Lesson 30 How do I handle the data?
Lesson plan
Piagetian Level | ||||
---|---|---|---|---|
3 B Mature Formal |
‘the girls’ science levels are more closely related to their English than the boys’ — maybe we ought to look at the ratios of confirming to disconfirming cases' | |||
‘if a girl gets level 4 in English, then her science level will be between 2 and 5, but the boys’ range 7 is from 1 to 7’ | ||||
3A Early Formal |
‘if you look at the Grades A to C, then they do much the same: boys do worse in lower grades’ |
‘to test the idea that the reaction rate is proportional to concentration you have to plot t/time as a measure of speed to see it the speed doubles’ | Choice of correlation diagram to compare results |
|
‘Yes, you can see that the girls do better than the boys’ | 'looking at the graph, it seems that at each temperature, the one reaction is going about twice as fast’ | |||
