An explanatory variable is known as the factor in an experiment that has been altered by the investigator or the researcher. The researcher uses this variable to determine whether a change has occurred in the intervention group (Response variables). An explanatory variable is also known as a predictor variable or independent variable.
What is an Explanatory Study?
In this sense, explanatory studies can deal with both the determination of causes (post-facto research) and effects (experimental research) through hypothesis testing. Its results and conclusions constitute the deepest level of knowledge, according to author Fidias G. Arias.
What are the different methods of explanatory research?
The most popular methods of explanatory research: Literature research:It is one of the fastest and least expensive means of determining the hypothesis of the phenomenon and collecting information. It involves searching for literature on the internet and in libraries. It can of course be in magazines, newspapers, commercial and academic articles.
What are the characteristics of explanatory research?
Among the most important characteristics of explanatory research are: It allows for increased understanding about a specific topic. Although it does not offer conclusive results, the researcher can find the reasons why a phenomenon occurs.
What is the difference between secondary and explanatory research?
As you can often use secondary research, explanatory research is often very cost- and time-effective, allowing you to utilize pre-existing resources to guide your research prior to committing to heavier analyses. While explanatory research does help you solidify your theories and hypotheses, it usually lacks conclusive results.
What is the treatment explanatory variable?
In randomized experiments, one explanatory variable is the variable that is used to explain differences in the groups. In this instance, the explanatory variable can also be called a treatment when each experimental unit is randomly assigned a certain condition.
What is the explanatory variable in the study?
An explanatory variable is what you manipulate or observe changes in (e.g., caffeine dose), while a response variable is what changes as a result (e.g., reaction times). The words “explanatory variable” and “response variable” are often interchangeable with other terms used in research.
Which variable is the explanatory variable?
independent variable❖ The variable that is used to explain or predict the response variable is called the explanatory variable. It is also sometimes called the independent variable because it is independent of the other variable. In regression, the order of the variables is very important.
What are examples of explanatory variables?
Example: Height & Age The students want to use height to predict age so the explanatory variable is height and the response variable is age.
What is treatment and response variable in statistics?
The affected variable is called the response variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The different values of the explanatory variable are called treatments.
Is the explanatory variable The independent variable?
An independent variable is the variable you manipulate, control, or vary in an experimental study to explore its effects. It's called “independent” because it's not influenced by any other variables in the study. Independent variables are also called: Explanatory variables (they explain an event or outcome)
How do you identify the explanatory and response variables?
The response variable is the focus of a question in a study or experiment. An explanatory variable is one that explains changes in that variable. It can be anything that might affect the response variable.
What is another name for explanatory variable?
independent variableIf the independent variable is referred to as an "explanatory variable" then the term "response variable" is preferred by some authors for the dependent variable.
What variable is the response variable?
dependent variableThe response variable is also known as the dependent variable. In other words, the response variable depends on another factor, known as the independent variable, to cause change, or response, to it.

What is the purpose of explanatory research?
Its intention is to provide details where a small amount of information exists.
Why is explanatory research important?
Explanatory research allows researchers to find a phenomenon that was not studied in depth. Although it does not give a conclusion of such a study, it helps to efficiently understand the problem. People who conduct explanatory research, do so with the objective of studying in detail the interaction of the phenomenon.
Why is it important to do exploratory research?

Does secondary research provide conclusive results?
Although it does not offer conclusive results, the researcher can find the reasons why a phenomenon occurs. It uses secondary researchas a source of information, such as literature or published articles that are carefully chosen to have a broad and balanced understanding of the topic.
When to Use Explanatory Research
- Explanatory research is used to investigate how or why a phenomenon takes place. Therefore, this type of research is often one of the first stages in the research process, serving as a jumping-off point for future research. While there is often data available about your topic, it’s possible the pa…
Explanatory Research Questions
- Explanatory research answers “why” and “what” questions, leading to an improved understanding of a previously unresolved problem or providing clarity for related future research initiatives. Here are a few examples: 1. Why do undergraduate students obtain higher average grades in the first semester than in the second semester? 2. How does marital status affect labor market participa…

Literature reviews 2. Interviews and focus groups 3. Pilot studies 4. Observations 5. Experiments The method you choose depends on several factors, including your timeline, budget, and the str…
Step-By-Step Example of Explanatory Research
- Your explanatory research design depends on the research method you choose to collect your data. In most cases, you’ll use an experiment to investigate potential causal relationships. We’ll walk you through the steps using an example.
Explanatory vs. Exploratory Research
- It can be easy to confuse explanatory research with exploratoryresearch. If you’re in doubt about the relationship between exploratory and explanatory research, just remember that exploratory research lays the groundwork for later explanatory research. Exploratory research questions often begin with “what”. They are designed to guide future research and do not usually have conclusiv…
