- As a rule, probability sampling leads to a representative sample.
- Army rank (such as soldier, corporal, sergeant, lieutenant etcetera) is a variable with an ordinal scale.
- Cluster sampling is the least representative probability sampling design.
- The difference between an ordinal and ratio scale is that the ordinal scale has an absolute zero point.
- If a sample is subdivided into subsamples, a minimal sample size of 30 is necessary for every subsample.
- Concurrent validity is a form of construct validity.
- Cronbach’s alpha can only be used when a variable is measured through several statements or questions.
- Stratified sampling and cluster sampling are examples of probability sampling.
- A characteristic of a variable on interval level is that it has an absolute zero point.
- If a sample is subdivided into subsamples, a minimal sample size of 10 is necessary for every subsample.
- If your objective is to compose a representative sample, what kind of sampling technique would you choose?
- With which scale can we, for describing central tendency, determine the mode and the median, but not the mean?
- A disadvantage of cluster sampling is that it:
- The following scale type is:
- Julia stands on a pair of scales three times in succession. The first time she weighs 69 kilo, the second time 69 kilo, and the third time 69 kilo. Her real weight is 51 kilo. What is the matter with the scales?
