What is the correct way to construct a scatterplot?
Scatter Diagram ProcedureCollect pairs of data where a relationship is suspected.Draw a graph with the independent variable on the horizontal axis and the dependent variable on the vertical axis.
Look at the pattern of points to see if a relationship is obvious.
Divide points on the graph into four quadrants.More items….

two variablesA 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.
How do you interpret a scatter diagram?
You interpret a scatterplot by looking for trends in the data as you go from left to right: If the data show an uphill pattern as you move from left to right, this indicates a positive relationship between X and Y. As the X-values increase (move right), the Y-values tend to increase (move up).
What type of association is shown by the scatterplot?
A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative.
How do you make a scatter plot with colors in R?
The different color systems available in R have been described in detail here. To change scatter plot color according to the group, you have to specify the name of the data column containing the groups using the argument groupName . Use the argument groupColors , to specify colors by hexadecimal code or by name .

How do I make a scatter plot in R?
A scatter plot can be created using the function plot(x, y). The function lm() will be used to fit linear models between y and x. A regression line will be added on the plot using the function abline(), which takes the output of lm() as an argument.
How do you change the color of a plot in R?
