You could use discrete data on one scatter plot axis and continuous data on the other. Continuous data lets you measure things deeply on an infinite set and is generally make use in scatter analysis. ( See notes on the different data types here.)ĭiscrete data is best at pass/ fail measurements. Scatter analysis generally makes use of continuous data. What Kind of Data Should You Use for Scatter Analysis? Defining if there is a relationship between two variables.Dependent variables have multiple values for each figure associated with the independent variable.Pairs of numerical figures are present.Specific instances of when to utilize scatter diagrams: Scatter Diagrams show the “cause-and-effect” relationship between two kinds of data and provide useful information about a production process. We are talking about this kind of analysis when we are trying to get at the root cause of an issue. The analysis comes in when trying to discern what kind of pattern (if any) is present and what that pattern means. Scatter plots are a way of visualizing the relationship by plotting the data points, you get a scattering of points on a graph. Why You Would Use Scatter Analysis and Scatter PlotsĪ Scatter Analysis is used when you need to compare two data sets against each other to see if there is a relationship. A Scatter Diagram shows a relationship between two variables and provides a visual correlation coefficient.
