Question

1. what is the experimental group?

Explanation:

In experimental research (often in fields like Psychology, Biology, etc.), the experimental group is the group of participants or subjects that is exposed to the independent variable (the factor being manipulated or tested) to observe the effect on the dependent variable. It is compared with the control group (which does not receive the independent variable or receives a standard/placebo treatment) to determine if the independent variable has a causal effect. For example, in a drug trial, the experimental group gets the new drug (independent variable), while the control group might get a placebo, and then researchers measure outcomes (dependent variable like symptom improvement) to see if the drug works.

Answer:

In an experiment, the experimental group is the group of subjects (people, organisms, samples, etc.) that is exposed to the independent variable (the factor being tested or manipulated) to determine its effect on the dependent variable (the outcome being measured). This group is compared to a control group (which does not receive the independent variable or receives a standard/placebo treatment) to assess whether the independent variable causes a change in the dependent variable.
