Can we measure qualitative variables?
We can use many different metrics to summarize quantitative variables, including: Measures of central tendency like the mean, median, and mode. Measures of dispersion like the range, interquartile range, and standard deviation. However, we can only use frequency tables and relative frequency tables to summarize qualitative variables. To ...
What are the roles of variables in the qualitative design?
Qualitative researches follow three basic steps when analyzing the data:
- Drafting and organizing data. This could be transcribing the interview, organizing field notes from observations or ensuring all documents used in the analysis are available.
- Categorizing data into themes. The qualitative researches identify the data by themes, coding data elements and creating categories.
- Presenting the collected data.
Is an ordinal variable quantitative or qualitative?
So, ordinal variables sit somewhere between quantitative and qualitative measures. They are numericalised and hence appear quantitative but they represent categories which essentially are qualitative. So which one are they? Strictly, they are qualitative. But have quantitative attributes that lend them to a limited set of quantitative manipulation.
What is qualitative variables and its examples?
A qualitative variable, also called a categorical variable, is a variable that isn't numerical. It describes data that fits into categories. For example: Eye colors (variables include: blue, green, brown, hazel). States (variables include: Florida, New Jersey, Washington).
What is meant by qualitative variable?
Qualitative Variables - Variables that are not measurement variables. Their values do not result from measuring or counting. Examples: hair color, religion, political party, profession. Designator - Values that are used to identify individuals in a table.
What is quantitative variable?
Quantitative variables are any variables where the data represent amounts (e.g. height, weight, or age). Categorical variables are any variables where the data represent groups.
What are 3 examples of qualitative variables?
Identify the qualitative variables and determine whether they are nominal, ordinal or dichotomous. In this example ID number, sex, age group, and educational level are all qualitative. Although ID number and age group are numeric, these values are used simply for grouping.
What is a qualitative example?
Qualitative data describes qualities or characteristics. It is collected using questionnaires, interviews, or observation, and frequently appears in narrative form. For example, it could be notes taken during a focus group on the quality of the food at Cafe Mac, or responses from an open-ended questionnaire.
What is qualitative and quantitative?
Quantitative data are data about numeric variables (e.g. how many; how much; or how often). Qualitative data are measures of 'types' and may be represented by a name, symbol, or a number code. Qualitative data are data about categorical variables (e.g. what type).

Quantitative Variables. As discussed in the section on variables in Chapter 1, quantitative variables are variables measured on a numeric scale. Height, weight, response time, subjective rating of pain, temperature, and score on an exam are all examples of quantitative variables.
What is an example of qualitative and quantitative variables?
Examples of quantitative characteristics are age, BMI, creatinine, and time from birth to death. Examples of qualitative characteristics are gender, race, genotype and vital status. Qualitative variables are also called categorical variables.
Is age a qualitative variable?
One question that students often have is: Is age considered a qualitative or quantitative variable? The short answer: Age is a quantitative variable because it represents a measurable quantity.
What are the types of qualitative variables?
Qualitative variables are divided into two types: nominal and ordinal.
How do you identify variables in a qualitative study?
When naming QUALITATIVE variables, it is important to name the category rather than the levels (i.e., gender is the variable name, not male and female). While the independent variable is often manipulated by the researcher, it can also be a classification where subjects are assigned to groups.
How do you identify quantitative variables?
Quantitative variables are any variables where the data represent amounts (e.g. height, weight, or age). Categorical variables are any variables where the data represent groups. This includes rankings (e.g. finishing places in a race), classifications (e.g. brands of cereal), and binary outcomes (e.g. coin flips).

What is nominal scale?
The word “nominal” means “name”, which is exactly what qualitative variables are. A nominal scale is a scale where no ordering is possible or implied (except for alphabetical ordering like New York, Washington, West Virginia or Chelsea, Edinburgh, London).
Is pop music qualitative or quantitative?
Pop music genre. Exponents. Tribe. As a general rule, if you can apply some kind of math (like addition), it’s a quantitative variable. Otherwise, it’s qualitative. For example, you can’t add blue+green (unless you’re in an art class — even then you “mix” them, you don’t add them!).
Is a dog a qualitative variable?
Breeds of dog are qualitative variables. How many dogs are quantitative variables. As a general rule, if you can apply some kind of math (like addition), it’s a quantitative variable. Otherwise, it’s qualitative.
Qualitative and Quantitative Variables: Overview
In statistics, a variable is an attribute of the sample population that is being studied. It can vary from member to member of the sample, and it can be just about anything. Color, size, height, weight, and any other attribute that can be measured or described can be a variable.
What is a Qualitative Variable Definition in Statistics?
The Qualitative variable definition in statistics is one that falls into descriptive categories, things that are not measured. Color, taste, smell, style, mood, and satisfaction are examples of qualitative variables. These variables are not measured with numbers but rather describe the quality of something.
What is a Quantitative Variable Definition in Statistics?
The quantitative variable definition in statistics is one that can be measured and assigned a numerical value. It describes a quantity instead of a quality. Quantitative variables are also called numerical variables.. Height, weight, age, speed, diameter, and the number of marbles in a bag are all examples of quantitative variables.
What is qualitative variable?
A qualitative variable is understood as any type of characteristic or category that serves to classify a plot of reality in several non-numerical values that allow assessing the presence of differences or fluctuations with respect to said characteristic between the different subjects to be analyzed.
What is the most common qualitative variable in scientific research?
Sex. Probably the most common qualitative variable in scientific research, at least when we analyze aspects related to behavior and human health. This variable has two values in its most traditional conception, or three if we take into account the existence of intersex people.
What is another nominal qualitative variable?
Another nominal qualitative variable can be blood group. Have group A, B, AB or O at its positive or negative levels it does not allow us to order or establish numerical relationships (who has A + blood does not have twice that of B +, for example).
Is marital status a qualitative variable?
Marital status. Like sex, marital status is another qualitative variable of a nominal nature, whose values establish a quality or property in which different people can be differentiated but without there being any numerical relationship between their values.
Is socioeconomic status a qualitative or quantitative variable?
Socioeconomic status. Like schooling, it is a qualitative ordinal variable: having a high socioeconomic level implies a higher degree of this variable than someone with a low level, although a numerical relationship cannot be established. 10. Position.
What are some examples of qualitative variables?
Examples include: Eye color (e.g. “blue”, “green”, “brown”) Gender (e.g. “male”, “female”) Breed of dog (e.g. “lab”, “bulldog”, “poodle”)
What are the two types of variables?
In statistics, there are two types of variables: 1. Quantitative Variables: Sometimes referred to as “numeric” variables, these are variables that represent a measurable quantity. Examples include: Number of students in a class. Number of square feet in a house. Population size of a city. Age of an individual. Height of an individual.
What is qualitative and quantitative research?
Both qualitative and quantitative research is based on the lifeworld, and all researchers use prejudices and pre-understanding in the research process.
What is qualitative research?
Qualitative research involves the studied use and collection of a variety of empirical materials – case study, personal experience, introspective, life story, interview, observational, historical, interactional, and visual texts – that describe routine and problematic moments and meanings in individuals’ lives.
What is the main point of Becker's research?
The main point is that the categories that the researcher uses, and perhaps takes for granted at the beginning of the research process, usually undergo qualitative changes resulting from what is found. Becker describes how he tested hypotheses and let the jargon of the users develop into theoretical concepts.
Why is understanding important in qualitative research?
It is not enough to identify correlations, make distinctions, and work in a process in which one gets close to the field or phenomena. Understanding is accomplished when the elements are integrated in an iterative process.
What is research in psychology?
Broadly, research refers to the activity performed by people trained to obtain knowledge through systematic procedures. Notions such as “objectivity” and “reflexivity,” “systematic,” “theory,” “evidence” and “openness” are here taken for granted in any type of research.
Is research process oriented?
Obviously, all research is process-oriented to some degree. The point is that the ideal-typical quantitative process does not imply change of the data, and iteration between data, evidence, hypotheses, empirical work, and theory. The data, quantified variables, are, in most cases fixed.
Is fieldwork qualitative or quantitative?
Although qualitative research does not appear to be defined in terms of a specific method, it is certainly common that fieldwork, i.e., research that entails that the researcher spends considerable time in the field that is studied and use the knowledge gained as data, is seen as emblematic of or even identical to qualitative research. But because we understand that fieldwork tends to focus primarily on the collection and analysis of qualitative data, we expected to find within it discussions on the meaning of “qualitative.” But, again, this was not the case.
