dragons 2
PROBLEM
I wonder if the median heights of green dragons tend to be taller than the median heights of red dragons back in the population of dragons on Dragon Island.
PLAN
I will take my random sample from the Dragon Island survey team. The sample size is 52 female and 60 male dragons. NZGrapher will generate a dot plot and a box and whisker graph so I can analyze and make a conclusion about which species of dragon is taller.

PLAN

ANALYSIS
Central Tendency:
The median height of green dragons is 6m and the median height of red dragons is 4m, a difference of 2m. This indicates that green dragons on average are taller than red dragons back in the population of dragons on Dragon Island.
SPREAD
The boxes (middle 50%) for male and female dragons are very similar in spread. Their ranges are also very similar. This indicates that there is the same amount of variation in the heights of male and female dragons.
CONCLUSION
Based on looking at my sample I am reasonably confident that back in the population of all dragons on Dragon Island that green dragons tend to be taller than the red dragons.
If I took another sample of dragons I would expect to get similar results, Green dragons will be taller.
