line of best fit scatter plot
When we have two separate data sets we can see if they have a relationship by plotting their points on in this manner. When we plot these points on an XY graph, we can see if a pattern forms. If a pattern forms, a relationship exists. We can examine this relationship using a Line of Best Fit Trend line. To create a Line of Best Fit we draw a line so that we are as close as possible to all the points. The Line of Best fit has two purposes in that it can help us understand the relationship between the two data sets, but it also allows us to right equation of the line.
Write an equation for the line of best fit. Oren plants a new vegetable garden each year for 14 years. Lesson Slope-Intercept form of a line. These guides can be used individually or in groups. Plot the results Figure 2: Plot results on diagram Plot all of the paired measurements onto the scatter diagram. The table shows the percent of people ages 18—24 who reported they voted in the presidential elections.

A scatter plot also called a scatterplot , scatter graph , scatter chart , scattergram , or scatter diagram  is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. The data are displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis. A scatter plot can be used either when one continuous variable that is under the control of the experimenter and the other depends on it or when both continuous variables are independent. The measured or dependent variable is customarily plotted along the vertical axis. If no dependent variable exists, either type of variable can be plotted on either axis and a scatter plot will illustrate only the degree of correlation not causation between two variables. A scatter plot can suggest various kinds of correlations between variables with a certain confidence interval. For example, weight and height, weight would be on y axis and height would be on the x axis.
