Calculation Formula:
1) Pie Chart:
Percentage : v/n x 100%
Angle Size : v/n x 360
Format:
2)Frequncy Distribution
Sturge formula:
Classes : 1 + 3 log n
Class Width, W: ( Largets Value - Smallest Vallue ) / Number of Classes
Lower bound: Left side classes - o.5
Upper bound: Right Side Classes + 0.5
Histogram:
ogive:
Find Culmulative frequncy to make curve for the ogive
.........means frequncy 1 + the next and so on...
