Quick Notes
When interpreting intercepts and slopes in the context of any linear regression modeling, your interpretation should include both of the following phrases: “we expect” (or functionally similar) AND “on average”
When you’ve fit a multiple linear regression model (i.e., > 1 predictor), your slope interpretations must also include the following: “all else equal” (or functionally similar)
I know it’s prescriptive and somewhat repetitive, but for your own sanity (& mine <3), please please include these statements in every interpretation you provide
