Answer:
the college should hire a new statistician
Step-by-step explanation:
In statistics correlation is a measure of the linear relationship between two variables.
How closely related the two variables are gives the strength of the relationship.
Positive correlation occurs when an increase in the value of one variable results in an increase in the value of the other.
Negative correlation is when there is an inverse relationship. That is an increase in one variable results in a decrease in the other.
In the given scenario where there is a statistical analysis between exam grades and scholastic achievement, the relationship between them should be a positive one.
The higher the exam grades a student gets the higher his scholastic achievement.
However it is stated that correlation is -1.08. This implies an inverse relationship, which is not correct.
So the college should hire a new statistician who can give more accurate analysis
