DistributionSample
Histogram
Counts how many observations fall into each range of values, revealing the shape of a distribution.
The shape of checkout times for one channel.
Sample data
Use it when
- Seeing whether values are skewed, spread or clustered
- Checking for outliers before summarising with an average
Avoid it when
- There are only a handful of observations: plot them individually
Display modes
