Question

The article listed each tablet’s manufacturer, price, battery life (hrs.), the operating system (Android, iOS, or Windows), an overall quality score (0-100), and whether or not it has a memory card reader. For parts a) – e) answer whether it can legitimately be considered a variable or not. If it is a variable, classify it as categorical (and if it is binary) or quantitative (and if it is provide units). If it is not a variable, explain why not. In order to decide whether the variable is legitimate, think about what the cases are and review the definition of a variable outlined in class. (You may erase the instructions to this problem if you need more space for your answers.)
