What are some examples of qualitative variables?
qualitative variables are variables that are focused on the “quality” or the physical information. For example, BLUE balloon, BROWN chair, STRIPED wall. quantitative variables are focused on the “quantity”, the numerical value of something. For example, THREE balloons, EIGHT chairs, FOUR walls. Hope this helped!
Can we measure qualitative variables?
Others allow us to see that there is a quality or not that we are observing, but they do not allow us to measure it (especially when we talk about abstract elements): these are the qualitative variables . Characteristics of this scientific concept
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.
How to determine validity in qualitative research?
- In qualitative research, the researcher cannot adopt an objective manner and hence he is unable to prove the validity by using statistical procedures. ...
- He needs to make sure that he has avoided personal biases to a minimum to establish the validity of the research.
- He should also use the most appropriate sampling technique to avoid the sampling bias.
What is an example of a qualitative variable?
Also known as categorical variables, qualitative variables are variables with no natural sense of ordering. They are therefore measured on a nominal scale. For instance, hair color (Black, Brown, Gray, Red, Yellow) is a qualitative variable, as is name (Adam, Becky, Christina, Dave . . .).
What is a 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 qualitative and quantitative variables?
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).
What are examples of quantitative variables?

What's the difference between quantitative and qualitative?
Quantitative data is numbers-based, countable, or measurable. Qualitative data is interpretation-based, descriptive, and relating to language. Quantitative data tells us how many, how much, or how often in calculations. Qualitative data can help us to understand why, how, or what happened behind certain behaviors.
What is the difference between qualitative and quantitative example?
Quantitative data is fixed and “universal,” while qualitative data is subjective and dynamic. For example, if something weighs 20 kilograms, that can be considered an objective fact. However, two people may have very different qualitative accounts of how they experience a particular event.

Purpose of Qualitative Variable
The purpose of using qualitative variables is to allow for comparisons to be made between different groups or to see how changes in one group may impact other groups. Qualitative variables are often used in research to study human behavior, as they can provide insights into why people behave the way they do.
What is qualitative variable?

Is a sports team a qualitative variable?from study.com
Qualitative variables, on the other hand, can be put in groups or categories. For this reason, they are also called categorical variables. Sometimes they are given discrete numerical values that are convenient for grouping. But these numbers are not useful in doing calculations such as average or standard deviation. For example, sports teams are put into divisions, such as Division 1, Division 2, etc. But these numbers are simply used for grouping, and would not be used in doing calculations. This makes sports team divisions an example of a qualitative variable.

What is Positivism in Research?
Positivism is a research philosophy. It studies the social world using a scientific approach. Positivism believes in using a scientific, systematic, and objective approach to study the social world. A research based on positivism in social sciences is similar to research methodology used in natural sciences.

What are qualitative and quantitative variables?
The Quantitative and quantitative variables Are properties that can change and whose fluctuation is observable in some way. In this way, qualitative variables speak of properties that can not be measured with numbers and the quantitative ones include those to which a numerical value can be assigned (Bonton, 2017).
Which branch of science is responsible for studying the behavior of qualitative and quantitative variables?
The branch of science that is responsible for studying the behavior of qualitative and quantitative variables is statistics. In this way, it analyzes the numerically measurable variables and the abstractions that can not be measured and whose estimation depends on the individual who perceives them (Statistics, 2013).
What are the two types of variables?

When an approved, salient, acceptable, or deficient test is rated, it is a qualitative ordinal?
When an approved, salient, acceptable, or deficient test is rated, it is a qualitative ordinal variable, since it is not assigned a numerical value to the result, but it is being given a place within a scale of Value (Mendenhall, Beaver, & Beaver, 2009).

The quantitative variables are classified as discrete and continuous, the first being those defined by a finite number of elements (1, 2, 3, ...
Why can't happiness be measured numerically?
This variable can not be measured numerically because it depends on the value that each person assigns. Happiness is a property that each individual feels subjectively and there is no tool to measure the degree of happiness that a person can feel.
Qualitative variables in statistics
Qualitative variables (also known as categorical variables) are variables that fit into categories and descriptions instead of numbers and measurements. Their values do not result from counting.
Types of quantitative variables
Quantitative variables are divided into two types: discrete quantitative variables and continuous quantitative variables. Details and differences between these two types of quantitative variables are explained hereafter.
Discrete quantitative variable
Discrete quantitative variables are quantitative variables that take values that are countable and have a finite number of values. The values are often but not always integers.
Continuous quantitative variable
Continuous quantitative variables are quantitative variables whose values are not countable.
