Research Methods
  1. Sample
    1. Target population - group interested in studying
      1. Sample - the participants
        1. if the sample represents the target population then it is generalisable
        2. Data
          1. Types of data
            1. Quantitative - numbers
              1. Qualitative - words
              2. Levels of data
                1. Nominal - Tally/total number of times something happens
                  1. Ordinal - Rank order, from smallest to largest
                    1. Interval - Precise measurement (universal)
                    2. Primary - collected by researcher
                      1. Secondary - gathered by someone else
                      2. Reliability
                        1. How consistent a measuring device is
                          1. Internal - can you replicate the study?
                            1. Split-half method - compare results of one half with the other. if positive correlation its is assumed to be consistent
                              1. Inter-rater reliability - if different observers get the same results
                              2. External - have the participants got a consistent result?
                                1. Test-retest method - compare results taken on two different occasions
                              3. Validity
                                1. How accurate a study is
                                  1. Internal - Does it measure what its meant to measure?
                                    1. Face validity - does it measure what its supposed too
                                      1. Construct validity - is the measuring device appropriate to the concept
                                        1. Concurrent validity - comparing it with a well established test
                                          1. Criterion validity - how well it predicts future performances
                                          2. External - can the results be generalised to more people?
                                            1. Population validity - can the results be generalised to the wider population
                                              1. Ecological validity - resembles what will happen in everyday life
