Graphs are the summary of data that you have collected throughout your research on the ground. They represent the hard facts and convey them in a popularly understandable format. The students of statistics are meant to study graphs and produce their own. But they look for statistics assignment help when they can’t decide on how to represent their data. Here, we try to explain four types of graphs that are easy to understand and draw in your statistics assignment.

1. Line Graphs

They are used to represent data, which indicates progression. These graphs show the growth or decline of a certain entity over a period of time or with a second variable. They can include multiple data sets in a single graph and create a comparison. For example, a line graph can show the progression of Covid-19 in different countries in a single graph.
 
2. Pie Chart

They are used to represent percentages of a data point with regards to various subgroups. They are generally used when data is collected based on predefined sets. Its main advantage is that one can visualize the difference using slices that have different sizes. The most important section can also be highlighted to indicate its importance in your assignment question.
 
3. Area Graphs

These charts are used when the product of both axes is also a relevant data point. When you compare the number of units sold for different items over 5 years, the area under the curve represents total items sold and presents an overall visual comparison. They play an important role in evaluating progression with an emphasis on the volume. Businesses are in love with this type.

4. Bar Graphs

Laying different entities side by side is the best way to compare them as we did in school to ensure that the tallest one becomes a pivot in a basketball game. Here, data can be represented in sections where each one compares the length of various bars. For example, it can be the number of active Covid-19 patients in 4-5 different countries for the last six months. Then we can draw our conclusion on the policies implemented to reduce the numbers.
