| Jun 19 at 2:54 | comment | added | nickalh | For some strange reason both answers deal with the same incorrect assumption, so this seemed to be the most appropriate place to put the comment. As a general rule, unless I have evidence to the contrary I assume the professor makes reasonable interpretations. | |

| Jun 10 at 21:58 | comment | added | whuber♦ | That is correct -- but your comment seems to apply to one of the answers, not your question. Using zeros in the leaves is inferior because it loses the opportunity to present the data in greater detail at no additional cost in the space used or complexity of the presentation. In the example, because the interval between the stems is 2, the leaves would at a minimum indicate whether each number is odd or even. | |
| Jun 10 at 20:50 | comment | added | nickalh | I finally have some more time to read the answers more thoroughly. At the level of introductory first semester stats, stem and leaf plots, often use the tens digit, and if relevant, the 100's digit, on the left column and use the ones digit on the right column. Indeed, having entirely 0's on one side of a stem and leaf plot seems a bit of a waste. | |

| Jun 7 at 1:19 | comment | added | nickalh | Feel free to add any appropriate tags. I didn't see any others for charts, displays, visual representations, introductory stats, etc. Also, I'll be mostly unavailable until Monday June 10, but will be free respond to comments and answers then. | |
