The Department of Mathematics at the College of Science held a seminar titled "One-Way Repeated Measures (RM-ANOVA) " presented by postgraduate student Hussein Abdul-Ali Abdul-Hussein. The seminar aimed to clarify the concept of a repeated-measures design (also called a within-subjects design). It refers to a type of experimental design in which the same subjects (or experimental units) are measured several times under different conditions (treatments) or at different time points. This means each participant provides data for every level of the independent variable (factor). It is often used in psychological, medical, and biological studies.
