CXC CSEC General Proficiency math topic:

STATISTICS

These are the specific learning objectives that CXC has set for this CSEC math topic

 CONTENT: Classification and tabulation of data; frequency distribution or table, and their representation by pie charts, bar charts, line graphs, histograms, range, frequency ploygons, interquartile and semi-interquartile range as measures of dispersion (spread); mean, median and mode as measures of central tendency; simple, experimental and theoretical probability. Grouped frequency, cumulative frequency, simple probability. SPECIFIC OBJECTIVES: The student should be able to: 1. Construct a simple frequency table for a given set of data 2. Given class size, determine class interval, boundaries and class limits for a given set of data; 3. Construct a grouped frequency table for a given set of data; 4. Draw and use pie charts, bar charts, line graphs, histograms, and frequency polygons; 5. Determine the mean, median and mode for a set of data; 6. Determine when it is most appropriate to use mean, median or mode as the average for a set of data; 7. Determine the range, interquartile and semi-interquartile ranges for a set of data; 8. Determine experimental and theoretical probabilities of simple events; 9. Apply simple statistical methods to analyze data and make appropriate inferences; 10. Use investigations to make inferences and generalizations utilizing the concepts listed above. 11. Use the mid-point of the class interval to estimate the mean of data presented in grouped frequency tables; 12. Construct a cumulative frequency table for a given set of data; 13. Determine from the cumulative frequency table, the proportion and/or percentage of the sample above or below a given value; 14. Draw and use a cumulative frequency curve (Ogive); 15. Estimate the median of a grouped set of data; 16. Analyze statistical data, commenting on the averages, the spread and the shape of the frequency distribution; 17. Use theoretical probability in chance experiments, with equally likely outcomes, to predict the expected value of a given set of outcomes.
