Dot plot

A strip (jitter) plot draws one dot per observation along a single numeric axis, with slight vertical jitter so overlapping values stay visible.

What is Dot plot?

Dot plots are the right choice for tiny samples where a box plot hides too much. Each observation is one mark, so the audience sees the actual data rather than a summary.

With grouping, each group gets its own row; horizontal jitter (a small random offset) prevents overlapping dots from stacking on top of each other.

When should I use Dot plot?

Small samples (n < 30 per group) where the box plot is misleading.
Reporting raw data alongside a test result.
Communicating individual variability.

What data does it need?

One numeric column + optional grouping.

What does it report?

Strip/jitter plot.

How do I interpret the result?

Visual gaps and clusters that a box plot would smooth over are the main value — but with n > ~50 per group, switch to violin or box to avoid an unreadable mess.
