Categorical and Quantitative Variables | Statistics

We introduce categorical and quantitative variables, and categorical and quantitative data. We define these terms and see some of the nuance that comes with classifying data as categorical and/or quantitative. As we'll see, it isn't always obvious which type of data or variable we are dealing with. Not all numeric data is quantitative, and quantitative data can also be gathered/used in a categorical way. We'll discuss data in context, and how the intention of statistician can effect the type of data being gathered. #statistics #apstats

I have a question for you.

A 3-year longitudinal study was conducted to investigate the approval ratings for the mayor of New City among registered voters. In
2014 among 86, 748 registered voters surveyed, 58, 593 gave the mayor a favorable rating. In 2015 among 82, 523 registered voters surveyed, 52, 931 gave the mayor a favorable rating. In 2016 among 84, 169 registered voters surveyed, 55, 475 gave the mayor a favorable rating.
What type of variable study is this?
