EDUC 750 Quiz 2 practice exam solution questions and answers Score for this quiz: 72 out of 75 According to the standard of poverty, poverty is defined in terms of what is normal in a given society at a particular time. absolute classical relative subjective At the nominal level of measurement, a variable's attributes are exhaustive when: all variables are in order. every case has one attribute. every case can be classified into one of the categories. all variables have a mathematical interpretation. Which type of validity is used when no clear criterion exists for validation purposes? Face Content Criterion Construct The absolute standard of poverty was developed by: Christine Hahn Patrick Allen Maryann Hayes Mollie Orshansky Which level of measurement is the most mathematically precise? Ordinal Ratio Interval Nominal Triangulation refers to the: precision of the level of measurement. use of two or more different measures of the same variable. phenomenon that occurs when a researcher recuses herself from a study. combined validity and reliability of a study. In a study of school attendance patterns for Girl Scout Troop 1234, gender would be considered a (n): variance. constant. ********** CORRECT ANSWER **************** factor. operation. Concurrent and predictive validity are types of validity. face content criterion construct Direct observation may be a primary or supplementary form of measurement in a study. True Data derived from historical documents or policy reports would be considered an unobtrusive measure. True Reliability is a prerequisite for measurement validity. True The ratio level of measurement identifies variables whose variables have no mathematical interpretation. False When evaluating sample quality, it is important to have a clear understanding about the: affiliation of the researcher(s). ethnicity of the population. population the sample is supposed to represent. publication history of the researcher(s). Which sampling method relies on a random selection procedure? Probability sampling Nonresponsive selection Reactive selection Nonprobability sampling Individual members of a sample whose characteristics are being measured are called: elements. sampling frame. enumerators. sampling units. The larger the , the less the findings. population; reliable sampling error; generalizable enumeration; valid sampling frame; consequential What is the primary limitation of cluster sampling compared to simple random samples? The sample is not representative of the population. The sampling error is greater. There is too much homogeneity. It is only a one-stage procedure. Which type of sampling ensures that the sample represents certain characteristics in proportion to the population? quota random purposive snowball How many steps are involved in systematic random sampling? Two Three Four Five Completeness and saturation are two tests involved in sampling. quota random purposive snowball When may sampling be unnecessary? When studying inanimate objects. When all units in the population are identical. In studies involving human subjects with the same descriptors. In studies involving precise variables. Any single random sample can be thought of as just one of an infinite number of random samples that, in theory, could have been selected from the population. True Understanding sampling distributions is the foundation for understanding how statisticians can estimate sampling error. True Choosing sites on the basis of their fit with a typical situation helps increase the generalizability of the sample True Quota sampling does not use a random selection procedure.
