b. Median class is the class that contains the value that lies in the middle of
the data, ie (n / 2)th observation, with n / 2 = ....... = .........
In Table 2.3 the cumulative frequency column, until the ........ class has
been there are ............ observations. This means that the ................th data is
in the .......... class, which is the class interval ".......................". The median
class has a lower limit of .......... and a frequency of ...........
f c
Median : Md = L + . W
f m
Median : Md = .......... + .......... - ..... . ........ = ……..
.

c. Class that has the greatest frequency in Table 2.3
is ................, with frequency ........
Class before the mode class has a frequency of ..........,
so that d1 = .... - .....
Class after the mode class has a frequency of ............ ,
so that d2 = .... - ......
d 1
Mode : Mod = L + . W
d 1 + d 2
Mod = ……………….
