scatterplot

 [skat´er-plot]
a plot in rectangular coordinates of paired observations of two random variables, each observation plotted as one point on the graph; the scatter or clustering of points provides an indication of the strength of the relationship between the two variables.

The relevance of the covariates in the final model depended on comparing the values of AIC as well as the evaluation of the visual diagnostic scatterplots of goodness-of-fit that detects the observed versus predicted concentration based on bias, and imprecision.

Further inputs reveal that a moderate positive correlation exists between the variables (Multiple R = 0.455), a fact graphically back up by the scatterplot in Figure 4 (median age of the population is placed in the y axis, while the number of cars per 1000 inhabitants on the x axis), in which the trendline is on a rising path: as the average value of the median age increases, the trendline follows with a right shift.
The spatial organization of categories--indicated by the sign and magnitude of the Coordinate column (Table 2) and visual inspection of categories plotted across the horizontal axis of each scatterplot (Figure 1)--provides initial evidence for interpreting Dimension 1.
