Resolved: The analysis here is wrong
All of the figures quoted by the instructor are wrong in this video. Because the source dataset contains rows representating summations (e.g East Asia & Pacific region, Heavily indebted poor countries, etc), you cannot just visualise % Total of World GDP without cleaning. For example, the end result shows US GDP is 2.93%, but it is actually around 24%. This is how an insight is incorrectly presented in business meetings, and will confuse beginners
Hi Dean,
You are right! Thanks for the valuable observation!
I need to correct this video because to be honest perhaps I missed this detail in the source data at the time of filming (that there are other subtotals inside) or may be I thought that given that this is geographical data, Tableau will be able to solve this taks on its own. Thank you!
Best,
Ned
