1. ANATOMY OF A DOTPLOT
Typically used for a small data set, a Dotplot uses a dot for each time a value occurs. For example, there were two occasions where the time between eruptions was 47 minutes. For larger data sets a dot may represent more than one occurrence of a value. Dotplots display the distribution of a data set’s values across its range .
Building a Dotplot:
1) Draw the horizontal axis.
2) Label the axis (pounds, cm., %, etc.) and insert the scale being used (e.g. 0 – 85% ).
3) Place a dot above the scale line for each occurrence of a value.
4) Add a title describing the chart’s contents and any other information about the data that might be useful.
Title
Y-axis label (here Frequency) is generally not found as the stacks represents counts
THE DOTS:
One per occurrence
The labeled x-axis represents the value being collected (here minutes).
