## Dot Plot

## Dot Plot End code data

A dot plot is used to encode data in a dot or small circle. The dot plot is shown on a number line that displays the distribution of numerical variables where a value is defined by each dot.

A dot plot is used to represent any data in the form of dots or small circles. It is similar to a simplified histogram or a bar graph as the height of the bar formed with dots represents the numerical value of each variable. Dot plots are used to represent small amounts of data. For example, a dot plot can be used to collect the vaccination report

Now let's see the number of newborn babies who got a vaccine in each colony. Colony A has a total of 7 dots, which means that seven babies have been vaccinated. Similarly, colony B has three babies, colony C has five babies, and colony D has one baby who has been vaccinated. There are two types of dot plot: Wilkinson dot plot and Cleveland dot plot.

- Wilkinson Dot Plot
- Cleveland Dot Plot
- The dot plot shows the distribution of numerical variables where a value is represented by each dot on a number line or on graph.
- The distribution of continuous data points, such as a histogram, is shown in the Wilkinson dot diagram that displays individual data points rather than bins.
- The Cleveland dot plot shows graphical data elements and displays a continuous variable versus a categorical variable.

The Wilkinson dot plot represents the distribution of continuous data in the form of individual dots for each value. For example, if 10 students like math it is represented by 10 dots on a dot plot. In the above example of the number of kids vaccinated, the first graph showing 7 dots for colony A, 3 dots for colony B, etc is an example of a Wilkinson dot plot.

#### Dot plot is represented

The Cleveland dot plot is a good alternative to a simple bar map if you have more than a few elements. It doesn't take much to look cluttered on a bar map. Many more values can be used in a dot plot in the same amount of space, and it's also simpler to read. This type of plot is similar to a bar chart but uses a location instead of the length of the bar formed by multiple dots. Just like how the height of the bar chart represents the number of items, the position of the dot on the number line or on the graph represents the number of items for that category. In the above example of vaccinated children in 4 colonies, the second graph showing only one dot for each colony is an example of a Cleveland dot plot.
