Research that collects non-numerical data, such as words, images or observed behaviour, and interprets it to understand meanings and experiences in depth.
Numerical data, such as scores, counts, times or ratings, that can be summarised with descriptive statistics and analysed with inferential statistics.
Research that collects numerical data and analyses it statistically, usually to test hypotheses about relationships between variables.
A study that compares conditions without random allocation of participants, often because the groups already exist (such as cultures, sexes or age groups), so cause and effect cannot be firmly established.
