Experimental Design:

  1. Observational Study: This kind of study is conducted over an extended period. Without altering the situation, it analyzes and monitors the relevant factors. The volunteers who are put in 2 distinct contexts are monitored during the investigation to examine how social contact affects human behaviour. The participant’s state won’t alter, regardless of the ludicrous actions, it engages in during this time. In medical situations, doing this might be extremely harmful because it could result in death or worsening of the patient’s condition.
  1. Simulations: This approach imitates a real-world process or circumstance using mathematical, physical, or computer models. It is commonly used when replicating the actual circumstance in real life would be prohibitively expensive, risky, or impracticable. This approach is frequently used in engineering and operational research for educational reasons as well as occasionally as a tool to predict potential findings from actual research. Not all experimental research projects can use simulation as a method for data collecting. For a lot of lab-setting experiments studying chemical reactions, it is quite impracticable.
  1. Surveys: One of the most popular methods for collecting data is through surveys, which are intended to acquire pertinent information about a population to determine. A survey comprises a collection of studies the researcher has written and that which the research project is asked to respond. Respondents can get surveys both physically and online. Investigators have little control over the type of data that is gathered while conducting surveys since it relies on the participant.
