Importance of Quantitative Research in Different Fields and Nature of Variables Flashcards
to discover solutions to issues in educational research most especially in terms of assessment, program evaluation, evaluation, and statistics
Education
to assess techniques and strategies that will help businessmen in their decision-making practices
business
to investigate methods or approaches that will enhance one’s style and creativity

Information and Communication Technology
to improve the management of fisheries and conserve the aquatic population
Agriculture and Fisheries
to improve the effectiveness of a newly developed medicine, treatment, or approaches in addressing health problems
Science
is a characteristic or attribute of interest in the research study that can take on different values and is not constant. ________ may be straightforward and easy to measure including characteristics such as gender, weight, height, age, size, and time.
Variable
Kinds of Variables
DEPENDENT AND INDEPENDENT
is the variable manipulated or changed by the researcher. The __________ affects or determines the values of dependent variable.
independent variable
is sometimes referred to as the outcome variable because the resulting outcome of manipulating the independent variable is typically the focus of the research study. The ______________ is the one that the researcher is attempting to predict or explain.
dependent variable
are numerical which represents a measurable quantity. Some of the examples are time, height, weight, and number of population.
Quantitative Variables
Two Types of Quantitative Variables
Discrete Variables
Continuous Variables
are countable which have certain number of values. Some of the examples are number of students in a class, number of needle punctures, and money in your pocket.
Discrete Variables
are referred to interval variables which are measured in ranges and can be denoted by non-whole numbers. It can have positive or negative values.
Continuous Variables
are special type of continuous variables which cannot have a negative value.
Ratio variables
are also known as categorical variables. Their values do not result from measuring or counting. Some of the examples are religion, blood type, profession, and color.
Qualitative variables
Two Types of Qualitative Variables
Dichotomous variables
Nominal variables
have only two distinct categories or values. Some of the examples are True or False, Yes or No, and Male or Female
Dichotomous variables
are the most basic level of measurement. These are variables that have two or more mutually exclusive and exhaustive categories. However, these categories cannot be ordered. Some examples of nominal variables are marital status, blood type, hair color, citizenship, mode of transportation, and source of income.
Nominal variables
have a logical numerical sequence or order. It also refers to a position in a series. Variables with numerically relevant categories are called ordinal variables. An example may be asking someone how often he or she eats foods in the restaurant – their response options are Very often, Frequently, Sometimes or Never.
Ordinal Variables
are just like any variable which are not categorized as a dependent or independent variable in a study. It can also refer to any variables that you are not intentionally studying in your experiment or test.
Extraneous Variables
