Filling the gaps from Here-turi-kōkā and Hepetema , and checking out some of the planned activities that did not happen in previous weeks. Census at school and the PPDAC cycle were also enjoyed.

Each session students choose what we work on, we do not have time to complete ALL these tasks in class time. They are used as a selection to choose from.

Reaction Time Test for our PPDAC investigation.
Problem: Does reaction time improve with practice? We expect that it will improve.
Plan: We will each take the reaction time test three times and record the data.
Data: The data will be recorded in a google sheet shared in google classroom.
Analysis: We graphed the first and the best reaction time using box plots in order to compare the distributions. We can see the boxes overlap, but the minimum, lower quartile, median, mean, upper quartile and the maximum are all faster on the best time.
Conclusion: We conclude that reaction time does improve with practice, as our data shows the best time is not usually the first attempt.
Looking at the data a different way:
Looking at the data a different way:
The above graph helps us compare the reaction time of different aged people. There is no clear pattern, and some of the age groups only have one person in them so the data is not representative. I wonder if 12 year olds tend to have faster reaction times that 11 year olds. I would need a lot more people to take the test to discover the truth.

Mr N joined our statistical investigation - can you locate his data?

How old is he? Is he faster than the typical 12 year old at Ruapotaka school?
Was his first try his fastest? How can you tell?
