What is a dot plot and a stem and leaf plot?

Answer 1

A dot plot is a simple graphical representation that displays individual data points along a number line, using dots to signify the frequency of each value. It is useful for visualizing small datasets and identifying patterns such as clusters or gaps. A stem-and-leaf plot, on the other hand, organizes data points into "stems" (the leading digits) and "leaves" (the trailing digits), effectively preserving the original data while providing a way to visualize its distribution. Both plots are helpful for exploratory data analysis, but they serve different purposes and are suited for different types of data.
