What Is a Dot Plot?
A dot plot, also commonly known as a strip plot or dot chart, helps in data visualization. It is used to describe any data in a dot or small circle on a diagram with an x- and y-axis. Dot plots are not used to represent large numbers of data. So we can say that it is very useful to define a small quantity of data.
In others words “a dot plot is a graphical representation of data applying dots.”
How to Make a Dot Plot?
While creating a dot chart, data points are stacked in a column over a category. The height of the column indicates the number of observations in a given category. The categories of the dot diagram given here are the numbers from 0 to 6, where 0, and 1 occur four times, 2 occurs five times, 3 and 4 occur six times, 5 occurs 2 times, and 6 occurs 4 times.
