A data-driven service I use daily is Tumblr. If I were to store data for Tumblr in a spreadsheet, a row would be an individual post. The columns I’d include would be the number of likes, the number of reblogs, the date of the post, and the time of when the post was made/reblogged.

What mainly enabled me to get a hang of using them were the in-class assignments with provided instructions. And from using Tableau and Excel, I learned how…[Read more]

A KPI I use on a regular basis is the Wells Fargo app I have on my phone. It is specific because it tells me the amount of money I have in my bank account. It is measurable because if I purchase something using my card, the app shows me the amount of money deducted as well as the remaining money I have left in my bank account. It is achievable and…[Read more]

To be honest, I haven’t made any of these mistakes since I never used Excel prior to coming to this class. With this being said, I think number 3 (working on the database without doing a full backup first) is the most important to avoid. I’m pretty sure that most of us at one point forgot to save/backup an important document/data and ended up…[Read more]

Out of Stephen’s 8 principles, I believe that “Be Skeptical” is the most important principle. Most of us just accept whatever data we find first, and maybe it’s due to laziness or as Stephen states, “….exploring any further is too hard”.

In my opinion, the most important takeaway from last week’s discussion on bias and the signal problem is to always be conscious/aware of data and to analyze it. Bias is widespread, and it can make decision-making difficult. Moreover, it is important to thoroughly analyze data and question it instead of simply accepting it. An example of how I u…[Read more]

A piece of conventional wisdom I have heard/been told is to wait at least half an hour after eating before swimming to avoid cramps. To test this, a sample group of people would be needed. On one day they would consume the same meal and swim in a pool immediately after. On the next day, they would again consume the same meal and wait half an hour…[Read more]
