CHAPTER 2 Experimental Quantitative Approaches: Laboratory Experiments Introduction
ОглавлениеI guess that most of us can remember laboratory experiments from our school days – unless, as some do, you have blanked this out! Laboratory experiments are:
In the quantitative domain – we measure and count, we use numbers.
They are usually hypothetico‐deductive – we have a clear purpose and set of expectations in mind before we begin.
They are in the interventional domain – we introduce an experimental variable which was not there at the start.
They are prospective – we have a start point where we make our initial measurements, we have our interventions, and we have an end point when we make our final measurements.
They are best suited to answering questions like: ‘If I add/change this, will that happen?’
(None of my science teachers at school or university explained anything of the methodological science behind what we were doing – and that was a great pity. Over the years I have had to explain to undergraduate and postgraduate students the principles which underpin the ‘sciences’ of research – because most of them did not understand it either! Well, now, you do!)
