TAUPO TROUT INFERENCE BIVARIATE YEARS 9 TO 13
There is no charge for this data. It was collected during the International Lake Taupo Trout Fishing Competition 1993 to 2011. The Department of Conservation Fishing Rangers measured and recorded all the data supplied by the hundreds of anglers who enjoyed the fishing competition. A lot of fun was had by all.

Main document - Lake Taupo Trout description, more contextual info. Some good Y9 and 10 ideas and sample assessment ideas for inference form Year 11 to 13.

All trout data has been formated as .csv files.

Learning and Teaching Ideas.
1. I suggest you develop this context in Year 9 and continue to use it in increasingly sophisticated ways for learning and for assessment to Year 13. As explained in the Main document there are ample opportunites to build mathematics and statistical concepts.
2. Used with iNZIGHT the data can be used to model sample variation and bootstrapping.
3. One of the great resources to make is the box with a 1000 or so fish cut up and floating around. I decorate the box with pictures of the lake and have students sample and make dot plots and box and whisker plots.
4. WWW Shape, Moddle 50%, Spread and Oddities. The WWW satnd for What do I see? Where is it? and What does it mean? This is a great literacy strategy to help students write sensible statements upon which to base conclusions. PPDAC rules of course, The Eyes Have It!

Census at School has this info as well as people have developed ideas. http://new.censusatschool.org.nz/search/?q=trout

And...Go fishing on the big lake. There are 62 cubic km of water there and you can drink it. Teach a kid to fly fish, spin fish or just look at them.
