Topics STATISTICS
Quartile are measures of dispersion around the median,which is a measure of central tendency.
-The median divides the days into two halves. The lower and upper quarters further subdivide the into quarters.
There are three quartile
–The Lower Quartile (Q1)
–The Median (Q2)
–The upper quartile (Q3)

Example
Consider the…[Read more]

Measures of dispersion
Measuresof dispersion show how the data set is spread around the mean or median. There are five measures of dispersion that you will study in Grade 10.
1. Range
2. Quartile
3. Inter-quartile range
4. Semu-inter-quartile range
5. Percentiles

1. RANGE;: The range of a data set is defined as the…[Read more]

FUNCTIONS
A function is a set of ordered pairs (x;y) in which there are no two ordered pairs that have the same x value.

x-value is called the INPUT VALUES or INDEPENDENT VARIABLE.
y-value is called the OUTPUT VALUES or DEPENDENT VARIABLE

The function can represented using functional and mapping notation.

Functional Notation
