Measurement Basics
What is the definition of measurement in social science?
What is the process by which we describe and ascribe meaning to key facts, concepts, or phenomena?
What is the lowest level of measurement that categorizes data without any order?
What is nominal measurement?
What term refers to the extent to which a measure accurately represents the variable it is intended to.
What is Validity?
Who proposed the three categories of measurement that include observational terms, indirect observables, and constructs?
Who is Abraham Kaplan?
Which level of measurement allows for rank ordering but not for equal distances between attributes?
What is ordinal measurement?
What do we call the consistency of responses across items in a multi-item measure?
What is Internal Consistency?
What term describes the quality of being consistent in measurement?
What is reliability?
What level of measurement includes equal distances between values but lacks a true zero point?
What is interval measurement?
Which type of validity assesses whether a measurement accurately reflects the concept it intends to measure?
What is construct validity?
What is the difference between unidimensional and multidimensional concepts?
What is unidimensional concepts measure a single attribute, while multidimensional concepts involve multiple attributes?
Which level of measurement has a true zero point, allowing for meaningful ratios?
What is ratio measurement?
What is the term for systematic error that affects the measurement results?
What is bias?
What is a systematic procedure for assigning scores and meanings in measurement?
What is operationalization?
Why is it important to understand the level of measurement when analyzing data?
What is because it determines the types of statistical tests that can be applied?
How can researchers increase the validity of their measures?
What is by using established scales or developing new measures with stakeholder input?
