• Scatter diagram is a mathematical diagram.
• It is used to represent the relationship between two variables for a set of data.
• Cartesian coordinates are used for this kind of plot.
• The two variables are taken along the two axes, x and y respectively
• If there is a good relationship between the variables, the points fall in a straight line, tightly hugged with each other.
• Positive 'r' values indicate a positive correlation.
• That is as one variable increases the other variable also increases in value
• Negative 'r' value means negative correlation.
• As one variable increases the other decreases.
