Continuous variate
A variable is said to be continuous if it takes any value in an interval. For eg: i)weight of a person in a group. ii)Height of a person.
Classification of continuous data
The data below gives the height (in cm) of 30 students in a class
 162.2 167.4 161.6 159.2 158 159.9 158.2 158.4 160.2 162.8 162.5 163.7 161.2 159.2 158.9 159.2 154.2 150.3 151.2 154.3 150.4 152.3 157.2 168.4 163.4 167.5 168.3 159.2 154.2 164.5
