Frequently Asked Question

Questions asked by users might not always be phrased in the clearest way.

What is the relationship between the number of points and the percentage of linearity (r2) in the calibration curve?

Accepted Answer

The number of data points in a calibration curve influences the R-squared (R²) value, which represents the linearity of the curve. More data points generally lead to a higher R² value indicating a better fit and stronger linear relationship between the analyte concentration and the measured signal. However, the number of data points is not the sole factor; the quality and distribution of the data points are also crucial. A calibration curve with a large number of points clustered in a narrow range may still have a lower R² than a curve with fewer points spread across a wider range, if the data is more scattered in the latter case.
