#My2Cents - Before you do any kind of analysis, SPEND SUFFICIENT TIME CLEANING AND STRUCTURING YOUR DATA.
I’m sure everyone here will agree that data accuracy is imperative for action-worthy analysis. Data cleaning is often labelled as the “unsexy” part of the job but everything is waste until the accuracy of data is ensured. User behaviours are changing so rapidly these days that the timeliness of the data is also equally important.
As a freshly minted analyst armed with a folder full of certificates, one could be aching to use all kinds of fancy charts, scripts and ML algos. However, all that jazz will only make good music when the instruments are perfectly tuned.
