After some matches were played, most of the information in the
table containing the results of the games was accidentally deleted.
What was the score in each match played?
Using the 8 dominoes make a square where each of the columns and
rows adds up to 8
There are exactly 3 ways to add 4 odd numbers to get 10. Find all
the ways of adding 8 odd numbers to get 20. To be sure of getting
all the solutions you will need to be systematic. What about a
total of 15 with 6 odd numbers?
Working in groups to analyse separate sections of the text may
be a useful whole class activity even if pupils then work in
smaller groups to analyse the data.
By sorting the letters by time values you can get an
approximation to Morse's findings.
A simple frequency count would give a first clue to differences.
Are there any letters whose frequency is significantly different
when the two distributions are matched?
Using the new code and translating is there a "significant"
difference in the times the messages would take?
By weighting letter time values according to their frequency it
should be possible to see whether the average time taken to send a
message using each of the two systems, or between systems generated
by groups of pupils, differ.
