Ch1 Scientific Thinking

Question 1

Do you know for certain that a controlled experiement’s test group with positive correlations are positively caused by the hypothesis?

Answer 1

Yes.
Because the control group accounts for all other explanations. Each group has been exposed to the same conditions except the independent variable (the one that we manipulate).

Question 2

What are confounding variables?

Answer 2

Something else that could explain your result. Such as the design of the particular researcher. So a good design would account for that and and the findings were not exclusive to a particular persons study

Question 3

Which variable do we measure?

Answer 3

The depending variable.
(The effect).

The independent variable is the cause.

Question 4

We manipulate the independent variable to show that is has and effect on ______?

Answer 4

The dependent variable.

Question 5

What three things do you have to have to demonstrate causation?

Answer 5

-Correlation.
(There can be no cause without correlation)
-A time order effect.
(If you think a causes b then a has to happen before b. The cause has to come first!)
-You have to rule out every other possible cause.
(Control group gives you every other cause to be ruled out!)

Question 6

When you find a strong correlation between two variables, how do you discover the cause?

Answer 6

Conduct an experiment with a test group and a control group to see if your hypothesis is supported.
