CXC math topic: STATISTICS (2010)
CXC General Proficiency Math Topic: STATISTICS (2010) 

GENERAL OBJECTIVES 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 realworld problems. 

SPECIFIC OBJECTIVES: Students should be able to: 
CONTENT  
1.  differentiate between types of data; 
Discrete and continuous variables. Ungrouped and grouped data. 
2. 
construct a frequency table for a given set of data; 
Ungrouped and grouped data. 
3. 
determine class features for a given set of data; 
class interval, class boundaries, class limits, class midpoint, class width. 
4. 
construct statistical diagrams; 
Piecharts, bar charts, line graphs, histograms and frequency polygons. 
5.  interpret statistical diagrams, 
Piecharts, bar charts, line graphs, histograms and frequency polygons. 
6.  determine measures of central tendency for raw, ungrouped and grouped data; 
Mean, median and mode. 
7. 
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. 
8. 
detemine the measures of dispersion (spread) for raw, ungrouped and grouped data; 
Range, interquartile range and semiinterquartile range. 
9. 
construct a cumulative frequency table for ungrouped and grouped data; 

10 
draw cumulative frequency curve (Ogive); 
Appropriate scale for axes. 
11  use statistical diagrams;  Mean, mode, median, quartiles range, interquartile range, semiinterquartile range. 
12 
determine the proportion or percentage of the sample above or below a given value from raw data, table or cumulative frequency curve; 

13 
identify the sample space for sample experiment; 
Set of all possible outcomes. 
14 
determine experimental and theoretical probabilities of events; 

15 
make inference(s) from statistics. 
Raw data, tables, diagrams
