CXC General Proficiency Math Topic:   STATISTICS (2010)



On completion of this section, students should:

1. appreciate the advantages and disadvantages of the various ways of        presenting and representing data;

2. appreciate the necessity for taking precautions in collecting, analyzing        and interpreting statistical data and making inferences;

3. demonstrate the ability to use concepts in statisitics and probability to      describe, model and solve real-world problems.



Students should be able to:


1. differentiate between types of data;

Discrete and continuous variables. Ungrouped and grouped data.



construct a frequency table for a given set of data;


Ungrouped and grouped data.


determine class features for a given set of data;


class interval, class boundaries, class limits, class midpoint, class width.


construct statistical diagrams;


Pie-charts, bar charts, line graphs, histograms and frequency polygons.


5. interpret statistical diagrams,

Pie-charts, bar charts, line graphs, histograms and frequency polygons.


6. determine measures of central tendency for raw, ungrouped and grouped data;

Mean, median and mode.



determine when it is most appropriate to use the mean, median and mode as the average for a set of data;


Mean, median and mode as measures of central tendency.


detemine the measures of dispersion (spread) for raw, ungrouped and grouped data;

Range, interquartile range and semi-interquartile range.



construct a cumulative frequency table for ungrouped and grouped data;



draw cumulative frequency curve (Ogive);


Appropriate scale for axes.
class boundaries as domain.

11 use statistical diagrams; Mean, mode, median, quartiles range, interquartile range, semi-interquartile range.

determine the proportion or percentage of the sample above or below a given value from raw data, table or cumulative frequency curve;



identify the sample space for sample experiment;


Set of all possible outcomes.

determine experimental and theoretical probabilities of events;



make inference(s) from statistics.


Raw data, tables, diagrams
