Have you heard the saying—Data is the new oil?
It means data is valuable; it’s expensive, and when utilized well, it can make you rich. But having tons of data at your fingertips is only half the job. The real game changer is—how you interpret and visualize that data to get business and customer insights.
If you’re not using effective data visualization tools, it’s easy to miss key trends and variations.
That’s where control charts come into play!
A control chart is a tool used to analyze how a process evolves over time. It displays data in chronological order and includes three key lines: a central line representing the average, an upper control limit, and a lower control limit. These lines are established based on historical data to help identify trends and variations in the process.
Control charts are crucial for businesses to monitor data trends and make informed decisions. You can create a control chart in Microsoft Excel to get started. In this blog post, we’ll explain how to create a control chart in Excel.
How to Create a Control Chart in Excel?
Summarize this article for me pleaseHow to Create a Control Chart in Excel?
A control chart in Excel provides a visual data report, helping track process performance and spot trends over time.
Here is a step-by-step process to create a control chart in Excel.
Step 1: Prepare the data set
Before creating a control chart, you need a well-organized data set to ensure your control chart is based on reliable and clean data. This helps you identify any variations or trends accurately. Make sure the data is organized with clear labels for each variable and there’s consistent formatting for each entry.
Here is a data set containing daily sales figures from a store over 20 days. The sales figures for each day must be recorded in a separate row or column.
Step 2: Calculate the Mean
Next, we have to calculate the mean sales amount.
The mean, or average, is a measure of central tendency in statistics. It provides a benchmark figure from the data set and helps us identify variations in sales amounts. To calculate the mean in Excel:
- Select the cell where you want to display the mean
- Enter the formula: =AVERAGE(range), where range is the set of cells containing your data
- Press Enter to calculate the mean
For our example, we have typed =AVERAGE(B2:B21) in the formula bar to calculate the mean for the sales figures in cells B2 to B21.
In this case, our average sales value over 20 days is $230.75.
Step 3: Calculate the Standard Deviation
The standard deviation measures the dispersion or variation in the data set, showing how much the individual data point deviates from the mean.
To calculate the standard deviation in Excel:
- Select the cell where you want to display the standard deviation
- Enter the formula: =STDEV(range), where range is the set of cells containing your data
- Press Enter to calculate the standard deviation
In our case, we will enter =STDEV(B2:B21) to find the sample standard deviation for the sales figures.
Step 4: Establish the control limits
Once you find the mean and standard deviation, calculate the upper and lower limits to determine whether the data points are within the normal range of variation. In this case, the Upper Control Limit (UCL) and Lower Control Limit (LCL) tell the normal sales range.
If the sales value is below the lower limit, identify the causes of poor sales, such as supply chain disruptions or reduced demand in the market.
Similarly, sales value above the upper limit can indicate positive shifts in market demand or effective marketing campaigns. These limits help analyze market trends and make data-driven decisions.
- Calculate the Upper Control Limit (UCL):
- Select the cell where you want to display the UCL
- Enter the formula: =AVERAGE(range) + STDEV(range)*3, replacing range with the cells containing your data
- Press Enter to calculate the UCL
For example, to calculate the upper limit for sales data, we will use =AVERAGE(B2:B21) + STDEV(B2:B21)*3.
- Calculate the Lower Control Limit (LCL):
- Select the cell where you want to display the LCL
- Enter the formula: =AVERAGE(range) – STDEV(range)*3, substituting range with the cells containing your data
- Press Enter to calculate the LCL
For the sales data, we will add =AVERAGE(B2:B21) – STDEV(B2:B21)*3 to determine the LCL.
Step 5: Create a control chart
Once you are done calculating control limits, you can now create a control chart to visualize the data:
- Select the cells containing the sales figures
- Click on the Insert tab in the Excel toolbar
- Click on Insert Line or Area Chart, and then select the Line option to create a line chart
Step 6: Add data series to the control chart
To make the control chart more informative, add data series to represent the mean, UCL, and LCL:
- After creating the control line, right-click on the chart
- Choose Select Data from the context menu
- In the Select Data Source dialog box, navigate to the Add button. A pop-up named Edit Series will appear
- Enter details for each data series:
- Mean data series:
- Series Name: Enter the cell name you want to appear in the chart legend to identify the data series. Since we are showing the mean, we used “Sheet1!$C$1”, which refers to the label in cell C1
- Series Values: In the series values field, type the range of cells that contains the mean values. For our example, since the mean values are in cells C2:C21, we will type =Sheet1!$C$2:$C$21
- Mean data series:
- Click OK to add the series to the control chart
- Upper Control Limit (UCL) Data Series:
- Repeat the process for the UCL data series, entering the appropriate range for UCL values
- Lower Control Limit (LCL) Data Series:
- Repeat the process for the LCL data series, entering the appropriate range for LCL values
- Click OK to apply all the changes and view the completed control chart
Step 7: Customize your chart
You finally have your chart ready! Excel also offers a range of options to present your chart exactly the way you like. For instance, you can:
- Chart title: Click on the chart title to edit it. Enter a descriptive title that reflects the chart data
- Axis Titles: Add titles to the X and Y axes to clarify what each axis represents. Click on the chart, go to the Chart Elements button (the plus sign), and select Axis Titles. Then, click on each title to enter the labels
- Legend position: Adjust the legend to ensure it doesn’t obstruct important parts of the chart. Excel lets you drag the legend to various positions, including top, bottom, left, or right, so you can choose a spot that keeps your chart clear and readable
- Line styles and colors: Make your data series stand out by customizing line styles and colors. Right-click on a line in the chart, select Format Data Series, and you can change the line color, style, or width to differentiate between various series or to match your preferred color scheme
- Data labels: Show specific values on the chart by adding data labels. Click on the data series, go to the Chart Elements button, and check the Data Labels option. You can position these labels directly on the chart to provide precise information at a glance
- Gridlines and background: Adjust gridlines and the chart background to enhance clarity. You can modify grid line settings or change the background color to make your chart more visually appealing or easier to read
By following these steps, you can create a control chart in Excel that visualizes data along with the calculated mean and control limits. This will help you identify any variations or trends within the data set. Be sure to adjust the cell ranges based on where your data is located.
Summarize this article for me pleaseLimitations of Creating Control Charts in Excel
Creating control charts or graphs in Excel is useful for straightforward data analysis, but it has a few drawbacks that can affect the accuracy, efficiency, and overall effectiveness of your data analysis. Here are some limitations to keep in mind:
- Manual effort and updating: In Excel, you have to enter data manually, set up formulas, and update charts whenever you have new data. This becomes challenging if you’re working with large data sets or need to make frequent updates
- Basic statistical capabilities: Excel is great for basic calculations, but it doesn’t have advanced statistical process control. For example, if you’re looking to create more complex control charts, like CUSUM (cumulative sum) or EWMA (Exponentially Weighted Moving Average) charts, you’ll need to use a specialized tool
- Data handling limits: If you’re working with really large data sets, Excel can slow down or even crash, causing delays in data analysis
- Susceptibility to human error: Since the control chart in Excel relies on manual data entry and formula setup, there’s always a chance of making a mistake. A small typo or the wrong formula can lead to incorrect charts and potentially flawed analyses. This can be risky, especially if you’re making decisions based on the data presented in these charts
- Limited collaboration and integration: Excel isn’t built for teamwork. Sharing files back and forth is a hassle, and without real-time collaboration features, it’s easy to end up with multiple versions of the same document. Plus, Excel doesn’t integrate well with other data management systems, which can make it tricky to keep everything in sync across teams
