Combined strategy is defined as a factorial study that combines two (2) different research strategies, such as Experimental and Non-Experimental or Quasi-experimental in the same factorial design.

In psychology, a combined strategy is a decision-making approach that involves the use of multiple strategies simultaneously to achieve a desired outcome. This approach is often used when a single strategy may not be sufficient or when different strategies may complement each other.

An example of a combined strategy is in education, where a teacher may use a combination of lecture-based teaching, interactive discussions, and practical exercises to improve students' understanding and retention of a subject. Another example is in sports, where a coach may use a combination of physical training, mental preparation, and team-building exercises to improve athletes' performance.

In healthcare, a combined strategy may involve the use of multiple treatment methods, such as medication and psychotherapy, to treat a patient's condition. Similarly, in business, a combined strategy may involve the use of multiple marketing and advertising methods to reach a broader audience and increase sales.

The success of a combined strategy depends on the effective integration and coordination of different strategies. It requires careful planning and execution to ensure that each strategy is contributing to the overall goal and not conflicting with each other.
