Research Methods Final
Identify the four levels of measurement in order of providing less information to more information. What are the advantages of and/or contributions to research that using each type of measurement makes?
1. Nominal - they use catergories that vary in quality but not in amount 2.Ordinal- used by researchers when in need for inherent order 3.Interval -can be rank-ordered; having equal difference between categories 4.

A __________________ is the entire set of elements (e.g., individuals, cities, states, countries, prisons, schools, etc.) in which a researcher is interested.
Population
Explain and provide two examples each of probability sampling and nonprobability sampling. Why would a researcher use one over the other?
Probability sampling is a sampling technique used to gather information from a larger population based on the probability. It must be a random sample. an example would be to place m&m's in a hat and draw out one m&m and record which color you get each time. Nonprobability sampling is a subset of the population that represents the whole population. an example would be Love me nots, each time you are gaithering a subset response based off one orginal flower. Researchers would want to use probability sampling over nonprobability sampling because it is more realiable and unbiased.

Ratio
High school seniors in a small town are asked a series of questions to measure the frequency of their drinking and driving. The students give consistent answers to the series of questions, but police records indicate that drinking and driving is much more common than indicated by the students' responses. This suggests that the measure of frequency of drinking and driving is:

Ahlin and Connell believe that age of first cigarette consumption is associated with later criminal involvement. Specifically, they believe the earlier the first cigarette consumption was, the more criminal activities a person would commit later on. Please write a research hypothesis (1 point) based on their belief and identify the independent variable and its level of measurement (2 points) and the dependent variable along with its level of measurement (2 points) of Ahlin and Connell's research statement.
The earlier in age someone smokes a cigarette, the more likely they are to engagde in criminal activities later on in life. The dependent varibale is the the criminal activitiy later on. The level of measurement is nonimal because we are figuring out a yes/no question. Did the person who smoked commit criminal activity (yes/no). The independent varibale is the person who smokes a cigarette or not. The level of measurement is ordinal because we want know whether or not they smoked as well as there age.
