A polynomial trendline is a curved line that is used when data fluctuates. It is useful, for example, for analyzing gains and losses over a large data set. The order of the polynomial can be determined by the number of fluctuations in the data or by how many bends (hills and valleys) appear in the curve. An Order 2 polynomial trendline generally has only one hill or valley. Order 3 generally has one or two hills or valleys. Order 4 generally has up to three.
A trend line, often referred to as a line of best fit, is a line that is used to represent the behavior of a set of data to determine if there is a certain pattern. A trend line is an analytical tool used most often in conjunction with a scatter plot (a two-dimensional graph of ordered pairs) to see if there is a relationship between two variables. Let's take a quick look at the main purposes of a trend line: 1. Determining if a set of points exhibits a positive trend, a negative trend, or no trend at all. Looking at the red trend lines in the examples illustrates various relationships with sets of data. 2.
