Teenage females tend to have fewer speeding tickets than teenage males. c. Students with lower IQ scores tend to have lower grades. d. As hours studying for a test decrease, so do grades on that test. e. Students’ shoe sizes are not related to their grades.

Answer 1

Answer:

a. People who spend more time exercising tend to weigh less.          

Explanation:

In psychology, there are two different types of correlation exists including a negative and a positive correlation.

A negative correlation is described as a relationship that generally exists between two different variables whereby one variable increases and the other variable tends to decrease, and vice-versa. A perfect 'negative correlation' is signified by the value of '-1'.

Answer 2

The one that exemplifies a negative correlation would be:

a). People who spend more time exercising tend to weigh less.          

• Correlation is described as the complementary association that exists between two variables or situations.
• A positive correlation implies that an increase in one variable causes the increases of the other.
• While in negative correlation, a -ve change in one variable causes the other to change in -ve or reduce.
• The situation of people who spend more time in exercise having lesser weight(increase in one causes a decrease in other) exemplifies negative correlation effectively.

Thus, option a is the correct answer.
