1. A researcher wants to study the impact of a new teaching method. They measure student performance before implementing the method and then again after implementation on the same group of students. Which specific experimental design does this represent?
2. Which research design is characterized by collecting data from different groups of people, who vary on the factor being studied, at a single specific point in time?
3. What is a primary disadvantage of the Experimental Study Design?
4. A study that follows the same sample of individuals over an extended period, taking repeated measurements, is known as a __________ study.
