Classification Of Variables And Measurement Scales Ppt2 types and classification of variables 1) there are two main types of variables: quantitative and qualitative. quantitative variables represent numerical data while qualitative variables represent categorical or attribute data. 2) variables can also be classified as discrete or continuous depending on the type of numerical values they. Levels of measurement (another way to characterize data) qualitative data is either nominal or ordinal (only 2 options) two kinds of.
Types Of Scales Levels Of Measurement Example Of Statistical Levels of measurement nominal level the nominal type differentiates between items or subjects based only on their names or (meta )categories and other qualitative classifications they belong to; thus dichotomous data involves the construction of classifications as well as the classification of items. Variables are measurement using an instrument, device, or computer. the scale of the variable measured drastically affects the type of analytical techniques that can be used on the data, and what conclusions can be drawn from the data. there are four scales of measurement, nominal, ordinal, interval, and ratio. the least amount of information is contained in nominal scale data, while the most. The document discusses (1) the four levels of measurement nominal, ordinal, interval, and ratio, (2) types of variables such as independent, dependent, and constant variables, and how they can be classified as quantitative or qualitative, and (3) provides examples to illustrate nominal, ordinal, interval, and ratio levels of measurement. The next type of measurement scale that we can use to label variables is an interval scale. interval scale: a scale used to label variables that have a natural order and a quantifiable difference between values, but no “true zero” value.

This document discusses research methods, levels of measurement, types of data, and ensuring validity and reliability in measurements. it describes four levels of measurement nominal, ordinal, interval, and ratio and gives examples. nominal data involves categories without logical ordering. ordinal data has ranked categories but distances between variables are unknown. interval and ratio.
