Question

Directions: Answer the questions about the following scenarios.

Scenario: Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and

assigns each group 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.

Questions:

Identify the:

1) Control group

2) Independent variable

3) Dependent variable

4) What should smithers conclusion be?

Make sure to explain why each answer is it's answer. Like I said before I don't want you doing my homework for me. I want it explained to me.

Thanks.

Answer 1

1. group b, this group is the normal circumstance, and was not altered in any way

2. special juice, nothing effected the amount of juice or where it was given, it was added into the experiment

3. papers stapled, this product was affected by the special juice, and thus, depended on that for its outcome.

4. smithers conclusion should be that the special juice, instead of increasing productivity, slowed it down. this can be concluded because group a, with the special juice, accomplished less in the same amount of time as group b, which did not have the special juice.  

Answer 2

Alright, first of all. I would suggest trying to get a study group together with friends or speaking to a teacher. You will often find that people who don't know what they are talking about will try to explain things to others.

The control group is group B, this is because they were left to their own devices and were not given any juice.

According to marketresearchterms.com, the independent variable is the variable that is controlled by the researcher. Therefore, the independent variable in this case is the juice.

The dependent variable is the party/organism/thing that depends upon the independent variable to change, the dependent variable is therefore Group A.

The logical conclusion here would be that the juice does not increase the productivity of workers because the group given the juice did not form more stacks than the control group.

That's the best that I can do for you, and I hope that if you are taking a chemistry course you enjoy it. I sure did.

Answer 3

1) The control group is Group B because it wasn't given any of the juice, Group B is only used to compare to the results of Group A.

2) The juice is the independent variable, because it is the variable that is manipulated(only given to one group) and because it is the variable you are testing.

3)The dependent variable is the stacks of papers because that is what you are measuring.

4) Smithers conclusion would then be that the juice does not increase the productivity of workers, because Group B did more work than Group A.
