Estimate Value between Two Known Points
Estimate value between two coordinate pairs wey you already know.
Your numbers
y value wey interpolation give
Values outside the two input x coordinates na linear extrapolations, no be measured observations.
Compare scenarios
You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
y=y₁+(x−x₁)(y₂−y₁)/(x₂−x₁)
Estimate value between two coordinate pairs wey you already know.
Example wey show the calculation
- x for first point
- 0
- y for first point
- 10
- x for second point
- 100
- y for second point
- 30
- x value wey you want estimate for
- 50
- y value wey interpolation give
- 20
Where e fit work and limits
Values outside the two input x coordinates na linear extrapolations, no be measured observations.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
