We want to describe an example situation in which a dot plot will be an appropriate data display. First let's recall that we use a dot plot to show the number of times each numerical value occurs in a data set. Imagine that we roll a six-sided die.
When we roll a six-sided die we have 6 possible outcomes that are in form of numbers. Therefore, we can use a dot plot to show how many times each outcome occurred after a particular number of trials. The dot plot for 30 rolls could look like the following.
Notice that this is only an example solution as a dot plot can be an appropriate data display for many other situations.
