Four students in ms. alton's class shared the correlation coefficients derived from their data as follows: student a: r = –0.87 student b: r = –0.78 student c: r = 0.79 student d: r = 0.86 whose data had the strongest correlation?

answer: student a: r = –0.87

step-by-step explanation:

we know that the closer the value is to 1 or –1, the stronger the linear correlation.

from all the options, student a with correlation coefficient r = –0.87 is nearest to -1 ,had the strongest negative correlation.

correlation tells that the strength of a relationship between two variables .

a strong, or high, correlation means that two or more variables have a strong relationship with each other.

a weak or low correlation means that the variables are hardly related.

the aswere is the one with all 8's and the second one is with the 10,8 and 6
