Consider the graph below. This shows the results of an experiment training condition as the independent variable and employee IQ as the covariate.

What does the graph indicate?
A) Although the independent variable has had an effect on the dependent variable, the covariate is the more likely explanation of effect.
B) The training condition has altered IQ.
C) IQ has altered learning condition.
D) Not enough information.

The graph shows a significant difference in the dependent variable (learning condition) based on the independent variable (training condition), but there is also a clear relationship between employee IQ and learning condition. Therefore, the effect of the independent variable on the dependent variable may be partially due to the influence of the covariate, employee IQ.
