Quiz 7: Measurement Scales
Three basic question formats and its variations: The 3 fundamental question formats and its variations with examples are listed in Table 1. Table 1
Measurement: It is the process of determining the amount or description of a number of elements of attention to the investigator is experienced as the measurement. Questions are designed to pull together information and represented through measurement. Object: • Customers, advertisements, stores, and other constraints of attention to the investigator are known as object. Properties: • Properties are the characteristics or the specific features of an object used to differentiate it from another object. It is also recognized as attributes. • Only properties are measurable. • Properties are classified into two types: • Objective properties • Subjective properties • Objective properties are the physical attributes of an object such as gender and age. • Subjective properties are the unobservable attributes (mental constructs) of an object like opinion, attitude, and intention. Thus, measurement, objects, and its properties are described.
Operational definition: • A procedure used to measure the properties of an object is known as an operational definition. • The investigator uses operational definition to know which attributes to be assessed in a particular object. Examples for operational definition: a. The Likelihood of buying car X: Likelihood is the changes or probability of executing things in future. Operational definition for this example would be the percentage with which Mr. Y likes to buy a car X in the next year. 0%, 5%, 10%, 15%, 20%, 25%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%. b. Reading the newspaper: An operational definition for this example is which section of paper is used to read. ___Sports, ___National news, ___Politics, ___Local news, ___Weather report, ___Entertainment, ___World news. c. Attitude toward global warming: The operational definition for this example is presented in Table 1. Table 1 depicts the operation definition, which is the opinion or the level of acceptance to a belief by a human being. Table 1 Thus, the definition and examples for operational definition are described.
