Question

What is the distinction between​ cross-sectional data and​ time-series data?

Answer 1

Answer:

B. ​Cross-sectional data provides information about economic behavior at an instant in​ time, while​ time-series data provides information about how an economic variable behaves over time.

Explanation:

There are two types of data, transverse data and time series data. Cross-sectional data is data that exists at a single point in time. For example, data from an observational survey or sales from a firm. Time series data are data that require intertemporal analysis, such as a country's inflation and GDP data, which should be analyzed for evolution. In other words, time series data are analyzed in a manner dependent on the previous period. Current month's inflation depends on the previous month's inflation analysis.
