Solution by Steps
step 1
To determine which major has a mean SAT score greater than the median, we look at the shape of the distribution
step 2
A right-skewed distribution typically has a mean that is greater than the median
step 3
The Anthropology major's distribution is right-skewed, indicating that the mean is greater than the median for Anthropology
step 4
To determine which major has a greater median SAT score, we compare the center values of the distributions
step 5
The Economics major's distribution is more symmetrical, suggesting that the median is near the center of the distribution
step 6
Since the Economics distribution is centered higher on the SAT score scale than the Anthropology distribution, Economics has a greater median SAT score
[question 1] Answer
For Anthropology majors, the mean SAT score is greater than the median. The Economics majors have a greater median SAT score.
Key Concept
Distribution Shape and Central Tendencies
Explanation
The shape of a distribution can indicate the relationship between the mean and median. A right-skewed distribution typically has a mean greater than the median, while a symmetrical distribution suggests the mean and median are close. The median is the middle value, so for a symmetrical distribution centered higher on the scale, the median will be higher.
