About the Histogram
A histogram groups continuous data into bins (intervals) and displays the count or frequency of values in each bin as bars. Unlike a bar chart, histogram bars have no gaps because the x-axis represents a continuous range.
Histograms reveal the shape of a distribution: is it symmetric, skewed, bimodal, or uniform? They are essential for understanding data before analysis.
