Understanding Negative Correlation Concepts

The video tutorial explains the concept of correlation using the example of speed and time to reach a destination. It describes how an increase in speed results in a decrease in travel time, illustrating a negative correlation. The tutorial further explains that negative correlation occurs when two variables move in opposite directions. It also demonstrates how to graph this relationship, showing a negative slope on the graph.

What happens to the time taken to reach a destination as speed increases?

• Time fluctuates

• Time remains constant

• Time decreases

• Time increases

What type of correlation is demonstrated when two variables move in opposite directions?

• Neutral correlation

• Negative correlation

• Positive correlation

• No correlation

In a negative correlation, if one variable increases, what happens to the other variable?

• It becomes unpredictable

• It remains the same

• It decreases

• It increases

How would a graph of a negative correlation appear?

• With a positive slope

• With a negative slope

• As a horizontal line

• As a vertical line

What is the slope of a line representing a negative correlation?

• Positive

• Negative

• Zero

• Undefined
