Given below are two statements:

Statement I: The purpose of a blind study is to prevent the participants from figuring out what the experimental wants.

Statement II: Interaction between the experimenter and the participants is always beneficial in social science research.

In the light of the above statements, choose the correct answer from the options given below

The correct answer is Statement I is true but Statement II is false.

Analysis of Statement I:
Statement I states: "The purpose of a blind study is to prevent the participants from figuring out what the experimenter wants."
This statement is true. In experimental design, a single-blind study is conducted so that participants are unaware of whether they are in the control group or the experimental group. This minimizes demand characteristics and participant bias, ensuring that participants do not alter their behavior or responses based on what they think the experimenter expects or desires.

Analysis of Statement II:
Statement II states: "Interaction between the experimenter and the participants is always beneficial in social science research."
This statement is false. While interaction and rapport building can be important in qualitative research (such as interviews or ethnography), interaction is not always beneficial. In quantitative or experimental research, experimenter-participant interaction can introduce severe experimenter bias, observer effects, or demand characteristics, which compromised the objectivity and internal validity of the study. Therefore, stating that interaction is "always beneficial" is incorrect.

Conclusion:
Since Statement I is true and Statement II is false, the option stating "Statement I is true but Statement II is false" is the correct choice.
