A questionnaire asks people to rate their stress from 1 to 10 and then to describe what makes them stressed. What type of data does each part produce?

The rating produces quantitative data. The description produces qualitative data.

What is primary data?

Primary data is collected first-hand by the researcher for the current study, such as scores from an experiment the researcher runs.

What is secondary data?

Secondary data has already been collected by someone else for a different purpose. Examples include government statistics and published research findings.

Ten participants recalled these numbers of words: 12, 15, 9, 14, 11, 13, 10, 16, 12, 18. Calculate the mean.

The mean is 13 words. The calculation is 130 ÷ 10 = 13.
