SLOPE

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:

  

Example

SLOPE({2,3,9,1,8,7,5},{6,5,11,7,5,4,4}) equals 0.305556
