Files with an extension of .txt are "text" files; the columns of data are separated by spaces.
Files with an extension of .csv are "comma separated value" files; the columns of data are separated by commas. These files often have an initial "header" line containing a label for each column. Each label is generally delimited by quotation marks.
ANSCOMBE contains four sets of 11 pairs of (x,y) data. Sets (x1,y1), (x2,y2), (x3,y3) and (x4,y4) all have the same average x, average y, the same regression line: y = 3 + 0.5 * x, the same variance, the same correlation coefficient, and the same value of r^2. And yet these datasets, when plotted, are obviously quite different.

Our interest is to make a scatter plot of certain pairs of real attributes.
