volunteer sample

Which of the following describes a quota sample? =people who respond to a mailed survey make up the sample all students who sign up for a study make up the sample 60% of the population is left-handed, so 60% of the participants chosen are also left-handed participants are selected from a local preschool class to represent preschoolers who live in the area

60% of the population is left-handed, so 60% of the participants chosen are also left-handed

An administrator at a local elementary school identifies that 24 classes are taught throughout the day at her school. From this list, she selects 12 classes and then randomly selects 10 students from each of those 12 classes to measures preparedness. volunteer sample quota sample simple random sample stratified random sample cluster sample

cluster sample

A researcher conducts a study on eating in a movie theater by asking patrons as they enter a movie theater if they are willing to participate in a study while they watch their movie. The researcher selects the first 50 women and the first 50 men who volunteer to participate in the study. volunteer sample quota sample simple random sample stratified random sample cluster sample

simple random sample

To determine why almost half of the residents at a local nursing home are not eating their full meals, a researcher obtains a list of all residents at the nursing home and separates the list into two subgroups: residents who eat their full meals and residents who do not. The researcher randomly selects 12 residents from each subgroup to be in her sample. volunteer sample quota sample simple random sample stratified random sample cluster sample

stratified random sample

A disadvantage of cluster sampling is that a portion of the population may be missed in the sample, giving the researcher a sample that is not fully representative of the population. t/f

t

In convenience samples the probability of an individual being chosen from the population cannot be determined, because individuals are not chosen randomly. t/f

t

Quota samples are similar to stratified random samples without the random selection from subsets of the population. t/f
