Question

smithers thinks that a special juice will increase the productivity of workers. he creates two groups of 50 workers each and assigns each group the same task (in this case, theyre supposed to staple a set of papers). group a is given the special juice to drink while they work. group b is not given the special juice. after an hour, smithers counts how many stacks of papers each group has made. group a made 1,587 stacks, group b made 2,113 stacks. identify the: 1. control group: ______ 2. independent variable: ____ 3. dependent variable: ____ 4. what should smithers conclusion be? ____ 5. how could this experiment be improved? ______

Explanation:

1. The control group is the group not receiving the treatment (special juice), so it's Group B.
2. The independent variable is what is being changed or manipulated, which is the special - juice (presence or absence).
3. The dependent variable is what is being measured, here it's the number of paper - stacks made.
4. Since Group B made more stacks than Group A, the conclusion is that the special juice did not increase productivity.
5. It could be improved by increasing the sample size, controlling for other factors like workers' experience, and repeating the experiment multiple times.

Answer:

1. Group B
2. Special juice (presence or absence)
3. Number of paper - stacks made
4. The special juice did not increase productivity.
5. Increase sample size, control for other factors, repeat the experiment multiple times.
