Understanding Correlation and Causation

What type of correlation does this scatter plot show?

• positive linear association

• negative linear association

• no association

• nonlinear association

Choose the correlation coefficient that best matches the graph.

• -1

• 0

• 0.5

• 1

Describe the relationship between the variables.

• A) Weak positive correlation

• B) Weak negative correlation

• C) Strong positive correlation

• D) Strong negative correlation

What type of correlation does the graph show?

• Positive Correlation

• Negative Correlation

• No Correlation

Which of the following best describes a positive correlation?

• As one variable increases, the other variable decreases.

• As one variable increases, the other variable also increases.

• There is no relationship between the two variables.

• One variable causes the other to change.

What does a scatter plot with points closely clustered around a line with a negative slope indicate?

• No correlation

• Positive correlation

• Negative correlation

• Causation

Which of the following statements is true about correlation and causation?

• Correlation always implies causation.

• Causation always implies correlation.

• Correlation never implies causation.

• Causation never implies correlation.

If a scatter plot shows a random distribution of points with no discernible pattern, what type of correlation is present?

• Positive correlation

• Negative correlation

• No correlation

• Perfect correlation

Which of the following scenarios best illustrates a false causation?

• Increase in coffee consumption and rise in productivity

• Rise in smartphone usage and decrease in physical activity

• Number of storks and birth rates

• Amount of study time and exam scores

In a scatter plot, what does it mean if the points form a perfect straight line?

• There is no correlation.

• There is a perfect correlation.

• There is a weak correlation.

• There is a causal relationship.
