Answer to Question 1

ANS: D
The population is all the elements (individuals, objects, or substances) that meet certain criteria for inclusion in a given universe. The researcher must determine which population is accessible and can be best represented by the study sample. A sample is a subset of the population that is selected for a particular study. Being a subset, the sample is either smaller than the population or, very occasionally, equal in size to it; it cannot be larger.

Answer to Question 2

ANS: D
When conducting a quantitative study, the researcher attempts to use the most precise instruments available to measure the study variables.
