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. |
| 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 |
