Cedar Courier Delivery Times

Cedar Courier Delivery Times — Dot Plot

This dot plot keeps each observation visible instead of reducing the sample to an average. Equal values stack vertically, making the most common measurements, gaps and potential outliers easy to find. The horizontal axis uses the unit relevant to the sample, while the vertical stacking only separates repeated observations; it is not a second measured variable. This format is especially useful for a small operational sample or a classroom dataset where exact values matter. The chart should be interpreted with its collection context in mind, including how observations were selected and whether the sample is representative. For larger datasets, grouping observations into bins can improve readability.

Perguntas frequentes

Dúvidas comuns

Why are dots stacked?

Stacking separates repeated values so their frequency is visible.

What does the horizontal axis show?

It shows the measured value for each individual observation.

When should I use a histogram instead?

Use a histogram when the dataset is large enough that individual dots become crowded.
