Answer (1)
To improve the quality of results in an experimental design, it is essential to ensure that the study answers a clear question about cause and effect. A well-defined cause-and-effect relationship enhances the validity of the conclusions drawn. Other options like reducing sample size or introducing too many responding variables could compromise the reliability of the results. ;
