Aquarium 1 will hold 5 small fish for every 10 gallons of water. If there are 200 gallons in the tank, you can sent up a proportion:
5 small fish/10 gallons = x small fish/ 200 gallons
if you cross multiply, you get
10x = 200 × 5
10x = 1000
x = 100
100 small fish will be in 200 gallons of water.
Aquarium 2 will hold 8 large fish for every 40 gallons of water. A proportion can also be set up here:
8 large fish/ 40 gallons = x large fish/ 200 gallons
if you cross multiply, you get:
40x = 200 × 8
40x = 1600
x = 40
40 large fish will be in 200 gallons of water.
the ratio of small fish to large fish:
100 small fish: 40 large fish
(both are divisible for 10, and if you divide both of them by ten you get)
10 small fish: 4 large fish
you can reduce again, since both are divisble by 2
5 small fish: 2 large fish

The research error described above is an example of selection bias.
Selection bias takes place when, from a population of interest, a group of individuals is selected in order to construct a sample but without a proper randomization. The result is a sample which is not representative of the underlying population.
According to the example, the target population of the research comprises all students but the sample only includes boys. Hence, selection has not been random because it followed a gender criteria, and the results obtained using it cannot be applicable to the whole population because they are affected by a selection bias.
