Averages
The arithmetic mean is the sum of all observations divided by the number of observations. The mode is the observation that occurs most often; data can have more than one mode. The median is the middle value of the data arranged in order; if the count is even it is the average of the two middle values. The range is the largest value minus the smallest.
Graphs
A bar graph uses bars of equal width and heights proportional to the values, to compare categories. A double bar graph compares two sets of data. A pie chart shows how a whole is divided: the central angle of a sector equals the fraction of the data times 360°.
Chance and Probability
An outcome is a possible result of an experiment and an event is a set of outcomes. For equally likely outcomes, probability of an event = number of favourable outcomes / total number of outcomes. It lies between 0 (impossible) and 1 (certain), and P(not E) = 1 - P(E).
Worked Example
Find the median of 15, 12, 11, 20, 18, 25. Arrange the data: 11, 12, 15, 18, 20, 25. There are six values, so the median is the average of 15 and 18, which is 16.5.
