Below are four data sets and descriptions, given as a list or a table. State which are categorical (qualitative) data and which are quantitative data, and explain how you determined each. Also state what n is for each data set - the number of data points in the data set. Understanding what n is for each data set will be an important step to doing the analysis asked for in the later questions, so check in with your classmates in the Collaboration Thread about this! (Hint for determining categorical or quantitative: Once you have determined what n is for the data set, determine what the question is you are asking each data point. Is the answer to that question a number, or a category? If this data were given as a list of n data points, would it be a list of numbers or a list of words?) 1.
