A researcher determines that 42.7% of all downtown office buildings have ventilation probles. Is this census data or sample data?

If all the buildings are included, it is census data.

To determine whether the given information represents census data or sample data, we need to understand the difference between the two.

Census Data:
Census data refers to information collected from the entire population or all members of a particular group. It aims to provide a complete and accurate representation of the entire population. Conducting a census involves collecting data from everyone or every element in the target population.

Sample Data:
Sample data refers to information collected from a subset or a smaller group of individuals or elements from the target population. The goal is to use this sample to make inferences or draw conclusions about the entire population.

In the given scenario, the researcher determined that 42.7% of all downtown office buildings have ventilation problems. Without further clarification, we cannot definitively say whether this is census data or sample data.

If the researcher collected data from every single downtown office building in the area, then it would be considered census data because it represents the entire population of downtown office buildings.

On the other hand, if the researcher collected data from a smaller subset or sample of downtown office buildings and then generalized the findings to the entire population, it would be considered sample data.

Therefore, without more information about the data collection method, we cannot determine whether the given information represents census data or sample data.

Based on the given information, it is not explicitly stated whether the researcher obtained this data from a census or a sample. Census data refers to collecting information from every member of the population, whereas sample data refers to collecting data from a subset of the population.

If the researcher collected data from all downtown office buildings, then it would be considered census data. However, if the researcher only collected data from a subset of downtown office buildings, then it would be considered sample data. Without further information, it is difficult to determine whether the data is census data or sample data.
