A bar graph maker can be a great way to easily and quickly create graphs for data analysis. However, to make the most of your bar graph maker, it is important to first gather your data correctly. Here are some tips on how to do just that:
1. Make Sure Your Data is Organized and Easy to Read in Your Free Bar Graph Maker
When you are gathering data for a bar graph, it is important to make sure that it is easy to read. This means organizing your data into rows and columns and ensuring that all of the values are clearly labeled. It can also be helpful to use color coding or different symbols to distinguish between different types of data.
2. Use a Consistent Scale for All of Your Data
When you are creating your bar graph, all of the different pieces of data should be measured using the same units. It is also helpful to use a consistent scale throughout your bar graph so that it is easy to compare values across bars.
To do this, try picking one value for your smallest unit and then dividing or multiplying it by 10 for each successive piece of data (see example below). This way, each bar on your chart will represent 100 units (10 * 10 = 100) rather than having some bars with lengths representing 50 units while others have lengths representing 500 units.
Once you have set up your scale, stick to it, as switching back and forth between scales can make interpreting your results more difficult.
3. Be Careful With the Outliers of a Bar Graph Maker Online
Outliers are data points that fall very far from the rest of the data and can have a large impact on your graph if they are included or excluded from your analysis. For example, the following graph shows two sets of data gathered from measuring different plants in a greenhouse:
In this example, including or not including the outlier dramatically changes how we view our results. If we include it, then it appears as though plant A is growing faster than plant B. However, if we exclude it, then it looks like there is no significant difference between the two plants.
This highlights why it is important to look at only a few key data points when using a bar graph maker rather than trying to gather too much data. If you do decide to include an outlier in your graph, be sure to label it clearly so that readers of your graph know what they are looking at and why it is included.
4. Check for Accuracy Before Making the Final Version of Your Easy Bar Graph Maker
Once you have gathered all of your data, take a look at it before making the final version of your bar graph. Make sure that each piece of data is clearly labeled and that there are no typos or missing data points.
This last check can save you from having to go back and make revisions after you have already created the complete version of your bar graph!
5. Try Using Different Colors or Symbols When Creating an Online Bar Graph Maker
When creating multiple bar graphs to represent data that uses different scales or measures different things, consider using different colors, symbols, or a diagram on your bars to help distinguish between the results.
This makes it easy for readers to quickly look at each graph and determine what type of data each one represents. For example, if you were looking at the growth rates of several different types of plants, you could use a green circle to represent plant A in one graph and a red square to represent plant B in another graph.
In this way, even without reading any labels or captions accompanying the bars, viewers can immediately see that the first bar represents plant A’s height over time while the second bar represents plant B’s height over time.
6. Keep in Mind That a Simple Bar Graph Maker Can Be Used to Compare Values
When you are creating your bar graph, keep in mind that you can use it to compare values as well as just to display data. For example, the following graph shows the average daily temperatures for two different months:
In this example, the bar graph is not just displaying the average temperature for each month but it is also comparing the average temperature for January to the average temperature for February. This can be done by making the length of each bar proportional to the value that it represents (so that the taller bars represent bigger values) and then using a different color or symbol for each set of data.
Venngage offers a wide selection of bar graph templates that can be used in showing data for statistics. Be sure to check it out!
Conclusion
A bar graph is a visual representation of data. It can be used to show the magnitude or size of changes over time, differences between groups, and the relationship among different variables. Data can be collected by hand or with computer software. There are many ways to create your bar graphs using online tools that are available for free on the internet.
