- Create a graph that displays key information from quantitative data
- Explain the differences between different graphs that display the same quantitative data
Dotplots
dotplot
Dotplots display how many individual observations there are of each value observed, so each observation in the data set appears as its own dot on the graph.
A large number of observations could overwhelm the display so dotplots work well when the data set is small.
Steps to create a dotplot:
STEP 1: Select “Single Group.”
STEP 2: Select the Data Set “Oscars: Age.”
STEP 3: Under “Choose Type of Plot”, select “Dotplot.”
STEP 4: Choose a “Dotsize” or “1”, and a “Binwidth” of “1.”
