Sample: the first question, solved

Is a survey asking "what is your favorite pet" qualitative, discrete, or continuous?

📘 Worked solution
Qualitative - it records a category (a type of pet), not a number.

And one from the hard end

A study collects continuous data ("reaction time in seconds") from 200 people across two testing sites (80 at Site A, 120 at Site B). Site A finds 20 people react in under 0.3s; Site B finds 36 people react in under 0.3s. Which site has the higher percentage of fast reactions, and why is comparing percentages fairer than comparing the raw counts of 20 vs. 36?
