We’ll use these statistics in the next section when we graph the scores add confidence intervals for the average.Įxcel has formulas for each of these and is smart enough that you can simply highlight an entire data column and it will calculate the statistics for you. Standard Error is useful in understanding how much potential error there is in sample statistics. In the image below we have included the common maximum, minimum and average along with a couple of additional statistics: Standard Error and 1.96 x Standard Error. Generating simple statistics for your survey data, (mean, maximum and minimum) is easy in Excel. Step 1: Calculate simple statistics (mean, max, etc.) for all questions We’re not going to attempt to do this in our Excel based survey data analysis plan. While there are various specialist text analysis engines ( Amazon, Microsoft) the only thing you can really do with Excel is searching for content. Practically speaking this is the most difficult type of data to analyse. Numbers: Also Called Ordinal dataĪ example survey question that creates Text data There are three different types of data a typical customer survey generates: 1. This is good news because there are only a few types of statistical approaches you will need and Excel supports all of them.
Are the responses for one question are correlated (potentially implies causes / is caused by) another question?.Are responses for different questions correlated?.Are you getting better or worse in any way?.Are the responses for one question changing over time?.Are the responses for this customer segment significantly different from the responses for that customer segment?.Are the responses for this question significantly different from the responses for that question?.Are responses different for different questions or segments?.
You will generally only want to know three types of things about your data: When analysing survey data there are surprisingly few different types of questions you need to answer.
Step 5: Test for Significant Differences with Student’s t-Test.Step 4: Plot Averages Over Time, with Error Bars.Step 3: Add Histograms of Each Question.Step 2: Graph Each Question and Add Error Bars.Step 1: Calculate simple statistics (mean, max, etc.) for all questions.With a little bit of insight, you can do almost everything the statistical packages can do in Excel.
#Data analysis with excel what is it used for how to
In this post, I’ll take you through how to analyse your survey data using the built in features of Excel.Įxcel is a very good tool to use for your analysis and has the benefit of being on almost everyone’s desktop. You can use the same techniques and approaches using the standard Excel package While there are many advanced statistical packages, you don’t need them to perform a detailed and comprehensive analysis of your survey data.
