IMHO, calculating an average is something every teacher should have to do many times throughout their career (at the very least for calculating how well individual students performed on a test relative to their peers).
Calculating an average is the statistical equivalent of 2 + 2. Who could respect a teacher who had to look up the algorithm for 2 + 2 every time they were asked to compute it?
- Retric 12y agoI would hope most teachers stopped calculating averages by hand a long time ago.
- swalsh 12y agoYou still need to know the algorithm though to understand it's limitations.
- cbgb 12y agoSimilar to another comment, how can you evaluate the correctness of the computed value if you don't know how the computation is done?
- j2kun 12y agoBut understanding what an average represents is obviously important.
