Capstone CO1 Quiz

In terms of strength of association, how do you compare the Scatterplot I with II?

• The strength of association in Scatterplot I is greater.

• The strength of association in Scatterplot II is greater.

• The strength of association in the scatterplots is the same.

• The strength of association in the scatterplots cannot be compared from the information.

What is the direction of the scatter plot 1?

• Positive

• Negative

• Both A and B

• Neither A or B

What is the primary difference between a "relationship" and "correlation"?

• A relationship measures the strength of an interaction, while correlation shows if two variables change together.

• A relationship refers to a causal connection, while correlation only measures a non-causal link between two variables.

• A relationship involves two variables, while correlation only involves one variable.

• There is no difference; the terms are interchangeable.

Which of the following is true about correlation?

• Correlation shows that one variable causes the other to change.

• Correlation measures the strength and direction of a relationship between two variables.

• A correlation of 0 means that the two variables are perfectly correlated.

• Correlation can only be positive, never negative.

Which of the following is an example of a hypothesis?

• "There is a relationship between the number of hours studied and the test score."

• "The more hours a student studies, the higher their test score will be."

• "Test scores increase with more hours studied."

• "The relationship between study time and test scores is measured using Pearson’s r."

Correlation always implies that one variable causes the other to change.

• True
• False

The terms "variables" and "hypotheses" are fundamental in understanding how correlation is used in research.

• True
• False
