Answer to Question 1

A key strength of economic and statistical analysis is the amount of data used. Small samples are not representative of the entire population. Therefore, the predictions of a model based on smaller samples may be only a very weak approximation of some real world phenomena and lead to inaccurate predictions. Using a larger sample, or in other words, a lot of data, strengthens the force of an empirical argument as the researchers can make more precise statements.

Answer to Question 2

B
