Verified step by step guidance1
Understand the concept of correlation: Correlation is a statistical measure that describes the extent to which two variables are related. It can be positive, negative, or zero.
Identify the relationship described: The problem states that as the number of hours spent watching TV increases, students' grades decrease.
Determine the type of correlation: A negative correlation occurs when one variable increases while the other decreases. In this case, more TV hours lead to lower grades.
Consider the options provided: The options are positive, negative, mild, and parametric. A positive correlation would mean both variables increase together, which is not the case here.
Conclude the type of correlation: Based on the relationship described, the correlation between TV hours and grades is negative, as an increase in TV hours is associated with a decrease in grades.
