In order to get an accurate idea about the shape of a distribution, relatively large samples of data are needed. This will help to capture the variability of the data and provide a more representative picture of the distribution. Computer programs may be helpful in analyzing the data and creating visual displays, but they are not necessary for understanding the shape of the distribution. Three-dimensional plots are not usually necessary and may even be misleading in some cases. Stem-and-leaf displays can be useful for examining the distribution of a small dataset, but they are not the only accurate method of presentation.
