Dear Grandma,
Happy New Year. You asked me what I do at my job. I might be able to use data science to help you find solutions in the grocery shops or at the cafe too.
I can help your favorite bakery to decide what the most popular flavors and colors of cupcakes are sold in different seasons through the year so they can maximize their revenue. (seasonality analysis & optimization)
I help your favorite cafe to test if they should use Starbucks or Costa coffee beans. I will interview the customers at the cafe to track their satisfaction on the latte without telling them which beans are used. I also need to make sure that I don’t write Kelvin’s name as Calvin on the form as I was 8 years old. (AB Testing & data accuracy)
I will help you to figure out what time during the week you should visit your favorite restaurant with the shortest wait so you don’t need to stand outside in the rain for more than 20 minutes. (analytics insights)
I can also help you understand when you should ask for discounts at the cafe based on the color of the barista Anne’s shoes during a week, because I have 95% confidence that she is in an absolutely good mood when she wears her favorite deep brown Chelsea boots. (correlation & causality)
I can analyze grandpa and your favorite foods, restaurants, movies, and travel destinations to predict if you two are a great matched. So far I can validate that things seem to work pretty well for 60+ years. (machine learning)
I can document the ingredients of the food for your breakfast, lunch and dinner in the past 2 months and guess what you might order for your birthday dinner this year. (predictive modeling)
Now you might know what I am working on every day. You can ask me any questions or help if you can’t decide between raspberry or chocolate flavor ice cream.
I wish you lots of health in 2021!
Forgive me for being such a nuisance.
Your Grand Daughter
