Formula & Methodology
The trend analysis calculator uses linear regression to fit a line through the data points. The formula for the trend line is:
y = mx + b
where ‘m’ is the slope of the line, ‘b’ is the y-intercept, and ‘x’ is the independent variable (time in years).
Real-World Examples
Example 1: A company’s sales over four years are 100, 120, 115, and 130 million dollars. Using the calculator, we find the trend line equation is y = 5.25x + 97.5. This means that, on average, sales increase by 5.25 million dollars each year.
