1. What are some of the reasons why a census might be preferred to a sample and why a sample might be preferred to a census. A census takes far more time and resources to complete, even if it may be more accurate/ comprehensive than a sample. Census measure the entire population. When you conduct statistical research on a population you have two choices about how you would like to examine or survey the population. You could conduct a census, which is a survey, count or examination of all members or elements of the population. You could also conduct a sample, which is a survey, count or examination of a portion or part of the population. 2. What is the difference between a parameter and a statistic? What is a target population? A parameter is a number describing something about a whole population. A statistic is something that describes a sample and is used as an estimator for a population parameter. The target population is the entire group a researcher is interested in.
