Section
C, question 6
Marjorie Henry, Contributor
By
the end of this month, all students
sitting the Caribbean Examination
Council's exams in June this year
must submit their school-based assessment
(SBA). I trust you have done a very
good study and scored high marks for
it. If you have not yet handed yours
in to your teacher, here is a quick
checklist you can use as you take
a last look at your completed study.
These are questions you must ask yourself.
1.
Is my title page neatly done with
the information required: the title
of my study, my name, the name of
my school, territory and year of examination?
2.
Does my table of contents have the
headings of the contents of the study
with the correct corresponding page
numbers?
3.
Are my location maps properly completed?
4.
Are my illustrations neatly done and
well integrated into my study?
5.
Have I listed the textbooks I used
as reference in alphabetical order
in my bibliography?
6.
Are my other sources of information
included as well?
If
you can respond to these in the affirmative,
your study is ready for submission.
If you cannot, you need to do the
necessary corrections. Of course,
the checklist is not exhaustive. The
whole idea here is for you to do a
last check of your work before it
is submitted.
I
had started to discuss the questions
that were given in Section C - Human
Systems - of the June 2009 CSEC question
paper. Question 5, the first on that
section, was discussed in the last
three lessons. In reference to your
syllabus, you would have noticed that
the following objectives were tested:-
1.
Explain the factors influencing distribution
of population and population density
in a named Caribbean country.
8.
Describe the pattern and consequences
of international migration in one
named Caribbean country within the
last 20 years.
Today,
I will begin to discuss Question 6.
Here is part (a):-
6.
(a) (An insert is provided for this
question.) Table 1 is incomplete and
presents data for tourist arrivals
(to the nearest hundred) for selected
Caribbean countries in 2006.

On
the insert provided, complete the
following:
(i)
Table 1 to show the angles, to the
nearest degree, for St Lucia, and
Trinidad and Tobago. (2 marks)
(ii)
The pie chart to show tourist arrivals
for Barbados, St Lucia, Trinidad and
Tobago. (2 marks)
In
this section of the question that
tests skills, you are being asked
to, first of all, complete a table
then use the data from the table to
complete a pie chart.There are two
approaches you can use in order to
calculate the angles for the countries
named.
Method
1: Since a circle is 360
degrees, 1 per cent equals 3.6 degrees.
Multiply the percentage of arrivals
by 3.6. For example, for St Lucia,
it would be 23.3 X 3.6 = 83.88
Method
2: Divide the number of
tourists for each country by the total
number of tourists then multiply by
360. For example, for St Lucia, it
would be 302 500 divided by 1 300
300 X 360 = 83.75
Your
answers for both territories should
be as follows:
St
Lucia - 84 degrees; Trinidad and Tobago
- 64 degrees. Remember, you are instructed
to round off the angles to the nearest
degree. Write the answers on the table
as required.

You
must next construct your pie chart.
I have already reminded you that a
circle is 360 degrees and, therefore,
it is equal to 100 per cent. The information
from the table under the column 'Percentage
of Arrivals' shows segments of the
whole. Use you protractors and sharp
pointed pencils to mark off these
segments on the given pie chart. Write
neatly, the name of the country in
each corresponding segment. Complete
your pie chart properly with a title
and a key. You may choose to write
only the percentages in each segment,
as already indicated, or you may wish
to shade each segment. Please note
that it is the percentages you must
indicate and NOT the degrees. It cannot
be overemphasised that your work must
be done neatly.
The
discussion on the question continues
in the next lesson.
