You work out the standard deviation (do you need the formula?) and draw a bar above and below (+-SD) the mean value (apex of bar chart).

Just draw small lines, say the SD is 0.1 then you need to do a small line that goes 0.1 above and 0.1 below the plotted point on the graph.

yeah, but each box is equivalent 1, so 0.1 is very small when I'd draw the range bars?

Use the smaller boxes which represent 0.1

Accurate enough, but obviously you're not going to be able to draw 0.09 etc to an accurate degree.
