Dr. Fodor has found that when college sophomores at his university work in pairs to solve difficult Sudoku problems, they often resolve the problems more quickly and accurately than those who work alone

However, Dr. Fodor wishes to replicate his findings to generalize that working in pairs is more effective than working alone. In what two main ways would you suggest he replicate his findings, and in what ways should he go about conducting these replications?
What will be an ideal response?

Answer: Dr. Fodor should try to replicate his findings across people and situations. In order to replicate across people, he may choose to conduct his study using participants from other age groups, those who are not college students, and even participants in other cultures. To replicate in other situations, Dr. Fodor would want to assign different types of problems, such as word problems, or even examine tasks that pairs perform in a workplace setting.
