Which research design allows researchers to infer causation, rather than just correlation?

Using a widely-used subjective quantitative measure of mood like the Brief Mood Introspection Scale (BMIS) is likely to have:

The extent to which results can be generalised to 'real-life' applications is known as:

A researcher completes a survey and wants to know which age group made up the largest proportion of respondents.

Which measure of central tendency would be best?

A normal distribution is evident in a data set, and the researcher wants to know what the average response was.

Which measure of central tendency would be best?

A data set has a significant outlier.

Which measure of central tendency would be best?

A small standard deviation means that the data set has:

A small data set is mostly likely to impact:

Selecting a sample at random from a population refers to:
