Sort measurements into intervals and count how many fall in each. The resulting histogram shows where observations are concentrated.
Narrower bins reveal finer detail but also make random variation more visible. The height example develops from a few broad bins toward a smoother overall shape.
A smooth probability-density model estimates interval probabilities through area under its curve. Fitting a bell curve requires a suitable model; distributions need not all be bell-shaped.

Changing the bins
Narrower bins reveal finer detail but also make random variation more visible. The height example develops from a few broad bins toward a smoother overall shape.
A curve is a model
A smooth probability-density model estimates interval probabilities through area under its curve. Fitting a bell curve requires a suitable model; distributions need not all be bell-shaped.

Find a method↗
By grouping raw measurements into defined intervals (bins) and tallying the number of observations falling into each bin, a histogram is constructed. The height or area of each bar represents the frequency or count for that interval, visually revealing the regions where data points cluster most densely.
Conditions: The data consists of numerical measurements.; Measurements are sorted into predefined intervals (bins).; The count of observations in each bin is recorded.
