Mar 25, 2020 · There are various types of scientific studies such as experiments and comparative analyses, observational studies, surveys, or interviews. The choice of study type will mainly depend on the research question being asked. When making decisions, patients and doctors need reliable answers to a number of questions.

They create a streamlined report of findings for future researchers.They're inexpensive.The group that receives the treatment, device or procedure being testedThe group that receives no treatmentThe group that receives a placeboThe group that receives a different dose or different treatmentAdvantages
1. Group sizes can be large. 2. They provide insights into possible relationships between variables. 3. They do not require extensive variable control. 4. The timing of events can be obtained. 5. They're less expensive than randomized controlled trials.
Disadvantages
1. You cannot randomize them. 2. Studies may be lengthy. 3. It can be difficult to control for variables. 4. Participants often know which group they're in, meaning the study isn't blind. 5. Outcomes may suggest correlative relationships, but causative relationships cannot be determined.
Advantages
1. They're inexpensive. 2. They're quick to conduct. 3. They require fewer subjects than other studies. 4. They're useful for studying the incidence and genesis of rare diseases.
Disadvantages
1. They often depend on records or subjects' memories, both of which can be inaccurate, to determine the amount of exposure. 2. It's difficult to identify controls. 3. The study is not blind, creating potential bias in group selection and outcomes. 4. The sample size may be small. 5. The results only apply to specific populations and aren't generalizable.
Advantages
1. They're quick and inexpensive. 2. They're safe for participants.
Disadvantages
1. They may be subject to researcher or subject bias. 2. It's difficult to create even groups. 3. They cannot determine cause-and-effect relationships.
Mar 26, 2024 · Scientific research can be categorized based on its purpose, methodology, and the nature of the study. Below are the primary types: 1. Based on Purpose. Basic Research: Focuses on understanding fundamental principles without immediate application. For example, studying the structure of DNA. Applied Research: Aims to solve specific, practical ...
The study design and consequent study type are major determinants of a study’s scientific quality and clinical value. Methods This article describes the structured classification of studies into two types, primary and secondary, as well as a further subclassification of studies of primary type.
- According to its Purpose. Theoretical Research. Theoretical research, also referred to as pure or basic research, focuses on generating knowledge, regardless of its practical application.
- According to your Depth of Scope. Exploratory Research. Exploratory research is used for the preliminary investigation of a subject that is not yet well understood or sufficiently researched.
- According to the Type of Data Used. Qualitative Research. Qualitative methods are often used in the social sciences to collect, compare and interpret information, has a linguistic-semiotic basis and is used in techniques such as discourse analysis, interviews, surveys, records and participant observations.
- According to the Degree of Manipulation of Variables. Experimental Research. It is about designing or replicating a phenomenon whose variables are manipulated under strictly controlled conditions in order to identify or discover its effect on another independent variable or object.
These study designs all have similar components (as we’d expect from the PICO): A defined population (P) from which groups of subjects are studied. Outcomes (O) that are measured. And for experimental and analytic observational studies: Interventions (I) or exposures (E) that are applied to different groups of subjects.

The type of study design used to answer a particular research question is determined by the nature of question, the goal of research, and the availability of resources. Since the design of a study can affect the validity of its results, it is important to understand the different types of study designs and their strengths and limitations.
