When we use regression analysis, we are finding the regression equation that represents
the geometrical line that comes closest to the distribution of points. This can be
illustrated in which of the following?
a. the regression equation Y = a + bX allows us to infer values of X when we know the
value of Y
b. the regression equation Y = a + bX allows us to infer values of Y when we know the
value of X
c. the regression equation requires that we know the values of X, Y, a and b when we
begin doing the analysis
d. the regression equation has little, if anything, to do with the understanding of the
distribution of points in a data set
Which of the following is not a type of interview used in qualitative research:
a. structured
b. semi-structured
c. unstructured
d. all of these types of interviews are used in qualitative research
