Introduction
This module introduces you to STEP 2 questions which involve Statistics.
This STEP 2 module consists of 6 STEP questions, some topic notes and useful formulae, a "hints" sheet and a "solutions" booklet.
STEP questions are challenging, so don't worry if you get stuck. These STEP 2 modules assume that you have already begun to develop your problem-solving skills and approach to STEP questions by working on the Foundation modules.
About this assignment
STEP Statistics questions usually focus on probability rather than hypothesis testing and data analysis. You may find that some questions can be answered with just GCSE probability. One of the questions in this assignment actually requires you to look up a value in a table - such as can be found in the (old) STEP formulae book which can be downloaded from this page. One of these questions is a STEP I question from when the Poisson distribution was on the STEP I specification (before 2019).
Hints, support and self evaluation
The “Hints" file gives suggestions and some starting points on how you can tackle the questions. The "Solutions" file leads you through one possible solution, but some steps will be missing and you will still need to work through the question yourself.
