Create Pareto Chart In Excel
What is Pareto Chart?
Pareto principle was introduced by Italian Economist Vilfredo Pareto. He stated that 80% of the effects are caused by 20% of the causes. So if we closely monitor and solve 20% of the causes. It will significantly improves the affected area and you will see good results.
For Example: 80% of the revenue gets generated by 20% of the clients
While doing research Mr. Pareto found that 20% of land in Italy was occupied by 80% of the population. He carried out this survey to other areas and got same results
This rule is also well known as 80/20 rule across the globe and is mostly being used to find the causes which is impacting business or producing defective products/services
Hence Pareto chart is a graphical representation of Pareto Principle
When to use Pareto Chart in your study?
Pareto Chart studies the frequency distribution and advise you the most impacted/affected areas. So you should use Pareto Chart when:
- While analyzing defects/problems data, you find too many causes and want to focus most significant areas
- While analyzing broad categories and you want to focus only on few causes which may improve the metric significantlly
- When you have data frequency distribution and you want to analyze and focus on main contributing causes
- In your project managements templates or dashboard making to summarize the data
- Analyzing the Surveys and finding pain areas
How to create Pareto Chart in Excel?
Here are few steps to collect data before you start preparing your Pareto Chart in Excel:
- Decided which data you want to study
- It is always good, if you can group or categorize the data labels
- Collect data frequency/numbers for each above categorized data labels
- Sort your data in excel from Largest to Smallest as shown below:
Here I collated the Complaints data from one of the Courier Company survey and will create Pareto Chart for them. Lets follow the steps now:
-
Calculate cumulative frequency for each data point.
In order to do this, add a column for Cumulative Frequency as shown below and link the first cell in this column with the first data point as shown (The Largest Number):
- Second Row should be total of Last CF + Respective Data Point. You need to copy the same formula or drag the same till last data point. Please look at below image:
- Last Row in Column C as per below image shows the total of Column B. Refer to below image:
-
Now Calculate CF% in another Column. Here it is column D which is dividing the
= Cumulative Frequency / Total of Data Points
- Last Point in Column D will show 100% as shown below:
Steps to Create Pareto Chart:
-
Click on any blank cell in Excel where you want to create the chart
Select "Insert" option from menu bar and select 2-D Clustered Column Chart
-
This will insert a blank Chart on your screen where we will be creating Pareto Chart.
Right Click on blank chart and "Select Data":
-
Now you will see below window on your screen. Click "Add"
-
Here we will be adding "y axis" entries with this step as shown in below image:
Series Type: "Complaint"
Series Values: This is data range which is currently "B2:B10" in displayed data and as this data is on Sheet1. So this will show like "=Sheet1!$B$2:$B$10" (Absolute Range)
Once you complete above steps. Click "OK" and follow next step
- Now you will see the "Select Data" window again. So here you need to click "Add" again:
-
Here we will be adding second "y axis" which is CF% with the same steps followed above. So once you click Add, enter the values as mentioned below:
Series Type: "CF%"
Series Values: This is CF% which was calculated in Column D which is currently "D2:D10" in displayed data and as this data is on Sheet1. So this will show like "=Sheet1!$B$2:$B$10" (Absolute Range)
Once you complete above steps. Click "OK" and follow next step
-
Now we will be adding "x axis" which will denotes the complaints type at bottom. So that user can interpret the results for each complaint. So click on "Edit"
-
Below window will appear and then you need to select the "x-axis" range as below:
Axis Label Range: Complaint Types which are currently in range "A2:A10" on Sheet1. So this will show like "=Sheet1!$A$2:$A$10" (Absolute Range)
Once you complete above steps. Click "OK"
- Now "Select Data" chart window will look like below and then click "Ok"
- Right Click on the chart and select "Change Chart Type" as shown below:
- Below window will appear and then you need to follow steps as shown in the image in sequence:
- Here is your pareto chart ready:
So here your Pareto chart is ready. This will help you to showcase the major pain areas or impacted areas in visual display
