General

I am updating the material here as I go, because I haven't been teaching Statistics since the standards changed. It will take a while to get all the material aligned properly. Please bear with me.

I would appreciate any corrections if I have made any errors: markp @ stjohns-hamilton.school.nz (no gaps).
 

Equations

This topic is largely the same as the old standard, although it used to be an external.

Practice 1        Practice 2        Practice 3        pdf files

Practice 4        Practice 5        Practice 6

Worksheets with a couple of exercises at each level.
 

This is quite a good explanation of the process for solving 3 x 3 equations by hand from http://www.slideshare.net


 
Extension work        pdf file
 

Linear Programming

This topic is largely the same as the old standard, although it used to be an external.

Practice 1        Practice 2        Practice 3        pdf files

Practice 4

Worksheets, with an Achieved example first, followed by a Merit/Excellence example. The later ones are harder.
 

Bivariate Data

This topic has changed a great deal, most especially in terms of the types of data given.

Notes and Worksheet        Completed Worksheet        pdf files

The scope of the old unit, with spaces for questions. The second sheet gives the answers.

The original for the worksheet can be found at http://www.stat.auckland.ac.nz/~teachers/2003/regression.php along with other resources.


Crackers: Exercise and Answer        Fertility Exercise        Bond Yields Exercise        pdf files

Data for Practice        zip file

Questions and data to practice on, one with model answers.


NZQA Official Exemplar A        NZQA Official Exemplar B

Examples of student work given by NZQA which show the boundary between the various grades. Note how answers alone do not achieve a grade unless backed up with analysis.
 

Time Series

Time Series Notes        zip file

Three sets of PowerPoint slides. The first goes through the process of analysing the data in Excel. The next two look at some extension areas.

 
Channel Ferries        Guest Numbers        pdf files

"Channel Ferries" is a model answer with notes about each component. "Guest Numbers" is also a model answer, showing a different way of structuring the report, but with no notes.

Examples of student work given by NZQA which show the boundary between the various grades. Note how answers alone do not achieve a grade unless backed up with analysis.

These tend to be on the short side and I would suggest more analysis and different graphs for the different parts, rather than combining all information onto the same (very busy) graph.
