeine-free soda. One hour after drinking the soda, the pulse rates were measured. The participants in the experiment were all the same age, and they were all given the same amount of soda.
