What is the aim of this investigation
An experimental investigation is a type of scientific study where researchers manipulate variables to observe and analyze the effect they have on outcomes. It involves setting up controlled conditions to conduct experiments, typically using a group of participants or test subjects. By manipulating and controlling independent variables, researchers can determine their impact on dependent variables and establish cause-and-effect relationships. For example, a researcher may investigate the effects of a new drug by administering it to one group while giving a placebo to another and comparing the outcomes.
On the other hand, a descriptive investigation seeks to observe and document characteristics, behaviors, or phenomena without manipulating variables or establishing cause-and-effect relationships. Descriptive investigations focus on collecting data through various methods such as surveys, interviews, observations, or analyzing pre-existing datasets. These studies are valuable for providing a detailed understanding of a particular subject or population, but they do not involve experimental manipulation. For instance, a researcher may conduct a descriptive investigation to explore the eating habits of a specific group by surveying their dietary preferences, without intervening or manipulating any variables during the study.
In summary, experimental investigations involve manipulating variables to establish cause-and-effect relationships, while descriptive investigations aim to observe and describe characteristics or behaviors without manipulating variables.
