Qualitative: observational measures, focuses on behaviour in natural settings, small group and limited setting, describe or capture themes that emerge from the data, data are non-numerical and expressed in language and/or images. The aim of qualitative analysis is a complete detailed description. Data is in the form of words (interviews), pictures (videos), or objects (artifacts). Qualitative data is richer, time consuming, and less able. In quantitative research we classify features, count them, and construct statistical models in an attempt to explain what is observed. All aspects of the study are carefully designed before data is collected. Researcher uses tools (questionnaires or equipment) to collect data. Data is in the form of numbers and statistics. Quantitative data is more efficient, able to test. A clock is valid if it keeps (cid:272)o(cid:396)(cid:396)e(cid:272)t ti(cid:373)e(cid:859)
