What are Dot Plots

What are dot plots and why should you use it?


So what actually are dot plots?


A dot plot is a graphical tool that can be used to display data in a variety of ways. A dot plot shows data distribution by plotting dots for each observation. Dot plots can be used for both categorical and quantitative data. Additionally, dot plots can be used to compare multiple distributions or to look for relationships between variables.

When looking at a dot plot, there are a few things to remember. First, the dots should be placed close together to form a line. Second, the order of the dots should be from left to right in ascending order. Third, make sure that each dot represents only one data point. Finally, you may want to add a title and axis labels to your dot plot so that others can easily interpret your data.


How to Create a Dot Plot


Creating a dot plot is a relatively simple process. First, you will need to collect your data. Next, decide how you want to group your data. For categorical data, you can group by levels of the variable (e.g., by country or by type of product). For quantitative data, you will need to decide on an appropriate unit of measurement (e.g., by years or by months). Once you have decided on your grouping, create a list of all of the values in your dataset.

Next, create your dot plot using graph paper or a spreadsheet program like Microsoft Excel. To do this, simply draw a line for each value in your list and then place a dot above the line at the appropriate location. If you are using Excel, you can use the “scatter” or “line” chart functions to create your dot plot. Be sure to add titles and axis labels as needed!

When To Use Dot Plots


Dot plots are versatile tools that can be used in many different situations. One everyday use for dot plots is to compare two or more distributions side-by-side. This is especially helpful when you want to compare distributions with different shapes (e.g., if one distribution is skewed while another is symmetric). Another use for dot plots is to look for relationships between variables; for example, you could use a dot plot to examine how monthly sales vary based on the time of year.




Dot plots are powerful graphical tools that can be used in many different ways. Whether you’re looking to compare multiple distributions or examine relationships between variables, dot plots can help you see your data in new ways. Creating a dot plot is easy–simply draw a line for each value in your dataset and then place dots at the appropriate locations–and with just a little practice, you’ll be creating stunning visualizations in no time!
