STATISTICS
-MEASURE OF CENTRAL TENDENCY
There are three measures of central tendency :
1. Mean (Average )
2. Median (Middle value of data
set.)
3. Mode (Most frequent value in a
data set.)
MEAN : The mean is the sum of data values in the data set divided by the number of data points in data set.
MEDIAN : The median is middle value of an…[Read more]

The trigonometric ratios are defined using rights angled triangles.Using these ratios, you can calculate the size of any angle and side of a right angled triangle. For triangles that do not have a right angles,we can derive rules that help us solve unknown angle or sides.These triangles may be drawn in either horizontal plane or the vertical…[Read more]

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]
