Document Summary

Stat 1000 lecture 3 examining distributions (continued) Stem and leaf plot: there are two problems that we may encounter when making a stem and leaf plot, too few stems. In this case we will split the stem. The rst will correspond to the leaves 0-4 and the second to the leaves 5: too many stems. In this case we will trim the data. Example: 101, 141, 165, 236, 247, 247, 249, 253, 254, 254, 359, 359, 389, ), omit the last digit from each entry and then make our stem and leaf plot. Data: 10, 14, 16, 23, 24, 24, 24, 25, 25, 35, 35, 38, 46, 46, 48, 56, 57, 67, The new stem and leaf plot is. Stem plots also display the shape of the data. Back-to-back stem plot simultaneously display the distributions of two related groups. Example: consider the following height data (in inches) for a group of males and females.
