Histograms

A histogram is a visual way to show how often different ranges of data occur. Imagine you want to understand the distribution of ages in a group. You group ages into ranges (like 20-29, 30-39) and count how many people fall into each range. These counts are represented as bars; taller bars mean more data points in that range. Histograms help you see patterns, such as whether data is evenly spread out, skewed, or concentrated in certain areas, making it easier to understand large sets of data at a glance.
