Lesson 2 – Today we ‘did’ our observation proper – we first decided what we considered boys toys to be, lile playing with cars. Then we decided that girl toys might be things like playing withdolls. We created an observation categories check list and did an event sample of children playing in a nursery. We watched the video clip a number of times to improve inter-observer reliability. It was clear than making our observation objective was very difficult!
Lesson 3 – Writing up and evaluating the observation, calculating the chi square and working out why our results were not significant even though the bar chart looked like it should be! The problem was the sample was just too small. Why do boys and girls prefer different toys written up version of the observation pack
