The value of good data and good big data
- Big data's a term people throw around a lot. At its core, big data is very important for analysis and it's a way people talk about having a lot of data. It's related to something called sample size. And the more data you have, the bigger the sample size is and the greater the likelihood that you'll be able to derive relationships between the data and identify trends. But more important than big data is good data. After all, no matter how much data you have, if the data isn't good, then your analysis won't be very good either. Good data has been collected consistently and properly. The units are consistent and there aren't gaps in the data. Having good big data is extremely valuable because it means you have a large sample size and high quality data. And performing analysis on that kind of data means you have a higher chance of identifying meaningful implications and making accurate forecasts.
