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 real-world 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; 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. 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 semi-interquartile range. 9. construct a cumulative frequency table for ungrouped and grouped data; 10 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. 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 Here are our statistics tutorials to help you prepare for this section of the CXC math exam
