Question

For each of the following statements, please complete the following three tasks: Draw Campbell and Stanley Symbols (“R”, “X”, “O”). Identify the type of research design for each (A. Pre-experimental, B. Experimental, C. Quasi-experimental and D. Ex Post Facto). Comment on how likely you can draw a causal conclusion. He randomly selects 50 elementary school students who play chess and 50 elementary school students who do not play chess. He measures and compares the two group IQs.

Answer 1

The Campbell and Stanley symbol is : R O₁ X O_2.

The research design is Experimental

Based on the result of the data, that is if there is indeed an increase in IQ of the school students, it is highly likely to draw a causal conclusion.
