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.
