Answer :
A scatter diagram is a preliminary or initial step in exploring a relationship between two variables.
A scatter diagram is a graphical tool used to investigate the relationship between two variables. The first step in exploring a relationship between two variables is to create a scatter diagram.
This diagram shows the relationship between two variables as a set of ordered pairs of data points, where one variable is plotted on the horizontal axis and the other variable is plotted on the vertical axis.
The pattern or trend in the plotted points on the scatter diagram can provide useful information about the relationship between the variables. For example, if the points form a roughly linear pattern, it suggests a positive or negative correlation between the variables, while a scatterplot with no clear pattern suggests no correlation.
Therefore, creating a scatter diagram is an essential first step in exploring a relationship between two variables.
