Let l be the lower class limit of a class-interval in a frequency distribution and m be the mid point of the class. Then, the upper class limit of the class is(a) m+l+m2(b) l+m+l2(c) 2m − 1(d) m − 2l

1.	Let l be the lower class limit of a class-interval in a frequency distribution and m be the mid point of the class. Then, the upper class limit of the class is(a) m+l+m2(b) l+m+l2(c) 2m − 1(d) m − 2l
Answer» Let l be the lower class limit of a class-interval in a frequency distribution and m be the mid point of the class. Then, the upper class limit of the class is (a) m+ $\frac{l + m}{2}$ (b) l+ $\frac{m + l}{2}$ (c) 2m − 1 (d) m − 2l
