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 continuous variables?
Continuous variables are also known as quantitative variables. Continuous variables can be further categorized as either interval or ratio variables.
What are the two types of quantitative variables?
There are two types of quantitative variables: discrete and continuous. What does the data represent? Counts of individual items or values. Measurements of continuous or non-finite values. Categorical variables represent groupings of some kind.
Is a variable ordinal or continuous?
A general guideline for determining if a variable is ordinal vs. continuous: if the variable has more than ten options, it can be treated as a continuous variable. The following examples are ordinal variables: Other types of variables have interchangeable terms.
What are the types of variables based the data owned?
