Question

A random number generator was used to choose one hundred students from the freshman and sophomore classes of a mid-sized university to participate in a study designed to increase student interest in pursuing internships and research opportunities at this university before their junior year. Using an alphabetical list of last names from the sample, the first 50 students were assigned to attend weekly hour-long meetings during which counselor’s from the university’s career center would discuss with them opportunities for employment and graduate school options. The remaining 50 students also attended weekly hour-long meetings during which various campus issues were discussed, but there were no graduate school or career options. At the end of the fall semester, the Consideration of Future Consequences (CFC) scale was administered to the students in both groups.

b)No,Random Assignment was not used.Random Assignment is when each member of the sample has an equal chance of being chosen in any group in a study.Since alphabetical order of Last names were used, those with last names starting with the initial alpabets could only be assigned to the first condition, not second.This is not completely random.
