There are several different types of scales. the person feels describes them best. From the BOAI … They are very intuitive, so don’t worry. Type # 1. From Concepts to Observations . The measurement scale needs to be very accurate to get the most valid and reliable results. Imagine that you are standing in a forest surrounded by trees. That means our attributes were not exhaustive. Before you collect data during a research study, consider carefully which of the 4 types of data you are collecting and how you will use them once you have them. Nominal measures are categorical, and those categories cannot be mathematically ranked. S. S. (Stanley Smith) Stevens 1906-1973 is best known in the social sciences for his work on levels of measurement. What are the four statistical scales of measurement and what variables do these measure? One way of looking at the way variables are measured is based on the In February 2010, the National Research Council convened a workshop to investigate the feasibility of developing well-grounded common metrics to advance behavioral and social science research, both in terms of advancing the development of theory and increasing the utility of research … But, if we listed only these attributes, people with gray hair wouldn’t fit anywhere.

Notice, however, that although you can use the ordinal scale to rank the subjects, there is some important data missing; the first smoker occupies a rank the same distance from the second smoker as the second smoker occupies a rank the same distance from the third smoker. Often we want to describe respondents in terms of social characteristics such as marital status, education, and age. In this famous article, Stevens argued that all measurement is conducted using four measurement levels. Chapter 4: Measurement and Units of Analysis 4.4 Units of Analysis and Units of Observation Another point to consider when designing a research project, and which might differ slightly in qualitative and quantitative studies, has to do with units of analysis and units of observation. Michigan State University MSU Libraries. 9.1 Qualitative research: What is it and when should it be used? Some research outcomes require accurate data which certain levels of measurement cannot give; thus inappropriate choice might result to inaccurate results. In physical science, the measurement needs to be very accurate and precise but in social science, the measurement cannot be as accurate and it is a lot more subjective. 88. to indicate what attribute the person feels describes them best, Mutual exclusivity- a person cannot identify with two different attributes simultaneously, Nominal- level of measurement that is categorical and those categories cannot be mathematically ranked, though they are exhaustive and mutually exclusive, Ordinal- level of measurement that is categorical, those categories can be rank ordered, and they are exhaustive and mutually exclusive, Ratio level- level of measurement in which attributes are mutually exclusive and exhaustive, attributes can be rank ordered, the distance between attributes is equal, and attributes have a true zero point, Variable- refers to a grouping of several characteristics. But, you might object, "political affiliation" and "religious affiliation"-and a host of other things social researchers are interested in, such as preju- dice or compassion-have some reality.

It involves identifying the specific research procedures we will use to gather data about our concepts. Latent Construct, Variable, Social Science, Unobservable, Instrument, Define, Microsoft Word, Track Changes, Compare Documents, Edit, Revise. Likert scales use numbers but only as a shorthand to indicate what attribute (highly likely, somewhat likely, etc.) Operationalization is the process by which researchers conducting quantitative research spell out precisely how a concept will be measured. 1.1 How do social workers know what to do? Empirical research in the social sciences requires both accurate and reliable measures. Broadly, there are 4 levels of measurement for the variables – 1. A variable measured on a nominal is one which is … Measurement in social science research 1. For example, the first stump may breach the water by 24 centimeters, the second by 26 centimeters, and the third by 28 centimeters. Remember, operationalization is only a process in quantitative research. In general, it is desirable to have a higher level of measurement (e.g., interval or ratio) rather than a lower one (nominal or ordinal). 89. Equal intervals: This means that a unit difference on the measurement scale is the same regardless of where that unit difference occurs on the scale. For example, hair color could be a variable because it has varying characteristics. Nominal Data. (e.g. A variable refers to a phenomenon that can vary. for example, jersey numbers in basketball are measures at the nominal level. Combining Measurement Operations. There is considerable debate and controversy over the possibility, desirability and practicability of measuring social capital, yet without a measure of the store of social capital, its characteristics and potential remain unknown (Durlauf 2002b [1]; Falk and Harrison 1998 [2]). level of measurement in social sciences. no ordering of the cases is implied.

Unlike with physical attributes such as height, weight, and volume, researchers cannot measure variables such as extraversion, intelligence, and self-image directly.
