Answer to Question 1

B
Experimental research is concerned with describing the nature of the relationship between variables (e.g., causal) rather than with describing the characteristics of the sample. This latter function is more characteristic of survey research.

Answer to Question 2

C
Chance favors all individuals equally; therefore the chances of being selected for the sample by chance are equal for all individuals in the population.
