Question:
What is the relationship between a sample and a population?
Answer:
A population includes every member within a particular group, whereas a sample is a smaller subset of a given population.
Question:
How do researchers use samples to make inferences about a population?
Answer:
Many times, it is not possible to collect data from every member of a given population. Thus, researchers will collect data from samples of a larger population and use the findings from these samples to draw inferences about the population as a whole.

Question:
Define inferential statistics
Answer:
Performed in order for researchers to make inferences and generalizations about populations based on data gathered from samples (e.g. calculations such as those used for hypothesis testing).
Question:
Define descriptive statistics
Answer:
Involves analyses that provide a way to summarize and describe data (e.g.mean, median, mode).
Question:
Why is it important that statistical methods are performed ethically?
Answer:
Statistics is a very powerful tool that allows large amounts of information to be communicated and understood concisely. However, if statistical methods or data collection are performed unethically or irresponsibly, it can skew the results of a study and very easily mislead others into believing claims that are not necessarily supported by evidence.
