Marvelous Correlation Line Graph
The Prism correlation matrix displays all the pairwise correlations for this set of variables.
Correlation line graph. Correlation measures the strength of a linear relationship which means the pattern looks roughly like a line. Line Charts In the line chart you can record the continuous periodic data conveniently. In diagram b the x- and y-variables have a negative relationship.
Answering queries about the data. For example demand and profit are positively correlated the more the demand for the product the more profit hence positive. For a correlation coefficient of zero the points have no direction the shape is almost round and a line does not fit to the points on the graph.
The graph to the right is an example of a non-linear relationship. They are positively correlated. The blue boxes represent variables that have a positive relationship.
Is the relationship weak moderate or strong Is the relationship linear. It does not fit a line. When two variables increase together and decrease together.

View the sources of every statistic in the book. We interpret line graphs by studying and analysing data from line graphs. The red boxes represent variables that have a negative relationship.
