Question

Students were divided into two groups. in one group students were ignored when they talked without raising their hands. in the other group students were attended to in the teacher's usual manner. the independent variable in this experiment was

Answer 1

The independent variable in the described experiment is the difference in the teacher's response to students talking without raising their hands between two groups. It aims to observe the effect of this teaching approach on student behavior or learning outcomes by comparing the experimental group with the control group.

Step-by-step explanation:

In the described experiment, the independent variable is the teacher's response to students talking without raising their hands. One group of students was ignored, representing a change in the usual behavior of the teacher, while the control group received the teacher's usual attention. This approach is designed to test the hypothesis that the independent variable, which is the teacher's response, will have an effect on a dependent variable, such as student behavior or learning outcomes.

The process of distinguishing between the experimental and control group is crucial for an accurate experiment. It ensures that the experimental manipulation, i.e., the change in the teacher's response to unraised hands, is the only significant difference influencing the outcome. By analyzing the results, the researchers can determine if the manipulation of the independent variable has caused any observable changes in the dependent variable.

Answer 2

The independent variable in the given scenario above is the attention from the teacher. It is because the attention from the teacher does not need to depend on both groups in order to act, for an independent variable is not depended on other which could be described above.
