  • 11.  Knowledge: Information about or awareness of something, an issue, a fact that you have gained through learning or experience. (Longman Dictionary) Information: Facts or details that tell you something about a situation, person, events etc. (Longman Dictionary) Research Methods- Thinking about research & nature of research 11

Research Methods- Thinking about research & nature of research 23
  • 24. 1. Quantitative Research  Generates statistics through the use of large scale survey methods, questionnaire or structures interviews.  Words like: ▪ how many? ▪ How often? ▪ test, ▪ verify, are used. Research Methods- Thinking about research & nature of research 24
  • 25.  Based on measurement – applicable where quantitative measurements can be applied. Knowledge of statistical methods helps us qualify our conclusions-attach scientific probabilities (levels of significance)- and provides a basis for accepting or rejecting hypotheses.

Research Methods- Thinking about research & nature of research 31
  • 32.  Key aspects to research quality:  Reliability- or dependability (replicability) ▪ Results may/ can be replicated by other researchers using the same methods? How? ▪ (e.g. all data is included, & no data is lost) Research Methods- Thinking about research & nature of research 32
  • 33.  Key aspects to research quality:  Validity: Do the methods & tools truly measure what they are intended to measure? ▪ Internal validity: Are the data that I’m gathering relevant to my research question? ▪ I.e. will they help me to answer my research question or test my hypothesis? ▪ External validity: can results of my research be generalized to the wider population? Research Methods- Thinking about research & nature of research 33
  • 34.  Quality criteria in Research (Becker et al 2006):  Accessible to appropriate audience.  Clearly addresses the research question.  Transparency in data collection & analysis.  A clear statement of how the research process was conducted.  The research makes a contribution to knowledge.  More… Research Methods- Thinking about research & nature of research 34
