What is a trendline chart in Excel?
A trendline, also referred to as a line of best fit, is a straight or curved line in a chart that shows the general pattern or overall direction of the data. This analytical tool is most often used to show data movements over a period of time or correlation between two variables.
What does the trendline equation tell you?
Trendline equation is a formula that finds a line that best fits the data points. R-squared value measures the trendline reliability – the nearer R2 is to 1, the better the trendline fits the data.
How do you know which trendline to use?
The type of data you have determines the type of trendline you should use. Trendline reliability A trendline is most reliable when its R-squared value is at or near 1. When you fit a trendline to your data, Graph automatically calculates its R-squared value. If you want, you can display this value on your chart.

What does the slope of a trendline mean?
The slope of a line is the change in y produced by a 1 unit increase in x. For our example, the trend line would predict that if someone was 1-year older (x increases by 1), then they would be about 5.76 cm taller (y increases by 5.76).
