The masses of a group of students from Kilimani secondary school were recorded as shown in the following table:
Mass in kilograms | 31 - 40 | 41 - 50 | 51 - 60 | 61 - 70 | 71 - 80 |
Frequency | 2 | 5 | 3 | 9 | 1 |
(i)How many students are there in the group?
(ii)State the class interval that has the largest number of students.
(iii)Prepare a table showing the class boundaries and the corresponding cumulative frequencies.

60 | 64 | 63 | 67 | 66 | 68 | 59 | 58 | 59 | 60 |
64 | 66 | 65 | 60 | 73 | 70 | 63 | 69 | 70 | 60 |
66 | 70 | 74 | 69 | 63 | 69 | 59 | 65 | 64 | 65 |
73 | 61 | 62 | 64 | 61 | 61 | 62 | 63 | 58 | 73 |
From the data given, construct a frequency distribution table taking equal class intervals 57 - 61, 62 -66, 67 - 71, … and determine the class interval with the highest frequency.

Marks% | 40 | 45 | 50 | 55 | 60 | 65 | 70 |
Number of students | 6 | 8 | M | 5 | 9 | 4 | 3 |
From the table, determine the value of M if the total number of students was 48, hence calculate the percentage of the students who scored at least 55 marks.
View AnsThe age of students selected o participate in a debate competition were recorded as follows
13 | 15 | 17 | 16 | 15 |
14 | 16 | 18 | 17 | 16 |
15 | 14 | 13 | 16 | 14 |
17 | 15 | 16 | 15 | 16 |
(i)Prepare a frequency table showing the ages of students and their corresponding frequencies
(ii)Draw a frequency polygon representing the given information
View AnsThe following table shows marks for a Form Two History monthly test:
Marks in % | 25 | 35 | 40 | 50 | 60 | 65 | 70 | 75 | 80 |
No. of studs. | 2 | 3 | 5 | 7 | 11 | 7 | 4 | 2 | 1 |
(a)What is the lowest mark?
(b)What is he highest mark?
(c)Which mark is scored by the greatest number of students?
(d)If 60% is the pass mark in the test, how many students failed?
(e) How many students are in Form Two class
View AnsThe marks of 61 students are represented int he following table:
Mark in % | 30 | 35 | 45 | 50 | 60 | 75 | 80 | 85 | 90 |
Number of students | 3 | 5 | 7 | 10 | 18 | 9 | 4 | 3 | 2 |
From the table answer the following questions:
(i)Which mark was scored by few students?
(ii)What was the highest mark?
(iii)If 50% was the pass mark in the examination, how many students passed the examination?
(iv)Which mark was scored by many students?
