In part 6, we make up an x-axis for our plot, which is the average of a given bin's boundaries. The actual plot will appear below this text-box.
What do you see? Does each number in the data set appear equally often any other? (No.) Is one data point dominant over the rest (No.) You get a bell shaped in the distribution of numbers! (This is also called a "normal" of "Gaussian" distribution.)
Do you see how stopping your analysis at the max, min, and average is a bit premature?
