There must be at least
three data points in
the data set for the
SKEW function.
SLOPE returns the slope of the regression line through data points in known_y’s and
known_x’s .
The slope of line is the vertical distance divided by the horizontal distance between any two
points on the line. Figure 11.43 shows the result of calculating the slope for a set of sales data.
KNOWN_Y’S Is the set of data points or values; the dependent variable.
KNOWN_X’S Is the set of independent data points.
The equation for the slope of the regression line is
Figure 11.43
The slope of a line is
the amount of change
in y due to a change of
one unit in x.
