2003 Newsletter 02
Welcome to the latest 10ticks newsletter. There's even more to do on the site!!
Code Breakers
There is a brilliant new page in the Student Area called Code Breakers. Here we
have many different ways of setting up codes and e-mailing them to friends.
Your friend will have to break the code to be able to read your message. Try
it!
What was the primary tool to break codes? Frequency Analysis! This
section has two important analysis tools, frequency analysis of letters in a
text and frequency analysis of the number of letters per word in a text.
This will be of great benefit to you if you are attempting Statistics
Coursework. Find any text on the internet and copy and paste into the box. We
have set it up so you can print the plain text and a graph of the analysis for
coursework records. This should save you a huge amount of time changing the raw
data into an ordered set of data ready for further detailed analysis.
Here are some ideas for using this tool with coursework.
Scrabble – is the scoring system fair?
Computer Keyboard – are the keys laid out in the correct position?
Use the Times website and the Sun website. Copy and paste articles from each
and complete both sets of analyses. What do you notice?
Do different foreign languages use letters differently to English?
Does ‘Olde English’ differ from modern day English?

Help Section
The level 5 Helps in the Student area are almost complete. Have you tried one?
Login and then attempt the questions from the Help. You can view all your
results in your User area. These results in the User area can help you asses
how good you are and work out a programme to help you improve. Simply work on
the helps over a period of time and then by looking at your percentage scores
find your weakest topics and spend time concentrating on these.
