Cumulative Frequency
Y-axis
Cumulative relative frequency graph
Why use Orgive?
To represent how many values are below a certain upper class boundary
The
horizontal
scale identifies
upper-class boundaries
Vertical
scale identifies either the
cumulative frequency/cumulative relative frequency
Histogram
The bar always touch
The lowest and highest value that can fit in a class are called the lower and upper class limit
The Centre of the class is called the Midpoint, (Lower class limit + Upper class limit)/2
Polygon: Line Graph
The width of the bars represent a quantitative value
Axis-Y - frequency

Uniform/Rectangular Histogram
Histogram skewed to left
