Many elements in the domain are linked to the same element in the range.
On a graph: If you move a vertical line across the graph, the line will cut the graph only once, but if you move a horizontal line across the graph, it will cut the graph more than once.
|maximum||The biggest value.|
One of the measures of central tendency, calculated by dividing the sum of all the data values by the number of data values.
|measures of central tendency||The mean, median and mode. These are averages which use one value to summarise a set of data.|
|measures of dispersion||These values tell us how spread out the data is (e.g. range, inter-quartile range and standard deviation).|
This is a measure of central tendency. The median is the middle value when the data is arranged from smallest to biggest. If there are two middle values, the median is the average of these two values.
The line joining the midpoints of two sides of a triangle is parallel to the third side and is equal to half this third side.
|minimum||The smallest value.|
A number which contains a whole number and a proper fraction.
|modal class||The class interval with the highest frequency in grouped data.|
|mode||A measure of central tendency. This is the data value which appears the most often.|
|monomial||An algebraic expression with only one term.|
|mutually exclusive (probability)||
Events which have no common outcomes.
e.g. even and odd numbers are mutually exclusive because numbers cannot be even and odd at the same time
If A and B are mutually exclusive, then P(A and B) = 0.
