Histogram

A Histogram is a classic and essential tool for visualizing the distribution of a single continuous variable. It groups data into a series of bins or intervals and displays the frequency of observations in each bin as a bar. This provides a clear, at-a-glance understanding of the data's underlying distribution, including its central tendency, spread, skewness, and modality (the number of peaks). Histograms are fundamental to exploratory data analysis, helping you to understand your data's characteristics before applying more complex statistical methods. They are perfect for analyzing exam scores, heights, weights, or any numerical dataset.
