Scatter plots. A scatter plot is a graph that shows the relationship between the observations for two data series in two dimensions.. Scatter plots are formed by using the data from two different series to plot coordinates along the . Amine Ouazad. Ass. Professor of Economics. Problemo. OLS is plagued by the problem of omitted variables…. It is not a testable assumption.. (remember the exercise?). An instrumental variable can circumvent the problem by providing us with an “exogenous” source of variation of the covariate.. SPSS. Karl L. Wuensch. Dept of Psychology. East Carolina University.
