Select accurate statements (no partial credit will be given).

a. an observed relationship between two variables might be the results of a third variable.

b. factor analysis is a bivariate analysis

c. correlation alone prove causality.

d. the ranges of variability on each of the two variables under study are restricted, significant correlations between the two variables are difficult to find.

e. multiple regression analysis is a multivariate analysis

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
