Question
In one research project, researchers compared two tutoring programs. Students were randomly assigned to one of the two tutoring programs.
The table below shows: Students who received tutoring program “Boost” scored, on average, a grade of 1.5 points higher than before they entered the tutoring program began, with a standard deviation of 0.5.
Students who received tutoring program “Enhance” scored on average a grade of 1.0 points higher than before they began the tutoring program started, with a standard deviation of 1.0.
In which program was there more variation in the increase in grades?
- FALSE: In the tutoring program “Enhance”, because the standard deviation is closer to the mean score there.
- FALSE: In the tutoring program “Boost”, because the standard deviation there is smaller.
- TRUE: In the tutoring program “Enhance”, because the standard deviation there is larger.
- FALSE: In the tutoring program “Boost”, because the standard deviation there is closer to the mean score.
