In all fields of knowledge across the world, research is an essential tool. The use of research is that it expands the knowledge already present, validates the theories by researching them in-depth and makes people more aware of a thing. Everything that is used to conduct good research depends on the objectives, scope, and nature of the research question, which is very important to get accurate results.
The two most popular research approaches are descriptive research and experimental research. Only their names may convey the differences between these two approaches. In experimental research, the researcher controls the unimportant variables and manipulates an independent variable to see how it affects the dependent variable.
In descriptive research, no experiment with any variable is conducted; instead, the researcher takes a study prompt and investigates it completely at a specific moment in time. In order to choose the best research approach, it is critical for researchers to comprehend the distinctions between experimental and descriptive research.
In this article, you are going to learn the differences between experimental research and descriptive research. These two commonly used approaches are different from each other in many ways, from gathering data to getting the result. You’ll also discover how understanding these distinctions can be valuable when seeking our research paper writing help. In this article, you are going to know the differences in their purpose, methods, strengths, and limitations.
Definitions of Descriptive Research and Experimental Research
Descriptive Research
Descriptive research, as in the name, describes a phenomenon, a situation, an event, etc. This type of research observes the prompt entirely, records every change witnessed in the prompt during that specific point in time, and analyses the characteristics of that prompt to get a better understanding of things at a specific point in time. The aim of descriptive research is not to explain why something happened or how it happened; in fact, it provides a detailed, comprehensive overview of a subject and the relationship between variables at a particular point in time.
Experimental Research
Experimental is a scientific approach; in this methodology, the researcher does not describe things in detail, but the researcher conducts experiments with the variables. In an explanatory research, the researcher experiments with the independent variable and observes its effects on the dependent variable. In brief, this kind of research seeks to establish a cause-and-effect relationship.
One important point of experimental research that affects the conclusion is the control of the researcher over extraneous variables, such as the environment or conditions under which the study is conducted by the researcher. Experimental research is considered the gold standard in scientific research because it can provide evidence of causal relationships.
Primary Elements of Descriptive Research And Explanatory Research.
Now, here are some striking characteristics of descriptive research and explanatory research. The knowledge of these characteristics is very important to distinguish one type of research from another. The employment of the wrong research method can be detrimental to the entire research and especially to the findings obtained by it.
Primary Characteristics of Descriptive Research:
Objective
Descriptive Research
The objective of descriptive research is to provide a detailed account of what is happening and what exists at a specific point in time. In descriptive research, the researcher only gives an account of a particular event, condition, etc., without manipulating any variable and without conducting any experiment. In this, a thing is observed only, and that can be done by a researcher from a distance, too.
Experimental Research
The objective of experimental research is to investigate causal relationships between dependent variables and independent variables. In this research, the researcher manipulates the dependent variable and observes its effect on the independent variable. This kind of research aims to establish a cause-and-effect relationship between variables.
Nature of Data
Descriptive Research
In descriptive research, the data collection is often qualitative, but it can also be quantitative. In descriptive research, the data are collected by observations, interviews, and surveys.
Experimental Research
In experimental research, the data collected is quantitative data. In this kind of research, the data is measured and analysed statistically. To gather data in experimental research, the researcher conducts the research in a controlled environment so that the data cannot be affected by extraneous variables, and if the research is conducted in a natural setting, the researcher tries to control the extraneous variables. It ensures that the manipulation of variables is the primary factor influencing the results.
Methods
Descriptive Research
Common methods that are used in descriptive research are case studies, observational studies, surveys, and content analysis. In descriptive research, it is observed that there is no manipulation of variables, and the entire prompt is studied as it is and how it changes naturally at a specific point in time and gets a full description.
Experimental Research
The method of experimental research involves two groups: an experimental group and a control group. The independent variables of the experimental group are manipulated by the researcher, while the control group remains untouched by the researcher or is sometimes given a placebo. The key feature of experimental research is randomly assigning the participants. The reason is that if there is any difference, the researcher can be sure that the changes are due to manipulation only, rather than external factors.
Control or Manipulation
Descriptive Research
In descriptive research, the researcher does not make any manipulation or control of variables. In this kind of research, the researcher only documents the existing research and does not make any intervention.
Experimental Research
The manipulation of variables is the key feature of experimental research. The researcher in experimental research controls the environment and conditions so that it can be understood what the cause of the observed effect is. In this kind of research, the manipulation of variables is important to ensure the results are reliable.
Purpose
Descriptive Research
The purpose of descriptive research is to answer the questions of “what”, “when”, and “where”. It can be understood with an example: if a researcher is researching a particular kind of population, in this case, the population, the behaviour of the population, the prevalence of a particular phenomenon, or what the pattern that emerges from a set of data is, those questions are answered in descriptive research.
Experimental Research
As in descriptive research, the questions of “what”, “when”, and “where" are answered. In experimental research, the questions of “how” or “why” are answered. In this kind of research, a phenomenon occurs by manipulating the independent variable and observing how it affects the dependent variable. The research also answers why this situation occurred. The main purpose of experimental research is to focus on a cause-and-effect relationship.
Examples of Descriptive Research and Experimental Research
In the article above, you have gained knowledge of what descriptive research is and what experimental research is. After reading the definition, you became aware of the primary elements, or, you can say, characteristics, of descriptive research and experimental research. But to understand something better, examples are a necessity. Here are some examples of descriptive research and experimental research.
Descriptive Research
- A study on a particular region on the eating habits of teenagers who reside there.
- A company rolls out a new product, and a survey is conducted to examine the preferences of consumers.
- An analysis of age, education, and income—the demographic traits of a population of a particular region.
Experimental Research
- A study on investigating how different light levels affect the development of a plant.
- A clinical study investigating the effect of a new drug with that of a placebo
- A study was conducted on students to investigate how deprivation of sleep affects the academic performance of students.
The Strength of Experimental Research and Descriptive Research
Every type of research has some strengths, because without possessing these strengths, a thing cannot be useful. Experimental research and descriptive research both have their distinguishing strengths that make them more useful than the other.
Descriptive Research
- In descriptive research, the researcher provides a broad overview of the subject taken for study.
- One of the strengths of descriptive research is that it cannot be conducted in real-time or retrospectively.
- In descriptive research, many hypotheses are generated that can help many other researchers conduct studies in the future.
- A striking strength of descriptive research is that it explains a completely substantiated phenomenon that is difficult to control or manipulate in an experimental setting.
Experimental Research
- One of the most prominent strengths of experimental research is that it establishes or explains the cause-and-effect relationship between the variables.
- In an experimental research study, the researcher provides high internal validity as the researcher maintains control over outside variables that may adversely affect the variables that are going to be studied.
- To increase the reliability of the finding that they are not churned out by any mistake, it can be replicated under controlled conditions.
- The characteristic of experimental research of randomisation and controlled groups is the strength of experimental research, as they reduce bias and confounding factors.
Limitations of Descriptive Research and Experimental Research
For a researcher to be aware of the limitations, along with the characteristics and strengths of the type of research going to be employed for the study, is very important. If a researcher is not aware of the differences between the limitations of descriptive research and experimental research, some mistakes can be made that affect the entire study and the findings severely. Here are the differences between the limitations of descriptive research and experimental research.
Descriptive Research
- Descriptive research cannot establish and explain cause-and-effect relationships as can be done by experimental research.
- Descriptive research cannot explain how and why something happened; it cannot explain what is before the researcher.
- Descriptive research has the peril of being biased.
- The result that is drawn from descriptive research cannot be generalisable to other populations and other settings.
Experimental Research
- Some experimental research is conducted in the setting of a laboratory, which can cause a lack of external validity, as in this kind of research, the research does not mimic the real world.
- When human participants are involved in experimental research, ethical concerns may arise.
- In experimental research, sometimes the researcher finds it too complex to control all variables, and this can limit the applicability of the results.
- One more limitation of experimental research is that it can be resource-intensive, as it may require a large number of participants to achieve reliable results.
Wrapping It Up
Despite being two distinct study kinds, descriptive and experimental research are both highly beneficial and complementary to one another. The distinctions between the two forms of research have been explained to you in this text. An experimental study determines the cause-and-effect relationship between the variables, whereas descriptive research provides a detailed picture of a phenomenon.
This essay aims to educate you on the key differences between experimental and descriptive research, as well as their respective advantages and disadvantages. A researcher can select the most suitable research design for the study that will yield the most accurate and trustworthy results if they are fully aware of these distinctions.
