 08- EXPERIMENTAL RESEARCH


Definition

Experimental research is a kind of study that requires two variables: independent (unmanageable) and dependent (manageable). The first determines if the second one happens or not. The goal is to prove a hypothesis or a method never essayed before by carring out an experiment under control conditions. The results are documented and then it is concluded whether the hypothesis was true or false. Another reason to apply the experimental research is to measure the replicability of a situation and/or how much it differs in between occurences.

Characteristics

Experimental research:
- Controls the environment and conditions to which the dependent variable is exposed, frequently subjected to the independant variable.
- The results of the investigation can be reproduced as long as the same factors are introduced in the experiment.
- The same treatment is applied in all the attempts to verify the principles carrying the hypothesis are veridical.
- Groups are formed randomly to prove the manipulation was the reason for the outcome.



Main uses

* In medicine, the discovery of the effectiveness of treatments with drugs before mass application
* The creation of new food or drinks by mixing or restructuring existing biological and/or artificial components
* The finding of green energy sources to impulse today's appliances
* The weather forecast changes and their effects on wildlife

Advantages and disadvantages:

Pros:
- Results tend to be constant.
- The cause and the effect of the research can be detected straightforwardly.
- It permits creating a base for future experiments as the results turn into antecedents.
- The subject does not affect the outcome, so whichever ends up exposed to the independent variable will give the reaction.
Cons:
- Its use is questionable in medicine as it can compromise the participant's well-being.
- The process can be time-consuming, resourceful, and expensive.
- Without the intervention of qualitative inference, the results are devoid of objectivity and can be misinterpreted.
- As it is prone to human error, the validity of the experiment can be denied.

05-  CHECKLISTS Definition A checklist is an instrument to verify if certain actions or conditions are met or occur during an event. The compliance of such parameters are valued through indicators reflecting the main points to answer the research question(s). Although they are widely applied in investigation, they are mainly employed during audits and QA (Quality Assurance) in search of optimal conditions and standards monitoring. Their format may con as printouts or digital files. Characteristics A checklist: * Groups related information from the authour's viewpoint. * Specifies what is expected to achieve after filling each item. * Can be altered to fit in the necessities of the investigation. * Is frequently implemented many times to observe the changes in the behavior of the subject. Main uses * To keep under control the aspect or operation the Checklist applies to * To maintain the order and entirety of procedures * To leave evidence of an event or standards that support the p

  QUESTIONNAIRES 📋📊 Questionnaires are a commonly used data collection tool in research and surveys. They consist of a series of structured questions designed to gather information from respondents. Questionnaires can be administered in various formats, such as paper-based forms, online surveys, or face-to-face interviews. They are used in both quantitative and qualitative research to collect data from individuals or groups. CHARACTERISTICS 📑 Introduction : The questionnaire usually begins with an introduction that provides an overview of the purpose and importance of the study. It may also include instructions on how to complete the questionnaire and assure respondents about the confidentiality and anonymity of their responses. Demographic Information: Questionnaires often start with questions to gather demographic information about the respondents, such as age, gender, education level, occupation, or location. This information helps to analyze data based on different participant

  13- P ROJECTIVE RESEARCH Definition Projective Research is a type of study that describes, analizes, compares, interpretes, and proposes solutions to a problem in a specific geographic and theoretical area. Its purpose is to prepare a settlement to tackle a greater need—one affecting a certain group of people and that considers the phenomenon evolution. Nevertheless, the problem is not solved because the final objective is to provide made-in-advance action schemes. Therefore, theory remains essential since it backs up the fundamentals of the investigation. Characteristics - It proposes yet does not apply the propositions in the subject matter. - It gathers analytical, quantitative, and qualitative data for the explanation of the current situation and provides countermeasures against the obstacles to good performance. - It considers upcoming needs to devise tentative plans. - This study emphasizes the relations between subject matters and their causes for those interactions will coord
