This week, Mr Ogilvie's maths groups used statistical investigations to find out the average score of each group in Athletics Day.
First, they were given a class's score points. They added up the data sets for each group using repeated addition and multiplication. They recorded the total scores on a google sheet. Then, they found out the averages of the class group scores using their data sets. They added up the all the group scores and divided it by the amount of classes which was 9.
In their blogpost, they explained how to add a data set and how they found the average group score for Athletics day. They recounted what they did, as well as explaining how they did it.
Mr Ogilvie's maths groups enjoyed doing a statistical investigation to find out the average group scores. They also enjoyed using repeated addition and complex multiplication to find out data sets.
