A marine biologist will collect data regarding the length and weight of each of 50 trout caught and released at five different l
ocations 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
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.
For a better, clear and unbiased sampling, choosing randomly might not allow for a biased sampling. Choosing in an alphabetical order might not give a representative of the whole hospitals both private and public, thus invigilator the conclusion of our hypothesis test.
