Final Flashcards
With historical-comparative research one examines a different culture or period to better understand the social world. T or F
True
Quantitative data is empirical expressed as words, visual images, sounds, or objects. T or F
False
In longitudinal research the researcher examines the features of people or other units at multiple points in time. T or F
True
Field research is a type of quantitative research in which a researcher directly observers the people being studied in a natural setting for an extended period. Often, the research combined intensive observing with participation in the people’s activities. T or F
False
A social impact addy study is a type of applied research in which a researcher estimated the likely consequences or outcome of a planned intervention or intentional change to occur in the future. T or F
True
A time-series study is a type of longitudinal research in which a researcher gathers the same type of information across two or more time periods. T or F
True
The halo effect is an error often made when people use personal experience as an alternative to science for acquiring knowledge. It is when a person overgeneralizes from what he or she accepts as being highly positive or prestigious and let its strong reputation or prestige “rub off”onto other areas. T or F
True
A panel study is a powerful type of longitudinal research in which a researcher observes exactly the same people, group, or organization across multiple time points. T or F
True
Exploratory research is research in which a researcher identifies sources of social behaviors, beliefs, conditions, and events; documents causes; test theories; and provide reasons. T or F
False
Explanatory research is
Research in which a researcher seeks to test theories and addresses the question of why events or patterns occur in social reality

Quantitative data is empirical evidence in the form of numbers. T or F
True
Hubert Humbort wants to draw a sample of people in Michigan who own an authentic, imported espresso coffee maker. There is no list of the people, and there is no reason to believe that they know each other. What type of sampling should Hubert use?
Purposive sampling
According to the central limit theorem used in inferential statistics,
if you draw many random samples, the samples form a normal curve with the highest point of the distribution equal to the population parameter.
John Johnson used nonrandom sampling in his study of successful scientists. He knew most got excellent grades in high school and college, excelled in mathematics, and had a strong interest in science from a young age. For his study, he was interested in sampling those who were successful as adult scientists, but did poorly in high school, did average or worse in math classes, and showed little interest in science until they reached college or later in life. What type of sampling was he using?
deviant case
Professor Hangnail wants to study how people join a small extremist political organization dedicated to right-wing ideas. He first interviews recent recruits and asks who introduced him/her to the organization. He next interviews the named person and asked who introduced them to the organization, and so forth. This is
snowball sampling
If you use this, you do not give an exact estimate of the population parameter. Instead the range is from a little below and a little above your best estimate of the population parameter based on statistics about the sampling error from your random sample and how certain you want to be of an answer.
confidence interval
A law-like mathematical relationship that states: Whenever many random samples are drawn from a population and plotted, a normal distribution is formed, and the center of such a distribution for a variable is equal to its population parameter.
central limit theorem
A range of values, usually a little higher and a little lower than a specific value found in a sample. One can specify with a probability level the degree of confidence that the population parameter lies within the range.
confidence interval
A type of nonrandom sampling, especially used by qualitative researchers, in which a researcher selects unusual or nonconforming cases purposely as a way to provide greater insight into social processes or a setting.
deviant case sampling
A type of sample in which the sampling elements are selected using something other than a mathematically random process.
nonrandom sample
A characteristic of the entire population that is estimated from a sample.
parameter
The name for the large group of many cases from which a researcher draws a sample and which is usually described in broad, theoretical terms is population
true
Purposive sampling is a type of nonrandom sample in which the researcher uses a wide range of methods to locate all possible cases of a highly specific and difficult-to reach population

population
Probability proportionate to size or (PPS) is a type of nonrandom sample in which the researcher uses a wide range of methods to locate all possible cases of a highly specific and difficult-to-reach population.
false
Quota sampling is a type of random sample in which the researcher first identifies general categories into which cases or people will be selected, then he or she selects a predetermined number of cases in each category.
false
A random number table is a list of numbers that has no pattern, such that each has an equal chance of occurring. Researchers use it to randomly select cases and for other randomization purposes.
true
is a list of numbers that has no pattern, such that each has an equal chance of occurring. Researchers use it to randomly select cases and for other randomization purposes.
random number table
A random sample is a type of sample in which the researcher uses a random number table or similar mathematical random process so that each sampling element will have an equal probability of being selected.
true
A population is a smaller set of cases selected by a researcher from a sample, and from which the researcher generalizes to the sample.
true
A sampling distribution is a distribution of values created by drawing many random samples from the same population.
