Answer» (i) Any character which is capable of taking several different values is called a variate. (ii) Each group into which the raw data is condensed, is called a class interval. (iii) The difference between the true upper limit and the true lower limit of a class is called its class size. (iv) The average of upper limit and lower limit of class interval is called as a class mark. (v) Each class is bounded by two figures, which are called class limits. (vi) In the exclusive form, the upper and lower limits of a class are respectively known as the true upper limit and true lower limit. (vii) The number of times an observation occurs in a class is called the frequency. (viii) The cumulative frequency corresponding to a class is the sum of all frequencies up to and including that class.

(i) Any character which is capable of taking several different values is called a variate.

(ii) Each group into which the raw data is condensed, is called a class interval.

(iii) The difference between the true upper limit and the true lower limit of a class is called its class size.

(iv) The average of upper limit and lower limit of class interval is called as a class mark.

(v) Each class is bounded by two figures, which are called class limits.

(vi) In the exclusive form, the upper and lower limits of a class are respectively known as the true upper limit and true lower limit.

(vii) The number of times an observation occurs in a class is called the frequency.

(viii) The cumulative frequency corresponding to a class is the sum of all frequencies up to and including that class.
