Dot Plot
Statistics - Dot Plot
A dot chart or dot plot is a statistical chart consisting of data points plotted on a fairly simple scale, typically using filled in circles.
Example
Problem Statement:
A study of "To what extent does it take you to have breakfast?" has these outcomes:
| Minutes | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| People | 6 | 2 | 3 | 5 | 2 | 5 | 0 | 0 | 2 | 3 | 7 | 4 | 1 |
Draw the Dot Plot for Minutes to Eat Breakfast!
Solution:
6 inspaniduals take 0 minutes to have breakfast (they most pkely had no breakfast!), 2 inspaniduals say they just burn through 1 moment eating, and so on. And here is the dot plot:
