Graph fit : quadratic

Quadratic analysis and data interpolation

Paste your standard and sample data in the boxes below. For standards a single X value and one more comma-seperated Y-replicates. For sample data paste individual comma-seperated Y values for graphing and interpolation on the best-fit line.

If curve fitting is poor, trim standards outside the area of interest or select a different graph fitting style. To trim the standard curve remove the lowest or highest value and replot.

Note - we do not receive or store your data. Since graphing and analysis runs client-side only, no data is sent over the internet therefore this page runs offline or online.
