A box-and-whiskers graph, also known as a box plot, is especially useful for summarizing statistics from a set of data with emphasis on its distribution, central tendency, and variability. It provides a visual representation that displays the minimum, first quartile, median, third quartile, and maximum of the dataset.

When dealing with multiple pH readings, a box-and-whiskers graph effectively conveys important statistical information, such as the range of values, any outliers, and the spread of the data. This is particularly beneficial in scientific contexts, like environmental studies or laboratory experiments, where understanding the distribution of measurements is crucial for analyzing trends or patterns.

In contrast, other scenarios, such as comparing individual household expenses, seeing sales trends over two years, or comparing sales of different types of books, generally require different forms of visualization that detail specific comparisons or changes over time, rather than summarizing distributions. Thus, the box-and-whiskers graph stands out for its ability to succinctly summarize and display multiple readings in a clear and informative manner.
