Question

A marine biologist will collect data regarding the length and weight of each of 50 trout caught and released at five different locations in a given lake. Which type of visual representation would BEST represent the marine biologist’s data?

a bar graph comparing the largest trout caught at each of the five locations

a scale drawing of all trout caught regardless of location

a circle graph comparing the number of trout caught at each of the five locations

a scatterplot comparing the length and weight of each trout regardless of location

Answer 1

I think that the best visual representation that the marine biologist would use is utilising a bar graph. A bar graph is composed of bars residing in a coordinate plane. In addition to that, the visual representation would most likely be used since the average weight and length of each trout coming from 5 different locations is compared.
