Calculating Correlation in Excel: Your How-To Guide



Microsoft Excel lets you do more than simply create spreadsheets — you can also use the software to calculate key functions, such as the relationship between two variables. Known as the correlation coefficient, this metric is useful for measuring the impact of one operation on another to inform business operations.

Not confident in your Excel skills? No problem. Here’s how to calculate — and understand — the correlation coefficient in Excel.

A correlation coefficient of +1 indicates a “perfect positive correlation”, which means that as variable X increases, variable Y increases at the same rate. A correlation value of -1, meanwhile, is a “perfect negative correlation”, which means that as variable X increases, variable Y decreases at the same rate. Correlation analysis may also return results anywhere between -1 and +1, which indicates that variables change at similar but not identical rates.

Correlation values can help businesses evaluate the impact of specific actions on other actions. For example, companies may find that as spending on social media marketing increases, so does customer engagement, indicating that more spending might make sense.

Or they may find that specific advertising campaigns result in a correlated decrease of customer engagement, in turn suggesting the need for a reevaluation of current efforts. The discovery that variables do not correlate can also be valuable; while common sense might suggest that a new function or feature in your product would correlate with increased engagement, it might have no measurable impact. Correlation analysis allows companies to view this relationship (or lack thereof) and make sound strategic decisions.

So how do you calculate the correction coefficient in Excel? Simple! Follow these steps:

1. Open Excel.

Step one: Open Excel and start a new worksheet for your correlated variable data. Enter the data points of your first variable in column A and your second variable in column B. You can add additional variables as well in columns C, D, E, etc. — Excel will provide a correlation coefficient for each one.

In the example below, we’ve entered six rows of data in column A and six in column B.

6. Define your data range and output.

Now define your data range and output. You can simply left-click and drag your cursor across the data you want to select, and it will auto-populate in the Correlation box. Finally, select an output range for your correlation data — we’ve chosen A8. Then, click “Ok”.

7. Evaluate your correlation coefficient.

Your correlation results will now be displayed. In our example, values in column 1 and column 2 have a perfect negative correlation; as one goes up, the other goes down at the same rate.

The Excel Correlation Matrix

Excel correlation results are also known as an Excel correlation matrix. In the example above, our two columns of data produced a perfect correction matrix of 1 and -1. But what happens if we produce a correlation matrix with a less ideal data set?

Here’s our data:

excel correlation matrix: data

And here’s the matrix:

excel correlation matrix: result

Cell C4 in the matrix gives us the correlation between Column 3 and Column 2, which is a very weak 0.01025, while Column 1 and Column 3 yield a stronger negative correlation of -0.17851. By far the strongest correlation, however, is between Column 1 and Column 2 at -0.66891.

So what does this mean in practice? Let’s say we were examining the impact of specific actions on the efficacy of a social media campaign, where Column 1 represents the number of visitors who click through on social advertisements and Columns 2 and 3 represent two different marketing taglines. The correlation matrix shows a strong negative correlation between Columns 1 and 2, which suggests that the Column 2 version of the tagline significantly decreased overall user engagement, while Column 3 drove only a slight decrease.

Regularly creating Excel matrices can help companies better understand the impact of one variable on another and determine what (if any) negative or positive effects may exist.

The Excel Correlation Formula

If you prefer to enter the correlation formula yourself, that’s also an option. Here’s what it looks like:

excel correlation formula

X and Y are your measurements, ∑ is the sum, and the X and Y with the bars over them indicate the mean value of the measurements. You would calculate it as follows:

  • Calculate the sum of variable X minus the mean of X.
  • Calculate the sum of variable Y minus the mean of Y.
  • Multiply those two results and set that number aside (this is the first result).
  • Square the sum of X minus the mean of X. Square the sum of Y minus the mean of Y. Multiply those two numbers.
  • Take the square root (this is the second result).
  • Divide the first result by the second result.
  • You get the correlation coefficient.

Easy, right? Yes and no. While plugging in the numbers isn’t complicated, it’s often more trouble than it’s worth to create and manage this formula. The built-in Excel Toolpak is often a simpler (and faster) way to pinpoint coefficients and discover key relationships.

Correlation ≠ Not Causation

No article about correlation is complete without a mention that it does not equal causation. In other words, just because two variables rise or fall together doesn’t mean that one variable is the cause of the other variable’s increase or decrease.

Consider a few very strange examples.

excel correlation matrix: correlation not causation

This image shows a near-perfect negative correlation between the number of pirates and the global average temperature — as pirates became more scarce, the average temperature increased.

The problem? While these two variables are correlated, there’s no causal link between the two; higher temperatures did not reduce the pirate population and fewer pirates did not cause global warming.

While correlation is a powerful tool, it only indicates the direction of increase or decrease between two variables — not the cause of this increase or decrease. To discover causal links, companies must increase or decrease one variable and observe the impact. For example, if correlation shows that customer engagement goes up with social media spending, it’s worth opting for a slight increase in spending followed by a measurement of results. If more spending leads directly to increased engagement, the link is both correlated and causal. If not, there may be one (or more) factors that underpin the increase of both variables.

Keeping Up with the Correlations

Excel correlations offer a solid starting point for marketing, sales, and spending strategy development, but they don’t tell the whole story. As a result, it’s worth using Excel’s built-in data analysis options to quickly evaluate the correlation between two variables and use this data as a jumping-off point for more in-depth analysis.

What Apple’s Vision Pro means for AR and VR marketing



What Apple’s Vision Pro means for AR and VR marketing

Apple’s Vision Pro. Image: Apple.

This week Apple announced the Vision Pro headset, available early next year. Here’s what we know so far about the device and what this means for marketers experimenting with AR and VR engagement.

“Spatial computing” and AR. The use cases demoed at Apple’s Worldwide Developers Conference (WWDC) show augmented reality (AR) experiences where users interface with a digital layer on top of their real-world environment.

What this means practically is that users will be able to select and run apps from menus they see floating in their living room, office or other real-world environment. They’ll use voice commands, subtle hand gestures and eye movements to manipulate these objects and apps.

VR. Users will also be able to select virtual environments and adjust how much of their display is taken up by those environments. This means that Vision Pro users will also have the capability to plug into full VR experiences should they so choose.

Media. Vision Pro users will be able to watch movies and other streaming content. The improvement with the Vision Pro over TV screens is that these shows can take up a user’s full field of vision on their headset display. Content made or adapted for this system can also take advantage of the Vision Pro’s “spatial audio” sound, which promises to make it feel like sounds are coming naturally from the environment around the user.

Why we care. Apple has held off on getting into the AR/VR space while Meta struggled over the last two years to get headsets and the “metaverse” to seem cool and get widely adopted. Marketers remember the watershed moment when Apple’s iPhone spawned the mobile marketing ecosystem, and therefore there’s good reason to wait until Apple throws their hat in the ring.

It’s also worth noting that many AR experiences already exist using smartphone apps. The Vision Pro will make AR wearable, and if done right, will make these experiences more intuitive with natural eye moments and hand gestures.

Dig deeper: What marketers need to know about the metaverse, Web 3.0 and NFTs.

Price point. The Vision Pro is priced at $3,499. To give some perspective, that’s about half the current price of Apple’s newest Mac Pro. Back in 1984, the first Macintosh started at $2,495, which is over $7,000 in 2023 dollars.

Consumers who buy the Vision Pro will be spending three times more than what an iPhone costs. Businesses that want to equip their employees with Vision Pros will have to invest sizable budgets on par with new laptops or other significant hardware upgrades.

Consumer and B2B adoption. Being able to watch popular shows might be a gateway for consumers to adopt the new device and begin to explore AR and VR applications. Another adoption strategy is for people who use VR at work to bring the devices home. This explains Meta’s push for using their Meta Quest Pro headset for videoconferencing and other business uses.

Apple’s WWDC presentation showed how the Vision Pro uses machine learning to create a lifelike 3D model of a user’s face so that users can videoconference without their headsets being seen. This might be a more acceptable alternative to virtual meetings using cartoony avatars.

“Businesses are at a point where they want to get started with VR technology,” said Rolf Illenberger, CEO of enterprise VR platform VRdirect. “People in the office are asking about it. What’s missing is a general decision about which ecosystem to use.”

The Vision Pro inaugurates a new operating system, visionOS and a new Vision app store, where users will be able to access an anticipated flood of AR and VR apps.

AR and VR in marketing. Businesses in a number of verticals are adopting or considering VR for training and safety initiatives, Illenberger said. Widespread adoption for more general uses like virtual meetings is still several years away.

AR will likely be the first channel to get enough users to be of interest to marketers.

“There is a logical progression from AR marketing to VR marketing,” said Darwin Liu, founder and CEO of ecommerce services company X Agency. ”One needs to take off before the other one can. I expect AR marketing to really take off in the next 2-4 years and VR marketing to become important in 4-7 years.”

When enough customers are using a specific VR ecosystem, it will be important for brands to create a presence within it. This is still a far cry from an interoperable “metaverse” where users can jump from space to space seamlessly and bring digital assets with them to spend on merchandise wherever they want to. The customers that use visionOS will be within Apple’s walled garden. The price to reach them will likely be a steep one.
