Quantitative data means numerical data which can be one of:
-a raw number
-a percentage = [the number of people per 100 in a population]%
-a rate = the number of people per 1,000 in a population
It is often associated with structured interviews, official statistics, and lab experiments
Strengths[]
Replicable, thus more reliable
Objective, so less researcher bias
Easy to make statistical comparisons and correlations
Possible to track changes over time (for longitudinal studies)
Limitations[]
Not naturalistic; puts participants in an artificial social setting
Lacks depth; doesn't explain the numbers
Difficult/impossible to quantify complicated behaviours
As a result, the validity of quantitative data is limited
