Introduction to Statistics

In statistics we are learning about median, mode, range, Q1, Q3, IGR, lowest, highest and average. We have a test at the end of extended stay on statistics.

The 3.4km run
we run along the track, along the foreshore at Pt. Turton from wambana to the sacred rock and return.
