SQL in 60 Ep 3: Aggregate Functions: You need to know ⬇️ Comment “course” for my beginner course to learn all the basics for data analytics! Whether you’re summarizing user behavior, totaling revenue, or generating KPIs, functions like COUNT(), SUM(), AVG(), MIN(), and MAX() help you move from raw data to meaningful insights by summarizing data. Here are the ones you REALLY should know: ✅ COUNT() – count records ✅ SUM() – calculate total ✅ AVG() – find central tendency ✅ MIN() - identify minimum value ✅ MAX() – identify maximum value You can also use them with GROUP BY to slice data by dimensions (aka columns) like date, customer, or user_id— this will be the next video so stay tuned! 🥳 If you’re not comfortable with these yet, they’re one of the first steps to getting more comfortable in SQL! They’ll unlock so much more for you 🤩 Which is NOT an aggregate function? (Vote in poll) Comment “course” for my beginner course to learn all the basics for data analytics! #sql #dataanalytics #datascience #sqlserver #womenindata #womenintech
