By the way the statistical software program SPSS uses only three categories: nominal ordinal and “scale” where scale includes interval and ratio level variables By the way some books will simplify these four categories into something like “categorical” or “attribute” and “numerical” but let’s learn the “real way” instead

Types of Data: Quantitative vs Categorical Variables
Data is a specific measurement of a variable – it is the value you record in your data sheet. Data is generally divided into two categories: 1. Quantitative datarepresents amounts 2. Categorical datarepresents groupings A variable that contains quantitative data is a quantitative variable; a variable that contains categorical data is a categorical ...
Parts of The Experiment: Independent vs Dependent Variables
Experiments are usually designed to find out what effectone variable has on another – in our example, the effect of salt addition on plant growth. You manipulate theindependent variable (the one you think might be the cause) and then measure thedependent variable (the one you think might be the effect) to find out what this effect might be. You wil...

What are the three types of variables?

Variables are the factors, traits, and conditions you can modify and measure. You’ll find different variables in all types of subjects. But, the most common variables found in a science experiment include dependent, independent, and controlled. Check out what each is through examples. Independent Variable

What are the examples of variables?

Variables are used in many disciplines, perhaps the most common example is the “X” variable in mathematics, which is generally an unknown value that we must find. In programming, variables are a somewhat different concept. To understand the essence of computer variables we need to know a little about computer memories.

What is data or variables in statistics?

Ø Data is a set of values of qualitative or quantitative variables. Ø In biostatistics (also in statistics) data are the individual observations. Ø The scientific investigations involve observations on variables. Ø The observations made on these variables are obtained in the form of ‘data’.

What is individual variable in statistics?

The who is known as the individual and the what is the variable. Individual – a person or object that you are interested in finding out information about. Variable – the measurement or observation of the individual. If you put the individual and the variable into one statement, then you obtain a population.
