Detailed explanation-1: -The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve.
Detailed explanation-2: -The scatter diagram helps to confirm if the two variables are co-related and also helps in determining the strength of the relationship between the two variables studied. To illustrate how to use the scatter diagram, let’s consider the following example.
Detailed explanation-3: -Scatter Plots Things to look for: If the points cluster in a band running from lower left to upper right, there is a positive correlation (if x increases, y increases). If the points cluster in a band from upper left to lower right, there is a negative correlation (if x increases, y decreases).
Detailed explanation-4: -Scatter plots are the graphs that present the relationship between two variables in a data-set.
