Returns the slope of the linear regression line through data points in known_y's and known_x's. The slope is the vertical distance divided by the horizontal distance between any two points on the line, which is the rate of change along the regression line.
Syntax
SLOPE(known_y's,known_x's)
Known_y's is an array or cell range of numeric dependent data points.
Known_x's is the set of independent data points.
Remarks
- The arguments must be either numbers or names, arrays, or references that contain numbers.
- If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
- If known_y's and known_x's are empty or have a different number of data points, SLOPE returns the #N/A error value.
- The equation for the slope of the regression line is:
where x and y are the sample means AVERAGE(known_x’s) and AVERAGE(known_y’s).
