Polynomial regression is a type of regression analysis where the relationship between the independent variable (X) and dependent variable (Y) can be modeled as an nth degree polynomial function. In Excel, you can perform polynomial regression using the LINEST function.
Interpolation is the process of estimating values within the range of available data. It is a fundamental tool in data analysis and visualization, and it can be performed effortlessly in Excel using various techniques. Unlike extrapolation, which estimates values beyond the available data range, interpolation focuses on providing accurate estimates within the known data boundaries.
In this article, we will explore the methods and steps to interpolate in Excel effectively. We will start by discussing the different types of interpolation, and then we will provide step-by-step instructions on how to perform linear and polynomial interpolation. Finally, we will discuss the precision of interpolation and its use cases.

The profit margin formula in Excel is a simple calculation that helps you determine the percentage of profit generated from sales revenue. It’s a valuable financial metric for assessing a company’s profitability. The formula for calculating profit margin is:
In Excel, you can easily find the range of a set of numbers or values using the MIN and MAX functions. The range is defined as the difference between the highest (maximum) and lowest (minimum) values in a dataset.
Here’s how you can calculate the range in Excel:
This article will show you how to do an exponential regression in Excel. Exponential regression is a statistical method that can be used to fit an exponential function to a set of data points.
Extrapolation is the process of estimating values beyond the range of available data. In Excel, extrapolation can be done using various methods, including linear regression, exponential regression, and polynomial regression. In this article, we will discuss how to extrapolate in Excel using these methods.
In this Excel tutorial you will learn how to perform a DCF analysis in Excel.
A discounted cash flow (DCF) analysis is a financial model used to estimate the intrinsic value of an investment or project. This method takes into account the future cash flows generated by an investment, discounted to their present value using a discount rate.
