General

I have not taught Statistics since the new standards came in, so this material is for the old ones. Mostly it still applies, but there are some differences.

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

Probability Distributions

Practice 1        Practice 2        Practice 3        pdf files

Each is one page of questions, plus one of worked answers. They are effectively practice exams. You should try to complete them in 30-40 minutes each. They do not include rectangular or triangular distributions, which were added in the new standard.

Practice 1        Practice 2        Practice 3

Practice 4        Practice 5        Practice 6        pdf files

Each is one page of questions, plus one of worked answers. Each represents the Achieved and lower Merit of an exam. You should try to complete them in 30 minutes.


Harder 1        Harder 2        Harder 3        pdf files

Each is one page of questions, plus two of worked answers. Each represents the harder questions of an exam. Ignore the combinatorics questions (although the non-theory ones can usually be done by trees or other similar methods) unless you are doing Scholarship.
