Which of these r-value r represents the strongest correlation

A. 0.55

B. 0.65

C. 0.35

D. 0.45

0.65  represents the strongest correlation.

Option B.

Explanation:

In statistics, correlation or dependence is any measurable relationship, regardless of whether causal or not, between two arbitrary factors or bivariate information. In the broadest sense connection is any measurable affiliation, however it normally alludes to how much a couple of factors are straightly related.

For two factors, a statistical correlation is estimated by the utilization of a Correlation Coefficient, spoke to by the image (r), which is a solitary number that depicts the level of connection between two factors.

Step-by-step explanation:

The options to this question are

A. 0.55

B. 0.65

C. 0.35

D. 0.45

The correlation coefficient is a statistical measure of the realtionship between variables in a study, this measure is about how strong are realted those variables. The correlation could be strong or weak, could be negative or positive.

The range or interval where the correlation coefficent falls is from -1 to 1. If the coefficient is outside this interval, there's an error in the data set.

Now, if the coefficient is zero, it means there's no correlation between variables. But, if the coefficient is near to 1, it means the correlation is positive and strong.

Therefore, in this case, the right answer is B. 0.65, because it's the closest value to 1.

step-by-step explanation:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
