Can we do curve fitting in Excel?
When we have a set of data and we want to determine the relationship between the variables through regression analysis, we can create a curve that best fits our data points. Fortunately, Excel allows us to fit a curve and come up with an equation that represents the best fit curve.

This article has been viewed 23,497 times. This wikiHow teaches you how to create a line of best fit in your Microsoft Excel chart. A line of best fit, also known as a best fit line or trendline, is a straight line used to indicate a trending pattern on a scatter chart.
Can best fit line be a curve?
Curve of Best Fit: a curve the best approximates the trend on a scatter plot. If the data appears to be quadratic, we perform a quadratic regression to get the equation for the curve of best fit. If it appears to be cubic, then we perform a cubic regression.
What is a curve best fit?
Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints.
When should you draw a curve of best fit?
A line of best fit can only be drawn if there is strong positive or negative correlation. The line of best fit does not have to go through the origin.
Can you have a curved line of best fit?
About Lines of Best Fit A line of best fit may be a straight line or a curve depending on how the points are arranged on the Scatter Graph.
Should a line of best fit be straight or curved?
In mathematics, a line (and thus a line of best fit) is, by definition, straight.
What is a best fit curve on a graph?
With quadratic and cubic data, we draw a curve of best fit. Curve of Best Fit: a curve the best approximates the trend on a scatter plot. If the data appears to be quadratic, we perform a quadratic regression to get the equation for the curve of best fit. If it appears to be cubic, then we perform a cubic regression.
