Question

scenario c. bart believes that mice exposed to radiowaves will become extra strong (maybe hes been reading too much radioactive man). he decides to perform this experiment by placing 10 mice near a radio for 5 hours. he compared these 10 mice to another 10 mice that had not been exposed. his test consisted of a heavy block of wood that blocked the mouse food. he found that 8 out of 10 of the radiowaved mice were able to push the block away. 7 out of 10 of the other mice were able to do the same. identify the: 1. control group: 2. independent (manipulated) variable: 3. dependent (responding) variable: 4. what should barts conclusion be? 5. how could barts experiment be improved?

Explanation:

1. The control group is the group not exposed to the variable being tested. Here, it's the mice not exposed to radiowaves.
2. The independent variable is what the experimenter changes or manipulates. In this case, it's the exposure to radiowaves.
3. The dependent variable is what is being measured or observed. Here, it's whether the mice can push the block away.
4. Bart should conclude that there is little to no significant difference in strength (ability to push the block) between mice exposed to radiowaves and those not exposed, based on the close - numbered results.
5. Bart could improve his experiment by increasing the sample size of mice to get more reliable results, controlling for other environmental factors that could affect the mice's strength (like diet, age), and repeating the experiment multiple times.

Answer:

1. The 10 mice that had not been exposed to radiowaves.
2. Exposure to radiowaves.
3. Whether the mice can push the block away.
4. There is little to no significant difference in the strength of mice exposed to radiowaves and those not exposed, as 8 out of 10 radiowaved mice and 7 out of 10 non - radiowaved mice could push the block away.
5. Increase the sample size of mice, control for other environmental factors, and repeat the experiment multiple times.
