Best ResponseYou've already chosen the best response.1A stem and leaf plot shows the number on the left representing the place number of the right digit. I.E, in the graph above, you have column 0. You have the numbers 03, 06, 09. For column 1, you have 12, 15, 16, 19. For column 2, you have 21, 23.
