Final answer:
A stem-and-leaf plot is a way to plot data and look at the distribution. It involves dividing the data into stems and leaves, with stems being the leading digits and leaves being the final significant digits. The plot helps identify the shape and pattern of the data.
Step-by-step explanation:
A stem-and-leaf plot is a way to plot data and look at the distribution. In a stem-and-leaf plot, all data values within a class are visible. To create the plot, divide each observation of data into a stem and a leaf. The stem consists of the leading digit(s), while the leaf consists of a final significant digit.
For example, 23 has stem two and leaf three. The number 432 has stem 43 and leaf two. The stem values are written in a vertical line from smallest to largest, with a vertical line to the right of the stems. The leaves are then written in increasing order next to their corresponding stem. The plot helps identify the shape and pattern of the data.
