Which is the most reliable scale of measurement?
The level of measurement or scale of measure is a classification that describes the nature of information within the numbers assigned to variables. American Psychologist Stanley Smith Stevens developed the most popular classification with four levels: nominal, ordinal, interval, and ratio.
Are test results nominal or ordinal?
Nominal data assigns names to each data point without placing it in some sort of order. For example, the results of a test could be each classified nominally as a “pass” or “fail.” Ordinal data groups data according to some sort of ranking system: it orders the data.
Which test is used for nominal and ordinal data?
The Mann-Whitney U test is most appropriate for an ordinal level dependent variable and a nominal level independent variable. An ANOVA is most appropriate for a continuous level dependent variable and a nominal level independent variable.
What are nominal interval, ratio and ordinal scales?
What are Nominal, Ordinal, Interval and Ratio Scales? Nominal, Ordinal, Interval, and Ratio are defined as the four fundamental levels of measurement scales that are used to capture data in the form of surveys and questionnaires, each being a multiple choice question . Each scale is an incremental level of measurement, meaning,
What does nominal, ordinal and scale mean in SPSS?

Which is the best definition of a nominal scale?
A nominal scale is the 1 st level of measurement scale in which the numbers serve as “tags” or “labels” to classify or identify the objects. A nominal scale usually deals with the non-numeric variables or the numbers that do not have any value.
Which is the best description of the ordinal scale?
Ordinal Scale The ordinal scale is the 2 nd level of measurement that reports the ordering and ranking of data without establishing the degree of variation between them. Ordinal represents the “order.” Ordinal data is known as qualitative data or categorical data.
