Histograms
A histogram is a graphical representation of the distribution of a dataset. It consists of rectangular bars where each bar’s height represents the frequency, or the number of observations, within each bin. Bins are defined intervals into which the data is segmented, and the bars show how many data points fall into each interval.
Histograms are invaluable for visualizing a dataset's distribution and for identifying patterns, trends, and potential outliers. They also provide insights into the data's spread, skewness, and overall variability.
