There are some key assumptions that should be met before Pearson’s correlation can be used to give valid results: Figure 1: Scatter plots showing examples of linear and non-linear relationships.

Guess the Correlation is a very simple game indeed: Look at a scatter plot, guess the correlation coefficient, win or lose. Are you mathematically minded enough to take on the challenge?

In this task, the canonical correlation analysis is performed, labels are specified to identify each set of canonical variables, and a plot of the canonical variables is requested. You can optionally ...

A plot of the correlation function of a given DNA sequence has certain characteristic features common to almost all organisms. One common feature is that the correlation values at distances that ...

Your job is to eyeball the plots and estimate a number called R, which measures how correlated the two things are. In the game, R can range from 0 (no correlation at all) to 1 (a perfect positive ...

Despite the chant that correlation is not causation, some researchers believe the design of scatter plots nudges us to the wrong conclusions. Can a change in their design lessen that risk? Analyzing ...

When the CROSSCORR= option is used, PROC ARIMA prints a plot of the cross-correlation function for each variable in the CROSSCORR= list. This plot is similar in format to the other correlation plots, ...
