Read a bar chart as a picture of how often each value turns up.
Read a frequency or probability distribution, spot the distortion from unequal grouping intervals, and tell a PMF from a PDF.
Tally to bars (the step you are on)
Toss 10 coins again and again; each result drops a block on its heads-count column (cf. p.28).
Each toss of 10 coins drops a block on its number of heads: 0 tosses so far, and 0 of 0 coins came up heads.
