Research is a systematic study carried out using scientific methods to develop new theories or alter existing theories. Research refers to 'go about seeking'. The prime objectives of the research are to discover new facts, update/alter existing knowledge, provide solutions to problems. There are various types of research which include:

• Pure/Fundamental/Basic Research: Research carried out to enhance human knowledge. Theoretical in nature. 
• Applied Research: Helps in solving actual problems. Practical oriented. Principles of fundamental research are used in applied research.
• Action Research: Involves immediate action to control the problem. Steps: Plan → Act → Observe → Reflect.
• Ex post-Facto Research: Also called After The Fact Research. eg.: CID officers investigating a murder. Here, the fact has already occurred, thus, variables cannot be controlled or manipulated.
• Qualitative Research: Studies qualitative aspects of the matter concerned. eg.: color, beauty, scent, etc.
• Quantitative Research: Studies quantitative aspects of the matter concerned. eg.: height, weight, length, temperature, etc.
• Historical Research: Studies past events.
• Descriptive Research: Provides a description of a particular event. 

Experimental Research: 

• It is a systematic and scientific approach to research on establishing causal relationships.
• It is designed for establishing cause and effect relationships between two or more variables.
• It investigates a hypothesis through experiments in a controlled environment where a variable is manipulated by the researcher and its impact is observed on the dependent variable.
• It tests the formulated hypothesis and uses the results to generalize to a larger population.
• It helps in establishing causal relationships among different events in the educational situation under controlled conditions
• There are four essential characteristics of experimental research: control, manipulation, observation, and replication

→ The correct answer is option 4 as in experimental research we can control variables. This ability to control a variable is also called the 'Law Of Single Variable'.  Imagine doing an experiment in the laboratory to develop a new cough syrup. While testing, we have the flexibility to control the proportion of ingredients to determine which combination of ingredients gives the best result.

• Experimental Research cannot be easily generalized as a cough syrup won't provide some kind of relief to all infected people.
• It can't be easily analyzed as it takes years to scientists to develop new theories.
• It cannot be easily planned as it is mostly a group effort and may require huge investments.
