For instance, it will take a lot more sample to find statistically significant differences between groups if you are asking, “What month do you think Christmas is in?” than if you are asking, “How many miles are there between the Earth and the moon?”. In the former, nearly everybody...
Survey data analysis is all about making sense of the answers you get from surveys. It means taking the raw responses, organizing them, cleaning up any errors, and using statistics to find patterns and trends. The goal is to turn those answers into clear, useful insights that can help with...
