Final answer:
Salary in euros is quantitative continuous data because it results from measuring and can vary in a continuous range, including fractions and decimals.
Step-by-step explanation:
The type of data collected, which is salary (in euros), is an example of quantitative continuous data. This type of data is the result of measuring and can include a wide range of numerical values, including fractions and decimals, reflecting the precise amount of salary that people earn. Salaries can vary infinitely, as they can be expressed in terms of cents or smaller currency units, and therefore are not restricted to integer values, which distinguishes them from discrete data. In contrast, discrete data results from counting, where values take on only specific, separate numbers, such as the number of times per week something occurs or the number of books in a backpack, as highlighted in the provided examples.
For instance, if you count the number of times per week someone visits a park, you would get discrete data because the number of visits can only be whole numbers like zero, one, two, etc. Duration, on the other hand, like the amount of time spent in the park, is continuous because it can be measured to a fine degree of accuracy, such as 1.5 hours o
