What is the response (Y) of interest and how is it measured? The response variable is the total number of flu cases, which is a continuous variable.

Are predictor variables mentioned in the problem statement? If so, how many and what are their measurement levels? The research questions mention state and date as variables by which flu activity should be visualized. State is a nominal variable and date is a continuous variable.

What are you being asked to deliver? A data description, an interval estimate, an answer to a question, or a predictive model? You are being asked to provide a descriptive summary of flu activity. Visualization is an effective way to display time dependent data. For the first research question, we are comparing the total number of flu cases reported by state and season. For the second research question, we are displaying weekly data for a single flu season for each state.
