Anwar Sadat Shimul, are you sure that you want books on experimental research design? I ask because the design of experiments is really quite simple and could probably be found on a number of websites. Having said that, I think that the treatment of experimental designs in the following book is helpful:

Portney, L. G., & Watkins, M. P. (2009). Foundations of clinical research: Applications to practice (2nd ed.). Upper Saddle River, NJ: Prentice-Hall.

The authors wrote their book for health contexts, but the text is applicable, and authoritative, with regard to a range of other contexts.

All the best with your research.

Robert Trevethan, thanks for your comment and recommendation. Much appreciated.

Hello,

I would recommend the following book:

Creswell, J. W. (2014). Research Design: Qualitative, Quantitative, and Mixed Methods Approaches (4th ed.). Sage Publications Inc.

Chapter 8 covers quantitative methods including experimental research.

All the best,

Tahani

Tahani Aldahdouh Thank you.

One of the classics (and in libraries if you can get to those depending on covid restrictions) is Box, Hunter and Box ( https://www.amazon.com/Statistics-Experimenters-Design-Innovation-Discovery/dp/0471718130/ref=sr_1_1?dchild=1&keywords=box+statistics+design&qid=1594243766&sr=8-1 ). But as Robert Trevethan says, depending on your design it may simply be randomizing which condition 50 students are allocated into. However, for other situations it is more complex, like how you might match people prior to allocation (and then sometimes randomize folks within those matched sets to groups). Are you wanting the book to learn about experimentation in general or for a specific project?
