Stem-and-Leaf Plots
Stem-and-leaf plots are a graphical method used to represent data, particularly in the field of statistics. They provide a way to organize and display a set of numerical values in a clear and concise manner. Stem-and-leaf plots are particularly useful for visualizing the distribution of data and identifying any patterns or trends that may exist within the data set. In this essay, we will explore the principles behind stem-and-leaf plots, discuss how they are constructed, and examine their utility in data analysis and interpretation.
