In the class intervals $10-20, 20-30, 20$ is taken in

In a frequency distribution, the mid-value of a class is $15$ and the class intervals is $4$. The lower limit of the class is

The mid-value of a class interval is $42$. If the class size is $10$, then the upper and lower limits of the class respectively are:

The number of times a particular item occurs in a given data is called its

The width of each of nine classes in a frequency distribution is $2.5$ and the lower class boundary of the lowest class $10.6$. Then the upper class boundary of the highest class is

The following marks were obtained by the students in a test: $81, 72, 90, 90, 86, 85, 92, 70, 71, 83, 89, 95, 85, 79, 62$. The range of the marks is

Tally's are usually marked in a bunch of

Let $\mathrm{l}$ be the lower class limit of a class-interval in frequency distribution and $\mathrm{m}$ be the midpoint of the class. Then, the upper-class limit of the class is
