Q.- The distances (in km) covered by 24 cars in 2 hours are given below :
125, 140, 128, 108, 96, 149, 136, 112, 84, 123, 130, 120, 103, 89, 65, 103, 145, 97, 102, 87, 67, 78, 98, 126
Represent them as a cumulative frequency table using 60 as the lower limit of the first group and all the classes having the class size of 15.
 
Sol. We have, Class size = 15
Maximum distance covered = 149 km.
Minimum distance covered = 65 km.
∴ Range = (149 – 65) km = 84 km

Q.- Find the unknown entries (a,b,c,d,e,f,g) from the following frequency distribution of heights of 50 students in a class :

statistics notes 11

Sol. Since the given frequency distribution is the frequency distribution of heights of 50 students. Therefore,
g = 50.
From the table, we have
a = 12, b + 12 = 25, 12 + b + 10 = c,
12 + b + 10 + d = 43,
12 + b + 10 + d + e = 48 and
12 + b + 10 + d + e + 2 = f
 
Now, b + 12 = 25
=> b = 13
12 + b + 10 = c 
=>12 + 13 + 10 = c [b = 13]
=> c = 35
12 + b + 10 + d = 43 
=> 12 + 13 + 10 + d = 43 [ b = 13]
=> d = 8
12 + b + 10 + d + e = 48 
=> 12 + 13 + 10 + 8 + e = 48   [ b = 13, d = 8]
=> e = 5
and, 12 + b + 10 + d + e + 2 = f
=> 12 + 13 + 10 + 8 + 5 + 2 = f
=> f = 50.
Hence, a = 12, b = 13, c = 35, d = 8,
e = 5, f = 50 and g = 50.
 
Q.- The marks out of 10 obtained by 32 students
are : 2, 4, 3, 1, 5, 4, 3, 8, 9, 7, 8, 5, 4, 3,6, 7, 4, 7, 9, 8, 6, 4, 2, 1, 0, 0, 2, 6, 7, 8, 6, 1.
Array the data and form the frequency distribution
 
Sol. An array of the given data is prepared by arranging the scores in ascending order as follows :
0, 0, 1, 1, 1, 2, 2, 2, 3,3,3, 4,4,4,4,4,
5,5, 6,6,6,6, 7,7,7,7, 8,8,8,8, 9,9.
Frequency distribution of the marks is shown below

Q.- Prepare a discrete frequency distribution from the data given below, showing the weights in kg of 30 students of class VI.
39, 38, 42, 41, 39, 38, 39, 42, 41, 39, 38, 38 41, 40, 41, 42, 41, 39, 40, 38, 42, 43, 45, 43, 39, 38, 41, 40, 42, 39.
 
Sol. The discrete frequency distribution table for the weight (in kg) of 30 students is shown below.
