  2. A trend line with a negative slope indicates a negative relationship between the two variables.

How do you interpret a trendline in Excel?

Additionally, Microsoft Excel allows displaying a trendline equation and R-squared value in a chart:

  1. Trendline equation is a formula that finds a line that best fits the data points.
  2. R-squared value measures the trendline reliability – the nearer R2 is to 1, the better the trendline fits the data.

Uptrend lines are upward sloping, and downtrend lines slope down. Uptrend lines are underneath prices, marking areas of potential support. Downtrend lines are possible resistance areas, and must be drawn above prices. It’s drawn between lows in a downtrend instead of between highs in a downtrend.

How do you determine if the trendline is a good fit?

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 is the slope of a trendline in Excel?

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.
