![]() You will often see the variable on the horizontal axis denoted an independent variable, and the variable on the vertical axis the dependent variable. In these cases, we want to know, if we were given a particular horizontal value, what a good prediction would be for the vertical value. Identification of correlational relationships are common with scatter plots. The dots in a scatter plot not only report the values of individual data points, but also patterns when the data are taken as a whole. Scatter plots’ primary uses are to observe and show relationships between two numeric variables. This tree appears fairly short for its girth, which might warrant further investigation. We can also observe an outlier point, a tree that has a much larger diameter than the others. From the plot, we can see a generally tight positive correlation between a tree’s diameter and its height. Each dot represents a single tree each point’s horizontal position indicates that tree’s diameter (in centimeters) and the vertical position indicates that tree’s height (in meters). The example scatter plot above shows the diameters and heights for a sample of fictional trees. Scatter plots are used to observe relationships between variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. It does not store any personal data.A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables.

The closer the data points come when plotted to making a straight line, the higher the correlation between the two variables, or the stronger the relationship. The relationship between two variables is called their correlation. Scatter plots show how much one variable is affected by another. Each member of the dataset gets plotted as a point whose x-y coordinates relates to its values for the two variables. What type of data does a scatter plot show?Ī scatterplot is a type of data display that shows the relationship between two numerical variables. These are: positive (values increase together), negative (one value decreases as the other increases), null (no correlation), linear, exponential and U-shaped. Various types of correlation can be interpreted through the patterns displayed on Scatterplots. Divide points on the graph into four quadrants.Look at the pattern of points to see if a relationship is obvious.Draw a graph with the independent variable on the horizontal axis and the dependent variable on the vertical axis.Collect pairs of data where a relationship is suspected. ![]() In this example, each dot shows one person’s weight versus their height. What is an example of scatter plot?Ī Scatter (XY) Plot has points that show the relationship between two sets of data.
