Theory chapter 2 Flashcards
What is Ordinal measurement?
Ordinal measurement are ranking from small to large numbers or assigning in an order way (numbers) to represent a score.
What is Interval measurement?
Interval measurement has all the properties of an ordinal scale but has intervals in between. It lacks a 0-point.
What is Ratio measurement?
Ratio measurement has all the properties of interval scales with a true 0-point.
What is Independent variable?
Independent variables are the values that can be changed in a given model or equation.
What is Dependent variable?
Dependent variables are the variables that result from the independent variables.
Give the definition of conceptual variables.
Conceptual variables are abstract variables described as the experimenter understands them or sees them.
Give the definition of operational variables.
Operational variables are the results of the process of operationalization and are used to define something in terms of process needed to determine its existence, duration and quantity.
What is a semantic differential scale?
A semantic differential scale is used to measure the meaning an item has for an individual.
What is known as Transforming scales?
Transforming scales: where the researcher conducts a research by using one scale and then compare to other data by using a different rating scale.
Define Simple Rating Scale.
Where the researchers ask their respondents to rate a list of items to show personal preferences from 1 to 10 scale.
Define Thunderstone Scale.
Thunderstone scales (known as Equalappearing interval scales) are typically used to measure the attitude towards a given concept or construct.
Define Guttman Scaling.
Guttman scales presents a number of items to which the person is requested to agree or not agree. This is typically done in a Yes/No dichotomous format.
What is Likert Scale?
Likert scale is where respondents may be offered a choice of 5 to 7 points (or even 9), pre-coded respondents with the neutral point (either agree nor disagree). It is used to allow the individual to how much they agree (or not) with a statement.
What is Nominal measurement?
Nominal data is when a researcher selects his subjects by name or category.
