Answer:
-0.9
Step-by-step explanation:
my guess
it's supposed to be the a number closest to 1 or-1
so
-0.9 is the closest number to 1 or -1
The answer to this question is:
0.8
What is line of best fit and correlation coefficient?
A straight line that best approximates the given set of data is known as a line of best fit. It is a line that, on a graph, roughly straddles the center of each scatter point. The association is stronger the closer the points are to the line of greatest fit.
The equation of a line of a best fit is represented as: y=mx + c
To gauge how closely two variables are related to one another, correlation coefficients are used.
Solution:
In order to determine how closely related two sets of data are, correlation coefficient formulas are used. The formulas provide a value in the range of -1 and 1, where
- 1 denotes a strongly positive association.
- A score of -1 indicates a very adverse association.
- A result of zero means there is absolutely no association
The strength of the link between the variables increases with the distance between the coefficients of +1.0 and -1.0.
-0.9 is a value which is greater than -0.8, so the values which are greater than -0.8 are not considered as strong correlation coefficient.
Whereas the values which are less than 0.8 are also not considered as strong coefficients.
Hence 0.8 is the correlation coefficient which represents the strongest linear relationship.
