What does it mean to control for individual variability? Question 23 options: It means that we are making a model for only a small set of the data, where we only include individuals that are almost identical values (such as only individuals in the same demographic group with the same income). It means that we create a model based on things that a manager has control over (i.e. we'd include only things we can control, such as the number of employees working at an individual time, but we wouldn't use variables that we can't control, such as time or temperature). It means that some people have higher values than others, which is what is causing errors in the model. It means we're creating a model that is detecting the general slope between X and Y after incorporating information about a "baseline" value for each individual in the data set, which is a achieved by individuals having multiple Y-values in the data set
