Types of Research
I Based on the research goal:
- Pure research
- Applied Research
-
Pure Research
- It is driven by curiosity, interest & intuition.
- No specific goal is planned.
- It is exploratory in nature.
- It is also called as Fundamental Research or Basic Research.
- The main is to advance knowledge and to identify/explain the relationship between variables.
- Here, very minimum usage of technology is seen.
- Funding required to carry out such research is usually very minimum.
- The work area in basic research is usually restricted with controlled variable.
- The outcome of pure research are in the form of:
- New Theories/Principles.
- New way of analyzing a phenomenon.
- It can act as base for applied research.
- The findings may have future implications.
- Application is universal with wide area coverage.
- In Ayurveda, all the Literary Studies, Works on Manuscriptology, Survey based Studies are coming under basic research.
- Examples:
- Comprehensive review of doshagati from brihatrayi.
- Conceptual analysis of shatkriyakaala from pathological perspective.
- Critical analysis of emerging disease “Covid-19” from an Ayurveda perspective.
- Critical Comparative study of various commentaries of Carakasamhita with reference to shareerasthana.
- Collation, Editing & Publication of unpublished Manuscripts related to Ayurveda.
-
Applied Research
- It is driven by a specific problem existing at a given point of time.
- Goal is preset by the researcher.
- It is descriptive in nature.
- Technology usage for such research is on a higher scale.
- Good Funding is required.
- Area of work is real life situations with many variables coming into picture.
- The application of applied research is usually for present time and may not be applicable in future.
- It usually is planned on the basis of results of pure research.
- The applied research has commercial value as new products/services/instruments are designed.
- In Ayurveda, all the Clinical Studies, Animal Experiments & Tools developing studies can be taken under Applied Research.
- Examples:
- Clinical studies to assess the efficacy of drugs by comparing with standard.
- Tool to assess prakriti of a person by preparing a questionnaire.
- Development of new instrument to administer surgical, parasurgical & pancakarma therapies.
.Major differences between Pure Research & Applied Research |
||
Parameter | Pure Research | Applied Research |
Pre-Research Mindset | No specific goal | Clear goal is set |
Main aim | Advancement of knowledge | Solve a particular problem |
Nature of Work | Exploratory | Descriptive |
Area Covered | Usually Theoretical | Mostly Practical |
Base | Out of curiosity & intuition | Derived from Basic Research |
Outcome | May have future implications | Usually designed for present |
Scope | Universal – Diverse Applications | Particular Field |
Commercial Outcomes | Nil | New Products/technologies/ services |
Technology Usage | Minimum | High |
Economy | Usually nil or very minimum | More funding is necessary |
Environmental Factors | Usually done in a controlled environment | Done in real-life environment where even unexpected variable may intervene. |
Publications | Only high quality works qualify for academic publications | Usually high percentage of acceptance for academic publications |
II Based on the type of variables chosen in research
- Qualitative Research
- Quantitative Research
- Mixed
-
Qualitative Research
- It deals with words and meanings while data collection & analysis.
- It is applied when concepts or thoughts need to be understood.
- It gives clear insights of the topics that are not well understood.
- This type of research is usually followed by taking interviews (open-ended questions), observational studies & literature reviews.
- This research can have certain biases like observer bias & recall bias.
- In Ayurveda, commonly followed qualitative research are literary reviews, Survey based studies.
- Examples:
- Comprehensive study of Tantrayukti in Brihatrayi
- Survey Study on Etiological factors leading to Kushtha in Coastal India.
- Survey study on Vegadharana leading to common diseases in today’s time.
-
Quantitative Research
- It deals with numbers & graphs while data collection & analysis.
- Theories or assumptions can be tested through this research.
- Common methods in quantitative research include experimental studies, observations with numbers, closed ended surveys.
- This research can have certain biases such as sampling bias & information bias.
- In Ayurveda, commonly followed quantitative research is experimental & clinical studies.
- Examples:
- Efficacy of a particular drug in various dosage forms.
- Immunogenicity effect of Ashwagandha & Guduci.
- Analysis of shareerapramana & relation with health.
-
Mixed Approach
In certain cases, both the methodologies maybe adopted one after the other or simultaneously to gain maximum data.
.Major differences between Qualitative & Quantitative Research |
||
Parameter | Qualitative Research | Quantitative Research |
Data | Words | Numbers |
Main Aim | Formulating Hypothesis | Testing Hypothesis |
Respondents | Few also sufficient | Requires large number |
Questionnaire | Open-Ended | Close-Ended |
Expressed in | Words | Numbers, Graphs & Tables |
Data Collection Techniques:
Certain methods of data collection can be common for both qualitative and quantitative research. But, few of them can be exclusive to one of them.
Qualitative Data Collection Tools:
- Interviews: Open-ended Questionnaire.
- Focus Groups: Discussion with group of people on a common topic.
- Ethnography: Observation of culture and behavior in a community.
- Literature Review: Survey of Published works.
Quantitative Data Collection Tools:
- Surveys: Closed-Type Questionnaire.
- Experiments: Different variables under controlled environment to establish cause-effect relationship.
- Observations: Subjects being observed in natural environment without modifying the variables.
III Based on Intervention
- Observational Research
- Interventional Research
-
Observational Research
- Here, the subjects are not given any input by the researcher.
- Researcher observes the subject as he/she is following in routine life over a period of time.
- It usually takes less time for participation.
- One subject can enroll for multiple observational researches simultaneously as there is no modifying variable.
- In Ayurveda, Survey based studies are commonly followed observational researches.
- Example:
- Study to analyze the effect of specific seasonal traditional food on the residents of that area.
- Study to compare ratrijagarana & effect on shukra dhatu.
-
Interventional Research
- It is commonly called as Clinical Research.
- It involves giving external input to the body such as medicines, activities, devices or procedures.
- Here, the participant has to undergo the process for a longer duration.
- A participant can enroll in only one interventional research at a given point of time.
- In Ayurveda, All Clinical & Animal based Researches come under interventional research.
- Example:
- Effect of madhumehari churna on diabetes induced mice.
- Efficacy of Ayurveda therapy in comparison to modern surgeries.
Phases of Clinical Research:
Phase I | Purpose: Safety ChecksTo determine how and where the drug distributes within the body Sample Size: Small Group of people around 20-80Healthy Volunteers.Even Animal Experiments can be considered under Phase I. Monitoring: Serious adverse events”— that is, any toxic, undesirable, or unwanted effect that causes death or danger to health, like a disability or permanent damage, birth defect, heart attack, or other serious medical condition. |
Phase II | Purpose: Right DoseEfficacy Sample Size Large Volunteers with disease.Usually, there is a control group which receives the standard treatment or placebo. Monitoring: By comparing the groups with standard protocol & with trial drug.This phase can last several months to years. |
Phase III | Purpose: Right DoseEfficacy Sample Size Large Volunteers with disease.There is a control group which receives the standard treatment or placebo. Monitoring: By comparing the groups with standard protocol & with trial drug.This phase can last several years. |
Phase IV | It is also called Post-Market Surveillance. Monitoring: Long term public safety and potentially serious adverse events.This phase can last several years. |

Parameter | Observational Research | Interventional Research |
Nature of Work | Not interfering in the routine life of subject | Subject is intervened with medicines/procedures/activities/devices. |
Duration of Research | Comparatively less | Usually for a longer duration |
Subjects | Can enroll to multiple observational research simultaneously. | Can enroll only to one interventional research at a given point of time.S |
Outcome | May have future implications | Usually designed for present |
Scope | Universal – Diverse Applications | Particular Field |
