This is a scatter diagram, showing four columns of points, slightly jittered. The horizontal scale shows the treatments and periods. The vertical scale shows Accuracy score, marked in equal intervals 40, 60, 80, 100, and 120. The columns of points are for Treatment A in Period 1, Treatment A in Period 2, Treatment B in Period 1, and Treatment B in Period 2. The four columns of points are very similar, with most points being at the top of the the column between 100 and 110 and a few points between 80 and 100. The thid column has an isolated point at about 50. For each treatment, the Period 2 points appear to be slightly higher than the Period 1 points.
