Kira looked through online census information to determine the average number of people living in the homes in her city. What is true about Kira’s data collection?

Kira used census information that was already collected and published online, so it is published data rather than data from her own observational study. The number of people living in each home is numerical, and an average is calculated from those numbers, making the data quantitative. Therefore, the correct choice is “Kira used published data that is quantitative.”
