MODULE 11 STANDARDIZED MEASUREMENT IN EDUCATIONAL RESEARCH p. 65-66

In a study, a researcher ranks students in terms of their attendance from highest to lowest. Class attendance is measured at _______________ level.

an ordinal In this case, class attendance is measured at an ordinal level since in this circumstance students were arranged from highest to lowest, which is highly reflective of the ordinal measurement scale.

According to the module, which ordering of the four scales of measurement lists them from the lowest to highest level of quantification? Ordinal, interval, ratio, nominal Interval, ordinal, ratio, nominal Ratio, nominal, ordinal, interval Nominal, ordinal, interval, ratio

___________________refers to the act of measuring, which involves identifying the dimensions, quantity, capacity, or degree of something.

Measurement

________ is the process of assigning symbols or numbers to objects, events, people, or characteristics according to an established set of guidelines. measurement evaluation

Measurement involves using rules for assigning labels to objects or people, such as inches for determining height or pounds and ounces for weight.

Variables measured on the nominal scale, such as gender and race, are also sometimes referred to as " ________ variables." quantitative measurement ordinal categorical

categorical: Since gender and race are not considered quantifiable, they are typically considered indicators of categories and treated as categorical variables.

In ___________, ratio-level measurement is occasionally used. For example, the following table presents a subset of data resulting from a study comparing the annual income of individuals with different types of education degrees. If a participant's annual income was zero dollars last year that means they did not earn any money at all.

Scores on an attitude assessment Ratio Interval

interval Attitude assessments are reflective of the interval measurement scale as they can be ranked according to a top-to-bottom method, with equal distance between integers

Reading achievement test score measured using a standard score (derived from the number of items correct) ranging from 200 to 800 where the average person scores 500 Ratio Interval

interval Achievement scores are reflective of the interval measurement scale as they can be ranked according to a top-to-bottom method, with equal distance between integers

includes rank ordering and this additional characteristic: equal intervals or distances between adjacent numbers. nominal ordinal interval ratio

interval measuring scale

The third level of measurement, the______________, includes the rank-order feature of ordinal scales, with the additional characteristic of equal distances, or equal intervals, between adjacent numbers on the scale. In other words, the difference between any two adjacent numbers on the scale is equal to the difference between any two other adjacent numbers.

interval scale

Gender" variable is __________________ scale.

nominal Gender is an example of a categorical variable, which is reflective of the nominal measurement scale.

categorizes, labels, classifies, names or identifies types or kinds of things that can be quantified. nominal ordinal interval ratio

nominal measuring scale

The first level of measurement, the nominal scale, is the simplest form of measurement. A ____________ of measurement uses symbols, such as words or numbers, to label, classify, or identify people or objects.

nominal scale

A few examples of nominal scales or______ include gender, school type, race, political party, state of residence, college major, teaching method, counseling method, and personality type.

nominal variables

College majors" variable is ___________________ scale.

nominal: College majors enable researchers to categorize study participants, which is reflective of the nominal measurement scale.

provides rank order of objects or individuals from first to last or best to worst. nominal ordinal interval ratio

ordinal measuring scale

The _____ of measurement is a rank-order scale. For example, this scale of measurement is frequently used to determine which students will be accepted into graduate programs.

ordinal scale

Class rank" variable is ________scale.

ordinal: Class ranks detail how students are ranked in order from top to bottom, which is highly reflective of the ordinal measurement scale.

Time taken to complete a task Interval Ratio

ratio Although task completion has interval properties, it also has a true zero point thereby making it a ratio scale.

Number of errors made in a specified time period Interval Ratio

ratio While the number of errors has interval properties (a consistent equal interval), it is possible to have zero errors. It therefore has a true zero point and is reflective of the ratio scale.

includes rank ordering, equal intervals and this additional characteristic: an absolute zero point. which permits forming ratio statements

ratio measuring scale

the _________, is the highest level of quantitative measurement. The _______includes the properties of ordinal (rank order) and interval (equal distances between points) scales, plus it has a true zero point.

ratio scale

While interval measurement scales have equal intervals between adjacent numbers, they lack ________. rank in order feature quantitative measurement true zero point zero point

true zero point: A true zero point would indicate a complete absence of something, which is not a characteristic of interval measurement scales as the zero point is usually arbitrary.
