Summary of what is or is not wrong in these statistical calculations
See the worksheet page for proof of work for each number. (Pg.2)
1. Box and whisker plot (height of the indigenous being in meters)
a. Values are out of sequential order.
b. Median number is incorrect.
2. Average weight of members
a. Wesley was looking for the average weight of the species but choose the median
(middlemost value) instead of the average (all values added up and divided by its total.)
3. Lt. La Forge geographical survey of biomes.
a. Survey contains the ordinal data but ordinal is a scale of data. Therefore, it would be
categorical data but when including the number of species, mineral content, and solar
radiation it becomes quantitative data.
