How To Construct A Standard Curve In Excel

Introduction

Creating a standard curve in Excel is a fundamental task for many scientific and analytical applications, involving the plotting of known concentrations against measured values to establish a relationship. This process is essential for quantifying unknown samples based on their response.

While Excel requires manual configuration of functions and features, which can be tedious and time-consuming, there's a better way. In this guide, we'll explain how to construct a standard curve in Excel and explore how Sourcetable's AI-powered chatbot can instantly generate standard curves and perform complex data analysis by simply telling it what you need - try it now at https://app.sourcetable.com/.

Constructing a Standard Curve in Excel

Initial Setup

To begin constructing a linear standard curve in Excel, prepare your data with two variables: the independent variable (known values) on the x-axis and the dependent variable (measured values) on the y-axis.

Creating a Scatter Plot

Insert a scatter plot by selecting your data and using the 'Insert' menu to choose 'Scatter'. This visual representation will form the basis of your standard curve.

Adding a Trendline

After plotting your data, add a trendline by right-clicking on a data point and selecting 'Add Trendline'. For a linear standard curve, choose the 'Linear' option.

Equation and R-squared Value

Ensure that the trendline's equation and R-squared (R2) value are displayed by checking the appropriate boxes in the trendline menu. The R2 value indicates the accuracy of the fit, ideally close to 1, while the equation is used for calculating unknown sample values.

Calculating Unknowns

With the equation from the trendline, apply it to calculate the values of unknown samples by inputting the independent variable values into the equation.
