How to analyze survey data

The results are back from your online surveys. Now, it’s time to tap the power of survey data analysis to make sense of the results and present them in easy ways to understand and act on.

In this guide, you’ll discover what survey analysis is, the different types of survey data you can interact with, and six steps to conducting effective survey data analysis.

Survey analysis is the process of turning survey data into results and actionable insights. Based on the information you gather from a survey, survey analysis will help turn that raw data into an outcome you can discuss. 

Gaining valuable insight from your data is always easier when you go into survey analysis with a plan. Understanding what you want to achieve with your analysis will help you analyze your survey data more effectively.

The questions you ask in a survey directly respond to the form of data you receive. Data can either be quantitative or qualitative. 

Quantitative data refers to numerical information. For example, in the Net Promoter Score® (NPS) survey, customers will respond on a scale of 1–10. With that in mind, all the information gathered will be numerical, providing quantitative data. This form of data is accessible for direct comparisons and statistical analysis.

On the other hand, qualitative data focused on non-numerical information. This survey research aims to uncover the “why” behind numerical data. For example, you could ask respondents why they chose the number they did, offering space for them to write a response. While qualitative data is harder to analyze, uncovering the story behind your data is vital.

Numerical data is fantastic for tracking progress over time. But, if you want insight into why someone responded the way they did, a follow-up question that will yield qualitative data is a great idea.

Here’s how you can understand the numbers and meaning behind your results. 

Before starting with survey analysis, you must ensure your survey data is usable. Cleaning your survey data means deciding which respondents to exclude from your analysis, removing low-quality responses, and eliminating duplicated responses.

Some responses may only have answered a small selection of your total questions, while others may have rushed through your survey without considering their answers. All of these cases would contribute to low-quality data, which may impact the accuracy of your final results.

Conducting a response quality analysis will help you identify survey responses that don’t fit your criteria. For example, if you’re collecting data related to customer sentiment, a response from someone who isn’t a customer wouldn’t be beneficial.

Preparing your survey data for analysis by making it readable, equally formatted, and sorted will give you a clean and clear data set to conduct analysis.

A top survey research question is your guiding force for a survey. These questions relate to your survey research objectives, which you should have made when setting a survey goal.

Before diving into the granular details of your data, begin with your top survey question. For example, if your question was, “Would people be interested in buying this new product?” then the following table of results is where you should begin.

As you can see, the vast majority of people responded positively. With that in mind, you can proceed with data from other questions to gather more information about this product.

Broader, top-level survey questions will help you locate primary opinions and ideas within your data. Once you’ve laid this foundation, you can move into more intricate parts of data analysis to respond to your research questions. 

Often, one of the best ways to better understand data is to break it down. Your business can use cross tabulations (crosstabs) to divide your data into smaller groups based on shared characteristics. For example, you could filter the data by responses from a specific background. You can filter, compare, and create rules to analyze data on each use segment.

Data filters are a powerful way of gaining comprehensive insight into your data. For example, if you wanted to know how a product fared with different groups, you could include demographic questions in your survey. As people choose their age group, you can instantly filter for responses from each group. Comparing these datasets would then show how much each age group likes your product, helping to spot outliers or unhappier demographics instantly.

You could filter by:

While qualitative data doesn’t yield the percentages or raw numbers you can use here, you can always use text analysis tools. By gathering written responses and putting them through one of these tools, you could create a sentiment analysis that shows how your customers feel. 

Converting raw data into insight involves proving statistical significance. After all, you must ensure your data shows a finding rather than just cherry-picking cases. Statistical analysis reveals whether the trends you observe are meaningful and what the data suggests when used with other datasets. 

There are several methods you can use to prove statistical significance:

Beyond raw analysis, other factors determine whether or not you have meaningful results. For example, the total number of responses and completion rates compared to your total sample size will suggest whether or not your results represent a statistically significant group.

Equally, it’s a good idea to consider the margin of error in your survey results. A margin of error reflects how closely your results mirror the entire population. A small margin of error will suggest you have high confidence in the accuracy of your results, while the opposite suggests your results could fail to represent the wider world. 

If you need more survey responses to add a level of authority to your survey results, SurveyMonkey Audience has you covered. 

Benchmarking is the process of comparing your results to other companies or industry averages. You can even benchmark your results against yourself with repeated survey experiments collecting data over different quarters or years. 

Businesses around the globe use customer experience benchmarking to determine how their customers perceive them compared to their competitors. 

By conducting a longitudinal analysis, you’ll discover how your survey results have changed over time. For example, if you host an annual conference, you could ask attendees to rate their satisfaction with the event using a conference feedback survey. If the average satisfaction rate decreases over time, you have an interesting entry point for further research.

You could couple the satisfaction question with an open-ended one asking people to explain their choice. This qualitative data will shed light on what may be causing the decreasing satisfaction, helping you take actionable steps to fix it. 

You can even track data for different subgroups. Say, for example, that satisfaction rates are increasing year over year for marketing staff but not for administrators. You might want to look at administrators’ responses to various questions to see if you can understand why they are less satisfied than other attendees.

Your survey data has the power to tell a story. Start with your top research question, outline your findings, and go from there. What did you want to find out? What did you learn from your data? What specific findings stand out or are particularly interesting?

Where possible, use visuals to support your report. Your readers won’t want to move through paragraph after paragraph of written numbers. A simple graph or word could summarize your results and let people intuitively understand what the data is saying. 

Now that you’ve analyzed your data and found statistical significance, it’s time to show the world. Creating a great report showcasing your findings is the final step of practical survey analysis. With this report, you can share your findings with colleagues, which can inspire change in your organization.

When conducting survey analysis, there are several common pitfalls that you can fall into. Here are some mistakes to avoid.

The most prominent mistake people new to research make when conducting survey analysis is confusing correlation with causation. Causation occurs when one factor directly causes another. Correlation, on the other hand, occurs when two factors move together but may not be related.

A great example of this is the effects of cold weather. Drinking hot chocolate and wearing mittens are correlated variables, as they both tend to go up and down together. However, one does not cause the other. They are both caused by a third factor: the cold weather.

Just because two factors move together does not mean they are related. Performing correlation analysis will help you identify the relationships between your data.

You could connect two data pieces with a tertiary motive if you confuse correlation and causation. 

As we mentioned, you can think of your survey results as telling a story. However, you could be missing the bigger picture when you cherry-pick data, that is, selecting key data points that validate your hypothesis.

When you set out to prove something with a survey, it can be frustrating when your data doesn’t line up. Perhaps some customers simply don’t agree with a key statement, or your data doesn’t show a statistically significant majority. Whatever you encounter, the last thing you should be doing is being hyper-selective about the data points you use.

If you’re having to pick and choose which data to use in your calculations, then you’re undermining the accuracy of your survey results.

SurveyMonkey knows better than anyone that conducting surveys and gathering results can be extremely exciting. That said, when you rush to calculate survey results, you could be overlooking important data that hasn’t yet been filled in. 

Surveys often need large pools of responses to increase your level of confidence in the data. If you rush to calculate results as soon as possible, you may have fewer responses than you need to prove statistical significance. 

Imagine if your survey results show that 100% of customers are interested in a new product feature. While that sounds amazing, if only one person responded to your survey, how confident can you be that your pool of responses really reflects your wider customer base?

The questions you include in your survey directly respond to the type of data and the quality of the data you receive. With that in mind, your survey data is only as good as your survey questions. 

Here are a few tips:

By enhancing the quality of the surveys you write and send out, you’ll naturally begin to collect higher-quality data.

There are many aspects of survey data analysis, from looking at your top results to slicing and dicing the data to reporting on the results.
