A farmer gave two groups of chickens different types of chicken feed for a month to measure the effect on egg production. The lists give the number of eggs collected from each chicken in each of the two groups.
Group G: , , , ,
Group H: , , ,
Which statement correctly compares the median number of eggs collected for group G and the median number of eggs collected for group H?
Explanation
Answer: A. The median number of eggs collected for group G is equal to the median number of eggs collected for group H. Explanation: 1) For group G (8, 15, 19, 19, 24), there are 5 numbers. The median is the middle value, which is the 3rd number: 19. 2) For group H (15, 19, 19, 24), there are 4 numbers. The median is the average of the 2nd and 3rd numbers: . 3) Both groups have a median of 19. Common mistake: Some students may forget that with an even number of data points (like group H), the median is the average of the two middle numbers, not just one of them.
