Master small datasets with dot plots
Dot plots are ideal for visualizing distributions, particularly when dealing with smaller datasets. They offer a clear and intuitive way to show the frequency of individual data points. This makes them useful for quickly identifying clusters, outliers, and the overall shape of the data. Compared to histograms, dot plots maintain the identity of each data point. This level of detail is beneficial when precise values are crucial and the sample size is not overwhelmingly large. They are easy to understand and interpret, making them a good choice for presentations and reports aimed at a broad audience.
