Join Robin Hunt for an in-depth discussion in this video What is data analysis?, part of Learning Data Analytics.
- You hear about the growing need for data analysis, so what is data analysis? There's lots of definitions, but this is pretty close. I'll paraphrase. It's the process of inspecting, cleaning, transforming, and modeling data for business decision-making. So what is a data analyst? Well, it's a person who does data analysis, of course, but their whole job is to help find better answers for better decisions, and the world needs a lot of them. If you search for data analyst jobs, you'll see a wide variety of job descriptions, and they use words like data, calculations, and analysis.
Just know that a data analyst will likely work with various forms of data and with all sorts of tools that are made for data. One of the number one goals for a data analyst is to turn lines and lines of data into something easier to read and interpret and make it more meaningful. The saying "A picture is worth a thousand words" is never more true than a person who works with an analyst, and an analyst who's good at their job. There's a McKinsey feature on big data that shows that we have one and a half million managers lacking the skills they need to analyze and make decisions.
So it's likely you and your manager both need this course. Forbes says it best. We have a long way to go. Get yourself educated. You're in high demand. So then, what is analysis? In its simplest form, it's the transformation of lines and lines of data into something that makes more sense, delivered into visualization to make better decisions.
