Which of the following data sets
would be suitable to check the education level in the poor villages in Africa? Is it (A) mass population or (B)
When deciding which data set to
use, we need to factor in any constraints. Two of the biggest constraints when
collecting data are time and money. In this particular question, we
need to ask ourselves whether it is possible to check the education level of every
child in the poor villages in Africa. If this was a sensible method, we
could use the mass population. However, as it is not realistic to
visit every village in Africa, we need to choose samples.
We could choose a sample of
different villages and then a sample of children from each of the villages
chosen. This would be the most suitable way
to check the education level in the villages in Africa.
