Unit 2.4 - Research Designs Flashcards
What is a procedure?
It shows the details of how the study will be conducted. Every little detail counts.
What are the two types of comparisons?
Between subject designs and within subject designs.
What does the between subject designs refer to?
It has 2 or more groups. It includes a control and experimental treatment.
What does within subject design refer to?
It only has one group but two 2 or more time points.
What is a factorial design? Provide some examples.
It has a minimum of two independent variables and four groups. Examples of two independent variables: day or night and presence and absence of cannabis, dependent would be the outcome (car collision)
What is a true experiment? How are its levels of manipulation, cause and effect, generalizability, and ethical concerns?
Researchers have full control over independent variables. There is manipulation and a cause and effect. The generalizability is low and the ethical concerns are high as the researchers assign things.
What is a Quasi-experiment? How are its levels of manipulation, cause and effect, generalizability, and ethical concerns?
Researchers have some control over IV. There is some level of manipulation and cause and effect. The generalizability is moderate as there are more individual differences taken into account that is beyond control; it is more reflective of real life. It has moderate the ethical concerns - we do not have full control on assigning things.
What is correlation experiment? How are its levels of manipulation, cause and effect, generalizability, and ethical concerns?
Researchers have no control over IV. It is looking at police reports and data collections. There is no level of manipulation and cannot assert cause and effect (rather predict). Generalizability is high and the ethical concerns are low as people choose what they want and are not assigned.
