Question

Mr. Jones, a sixth grade science teacher, has tried to predict his students’ end-of-the-year grades by looking at their end-of-the-year grades from the previous year. Unfortunately, there does not seem to be any systematic relationship between these two variables. The correlation between these two variables is probably
a.near zero.
b.positive.
c.negative.
d.near 1.0.

Answer 1

Answer: The correlation between between the two variable is probably "NEAR ZERO". Which means option "a" is the most correct option.

Explanation: Systematic relations is the orderly arrangement of different values in ascending or descending order. It is a way different values or things are related to each other.

For a two value to have slight chance or no chance of being systematically related it means, the difference between the value is zero or near zero.

Systematic relation is zero when the two values are the same. It is near zero when the difference between the two values is in decimal near zero. It is positive when the difference are positive. It is negative when the difference are negative, it is near 1 when the difference are is more than zero, that means it can be related systematically.

Because they doesn't seem to be any systematic relation between the two, that means the difference between the two values is near zero.
