Sound confusing? DonвЂ™t worry! All will become clear by the end of this post. First, though, weвЂ™ll set the scene by briefly recapping the difference between descriptive and inferential statistics (as standard deviation is a descriptive statistic, while standard error an inferential statistic).

In this post, weвЂ™ll explain exactly what standard deviation and standard error mean, as well as the key differences between them. This is where statistics like standard deviation and standard error come in. In other words, how applicable are your findings? As part of your analysis, itвЂ™s important to understand how accurately or closely the sample data represents the whole population. In this case, it most likely wouldnвЂ™t be possible to collect the data you need from every single person living in that city-rather, youвЂ™d use a sample of data and then apply your findings to the general population.

When analyzing and interpreting data, youвЂ™re trying to find patterns and insights that can tell you something useful. Keep reading for a beginner-friendly explanation. What are they used for, and what do they actually mean for data analysts? Well, youвЂ™ve come to the right place. Perhaps youвЂ™ve come across the terms вЂњstandard deviationвЂќ and вЂњstandard errorвЂќ and are wondering what the difference is.
