Blends can be very tricky not jsut for beginners but even for experts due their very nature of being difficult to see. In this video, I'm going to go through step by step when you should use a blend vs a join to help you bring your data together easier. To follow along, you can download the data set at the following link: https://drive.google.com/file/d/1lOgn... How do you know when you should use a blend vs a join? This can be a tricky question as it depends on the data set you're actually using and what you're trying to achieve....generally speaking anyway. What I typically look for when joining two data sets together is if they have unique values or duplicate values on the fields I want to join. If either one has a unique list then I automatically go for a join because I know duplicate values will not be generated resulted in incorrect values in my final answer (Explained more in the video). If they both have duplicates then I (most of the time) go for blends in order to preserve the original data. ---------------- SUBSCRIBE for new videos Tuesday-Thursday.
