We have enjoyed our maths unit on statistics. We collected some very interesting data and graphed it using PowerPoint. Today we discussed our findings:
We found that, although we should all have the same results, that this was not the case. Out data was not RELIABLE! We thought this was probably because some students had not OBSERVED the features themselves, but relied on a verbal response from their peers. In addition, there was clearly a difference of opinion about what some features actually looked like! It seems that our criteria for what was a ’straight thumb’ and a ‘hitchhikers thumb’ were not clear enough! This is good learning for next term when we do our science fair projects.
However, despite the inconsistencies, the overall patterns show clearly which are the dominant features and which are the non dominant (recessive). It will be interesting to compare the adult data and see if this is the same!
