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

The frequency table for continuous variates is as follows.

Directions: On the basis of the given information answer the following questions. Also write at least one example of your own.
 Q 1: The frequency is highest for which class interval?165 - 168159 - 162168 - 171153 - 156 Q 2: How many class intervals have the lowest frequency?1243 Q 3: For a continuous variate can we have a class interval like 151 - 153, 154 - 156......yesno Q 4: If we wish to add a student with height 153 cm. to the data, the observation would lie in the class interval168 - 171none of these153 - 156150 - 153 Question 5: This question is available to subscribers only!
