'Research Methods' Practice Quiz Chapter 8

. If a researcher cannot gain access to a target population, snowball sampling procedures can assist in locating participants.

. In regards to sampling procedures, if a researcher wants to generalize results to the total population of interest, then a purposeful sampling technique is the best approach.

. __________ sampling is a type of convenience sampling that occurs when participants continue to be selected until a certain number is obtained.

. __________ sampling a type of sampling that ensures everyone in the study population has an equal chance of being selected to participate in the study.

. __________ sampling is a type of sampling that subdivides participants into categories to ensure that representation will be drawn from those individual subcategories (such as dividing men by height and having a category for those under four feet tall).

. Sampling is a process where researchers select a portion of the total population to be included in their study (as opposed to studying the whole population of interest).

. The research method that describes the difference between the total population of interest and the actual study sample is referred to as:

. To conduct simply random sampling, the researcher requires a list of all possible subjects/objects from the total population of interest.

. If a researcher wants to make generalizations back to the total population, the best sampling strategy to utilize is a snowball sample.

. Sampling has its disadvantage to quantitative research because it prohibits the ability to utilize statistical procedures to analyze the data.

. A sampling frame is a list of all elements in the population to be studied.

. The two broad categories of sampling techniques are probability and nonprobability.

. The simple random sample is a sample from the population in which every member of the total population has an equal chance of being selected.

. Nonprobability sampling occurs when a researcher's goal is to study a specific sample of interest and is less concerned about making generalizations to the total population.

. The type of sampling technique will determine what statistical analysis options are available to the researcher.

. If a researcher chooses one specific agency to study (a purposeful sample), it is likely to be a __________ sample.

. Random digit dialing refers to a process of selecting participants for telephone surveys by generating the numbers at random.
