The data set of 2011 year-end book value per share for all companies listed on the New York Stock Exchange is an example of cross-sectional data. Cross-sectional data is a type of data that is collected at one point in time, from different units of analysis, in this case, all companies listed on the NYSE. Time-series data, on the other hand, refers to data that is collected over multiple time periods for a single unit of analysis. Therefore, the data set is not a combination of time-series and cross-sectional data, nor is it considered neither time-series nor cross-sectional data.
