Scatter plots can also be combined in multiple plots per page to help understand higher-level structure in data sets with more than two variables. The scatterplot matrix generates all pairwise scatter plots on a single page. The conditioning plot, also called a co-plot or subset plot, generates scatter plots of Y versus X dependent on the value ...
Sketch a scatter plot showing the data points 6 b. Just looking at the scatter plot, estimate the value of the Pearson correlation. Positive, medium magnitude (around .3) c. Compute the Pearson correlation. SP = ΣXY – (ΣX ΣY) / N = 50 – (15 * 15) / 5 = 5 r = SP / √(SS X X SS Y) = 5 / √(18 X 18) = 5 / 18 = .278 4 1 1 3 1 4 3 1 36 4 4 ...
