hiii
your answer is here !
Explanation:
An experimental group is a group in which members of the groups are exposed to independent variable manipulation.
The control group is a comparison group that is treated in every way like the experimental group except that the manipulated variable is absent in it.
Example: In the study by Latane and Darley, there were two experimental groups and one control group. The participants in the study were sent to three types of rooms. In one room no one was present (control groups). In the other two rooms, two persons were already seated (experimental groups). Of the two experimental groups, one group was instructed not to do anything when smoke filled in the room. The other groups was not given any instructions. After the experimental manipulation had occurred the performance of the control group measured in terms of reporting of smoke was compared with that of the experimental group. It was found that the control group participants reported in maximum members about the emergency.

Experimental and control group
Explanation:
A scientific experiment will use both experimental and control group data to compare and arrive at conclusions.
Experimental group: Participants who participate in the experiment. The independent variables undergo variations or changes among the participants of the experimental groups.
Control group: Participants who actually do not participate in the actual experiment or receive experimental treatment but influence the experiment. They are the comparison factors with which the experimental group is compared in a research
Example: While conducting the learning outcomes of a learning process by students in a class, the researcher sets up both a control group and an experimental group
The control group of students was provided some learning concepts by the teacher under normal classroom environment
The experiment group of students also was provided the same learning concepts by the teacher in the same classroom environment but some independent variables were introduced in between like; arrival of clerical staff, loud noise from the adjacent classroom, some program held in the ground outside the classroom for higher class students, and other situations aimed at disturbing the normal flow of the class.
The learning outcomes of both the groups were compared to conclude about the factors which influence a learning process to obtain desirable learning outcomes.
