10. Protecting history How can we help wood surfaces resist weathering, especially when restoring historic wooden buildings? Researchers prepared wooden panels and then exposed them to the weather. Here are some of the variables recorded: type of wood (yellow poplar, pine, cedar); type of water repellent (solvent-based, water-based); paint thickness (in millimeters); paint color (white, gray, light blue); weathering time (in months). Identify the individuals in this data set. Classify each variable as categorical or quantitative. 10. Individual (Title - what are we talking about?): Categorical Variable(s) Quantitative Variable(s)
