Arecent article in an educational research journal reports a correlation of + 0.8 +0.8 between math achievement and overall math aptitude. it also reports a correlation of − 0.8 −0.8 between math achievement and math anxiety. which of the following interpretations is the most correct? a. the correlation of + 0.8 +0.8 indicates a stronger relationship than the correlation of − 0.8 . −0.8. b. it is impossible to tell which correlation is stronger. c. the correlation of + 0.8 +0.8 is just as strong as the correlation of − 0.8 .

C. The correlation of + 0.8 +0.8 is just as strong as the correlation of − 0.8 .

Correct. Both correlation coefficients+0.8 and -0.8 indicates strong relationship, the only difference is that the +0.8 is associated to a proportional relation and the value of -0.8 to an inverse proportional relation. But when we want to see if a correlation value is strong we need to analyze the absolute value and if we satisfy that the absolute value is near to 1 we have strong relationship.

Step-by-step explanation:

Previous concepts

The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.

And in order to calculate the correlation coefficient we can use this formula:  

Solution to the problem

A. The correlation of + 0.8 indicates a stronger relationship than the correlation of − 0.8 .

False both correlation coefficients +0.8 and -0.8 indicates strong relationship, the only difference is that the +0.8 is associated to a proportional relation and the value of -0.8 to an inverse proportional relation. But when we want to see if a correlation value is strong we need to analyze the absolute value and if we satisfy that the absolute value is near to 1 we have strong relationship.

B. It is impossible to tell which correlation is stronger.

False we can conclude soomething about the statement.

C. The correlation of + 0.8 +0.8 is just as strong as the correlation of − 0.8 .

Correct. Both correlation coefficients+0.8 and -0.8 indicates strong relationship, the only difference is that the +0.8 is associated to a proportional relation and the value of -0.8 to an inverse proportional relation. But when we want to see if a correlation value is strong we need to analyze the absolute value and if we satisfy that the absolute value is near to 1 we have strong relationship.

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

3750 deer

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol
