How do you calculate parameters in a slope scenario?
Example 1. Data were collected on the depth of a dive of penguins and the duration of the dive. The following linear model is a fairly good summary of the data, where t is the duration of the dive in minutes and d is the depth of the dive in yards. The equation for the model is d = 0.015 + 2.915t
Interpret the slope: If the duration of the dive increases by 1 minute, we predict the depth of the dive will increase by approximately 2.915 yards.
Interpret the intercept. If the duration of the dive is 0 seconds, then we predict the depth of the dive is 0.015 yards.
Comments: The interpretation of the intercept doesn’t make sense in the real world. It isn’t reasonable for the duration of a dive to be near t = 0 , because that’s too short for a dive. If data with x-values near zero wouldn’t make sense, then usually the interpretation of the intercept won’t seem realistic in the real world. It is, however, acceptable (even required) to interpret this as a coefficient in the model.
