Question

Which r value suggests a weak positive correlation?

r=0.17454
r= -0.17454
r=0.98264
r= -098264​

Answer 1

`\boxed {\boxed {\sf A.\ r=0.17454}}`

Explanation:

The correlation coefficient helps us understand the relationship between variables.

A positive correlation is a positive number. A negative correlation is a negative number.

We can automatically eliminate choices B and D because they are negative, but we are looking for a positive correlation.

A number closer to 1 indicates a strong correlation. If the number is closer to 0, it's weak.

The two choices left are:

• A. r=0.17454
• C. r= 0.98264

C is very close to 1, so it's a strong correlation.

We want to find the weak one, which must be A because it is closer to 0.
