Which of the following data sets is suitable to calculate how many hospitals there are in a city? Is it (A) mass population or (B) samples?

When deciding which type of data set to choose, we need to consider any constraints. These include time and money, but they also include what we are trying to find out from our question. In this question, we need to calculate the number of hospitals in a city. This means that we want an exact answer. As a result, taking a sample would not be beneficial, as there could be more hospitals in some areas of the city than in others. In order to calculate how many hospitals are in a city, we would need to count each individual hospital. This means that we need to use the whole population. The correct answer is therefore option (A). The data set that is most suitable is mass population.
