Welcome to your Maths Lesson number 4, Data Handling!
This is the fourth in a collection of four caches, each
corresponding to a sector of the current National Curriculum for
Mathematics in England. You can find each of the four ‘lesson’
caches separately to each other, you don’t need to find one to find
another – feel free to pick and choose. You will, however, need to
find all four ‘lessons’ in order to find “The Maths Exam” which is
listed as a multi-cache, if you choose to do so.
If you are aiming to complete all four to enable you to find
“The Maths Exam” then you must make a note of the number written
under the lid of each “Lesson” cache as you’ll need them during
your exam. Make sure you remember which number goes with which
cache, this is important. Don’t forget!
Getting back to the “Lesson” caches, you’ll need to do some
maths to find each cache. The questions will correspond to the
curriculum subject for that cache. You may use any resources you
need to work out the questions, and there are some suggested links
to get you going!
The four lessons are:
1.
Algebra
2.
Shape
3.
Number
4.
Data Handling
… And
here is a link to the final Exam.
So, onto the lesson!……
DATA HANDLING:
AVERAGES
In the place where you will go to
find the cache, you should see lots of trees!
I counted the number of leaves on 7
trees (in winter!) They were:
42 12 36 19 50 28 23
What is the Mean, Median and Range
of the leaves?
Mean = X
Median = Y
Range = Z
If you need a helping hand, look at
this website.
Cache Coordinates =
N53” (Z x 0.5).8(X–Y)4 (In the format of N00” 00.000)
W003” 0(X-Y).(Z-X)30 (In the format of W000” 00.000)
If you want to email the co-ords to
me first to check (especially if you are travelling far) then feel
free to do so BUT you must declare it on your log!
Some notes about the cache itself…
You’ll head towards Brimstage, Wirral. Head for the co-ords
posted at the top of the page to park. It’s fine to park on the
road, just don’t block the gate. Follow your GPS really, you can’t
go wrong. You’ll be walking for about 10mins to reach the cache.
You may want to get a map of the area if you want to go further
than the crossroads, there’s some good exploring to be done round
here. Look out for phesants! It’s best to keep dogs on a lead for
this reason – and there’s also a lot of horse riders using this
path.
