Question

Image that a researcher examined how the people’s weights affect their salaries. She found that the correlation between weights (measured in lbs.) and salary range (measured in dollars) was .10. Had she measured the weight in kg instead, what would the correlation have been?

a. Above 0.10

b. Below 0.10

c. 0.10

Answer 1

Answer

Option C is correct

There will be no change in the correlation coefficient because when we convert one variable from one unit to another unit, then there will be some fixed change in each data value of that particular variable

We use the standardization technique to find the standard value corresponding to each raw value, this helps in reducing the affect of change in units.

Therefore, we have absolutely no change in the correlation coefficient value and it will remain same.

option A and B are incorrect because correlation coefficient is neither decreased nor increased, but it remains same
