I am completing a multiple linear regression model for a group project. The group picked average salary broken down by year (from 2010 - 2020), sex, and education level. The screenshot shows how the data is currently set up in Excel. Does the data look ok to run a regression in Excel? And do the year need to be broken down in to dummy variables as well?
