Answer
(i) A quantity which can vary from one individual to another is called a variable.
(ii) Sizes of shoes are distinct variables.
(iii) Daily temperature is continuous variable.
(iv) The range of the data 7, 13, 6, 25, 18, 20, 16 is (25-6) = 19.
Range of the data is the difference between the highest and the lowest values.
(v) In the class interval 35 - 46; the lower limit is 35 and upper limit is 46.
(vi) The class mark of class interval 22 - 29 is 25.5.
