ADDITIONAL MATHEMATICS PROJEK FOR FORM 5 2012

ADDITIONAL MATHEMATICS PROJEK FOR FORM 5 2012

Vision 2020 aims to produce a balanced human capital in terms of physical, emotional, spiritual and intellectual in accordance with the National Education Philosophy. In order to expand the intellectual aspect, every individual should have the ability to analyze data.

The picture above shows students in a secondary school having their final year examination. The School Examination secretary will collect the marks for each subjects to determine the average grade of the subjects, the average grade school and which will give the picture of the performance of the school.

             Data representation reflects the general characteristics of data that allows us to compare and thus predict and plan for the future.

PART 1:

1.      List the importance of data analysis in daily life.

2.      Specify the types of Measure of Central Tendency and of Measure of Dispersion.

PART 2:

1.                  Get the March Additional Mathematics test scores for your class. Attach the scores sheet.

2.                  Construct a frequency table as in Table 1 which contains at least five class intervals. Choose a suitable class size.

Marks	Tally	Frequency

Table 1

.

a)         From Table 1, find

(i)                 the mean,

(ii)                the mode,

(iii)              the median using two methods.

b)      Based on your findings from (a) above, state the appropriate measure of central tendency to reflect the performance of your class in Additional Mathematics. Explain why.

PART 3:

Measure of Dispersion is a measurement to determine how far the values of data in a set of datais spread out from its average value.

Based on the data from Table 1,

a)      using two methods, find

(i)                 the  interquartile  range

(ii)               the standard deviation

b)      Explain the advantages of using standard deviation compared to interquartile range to describe the data.

PART 4:

a.       If your teacher wants to make adjustments by adding 3 marks for each student in your class for their commitment and discipline shown, find the new value of mean, mode, median, class interval, interquartile range and standard deviation. Check your answers with other methods.

b.      In April 2012, a new student has enrolled in your class. The student has scored 97% in the Additional Mathematics March Test in his/her former school. If the student scores were taken into account in the analysis of your school March Test , state the effect of  the presence of this student to the mean, mode, median, interquartile range and standard deviation.
