Tally Charts & Frequency Tables

Frequency is the number of times a particular value occurs in a set of data. Usually we would record the frequency of data in a frequency table.

Example :

Using the key: H = Hockey, B = Badminton, F = Football, each letter below indicates a student joining the sports club.

H H B F B H F F H B

B B H F H H F B H B

a) Construct a frequency table for the data.

b) Determine which club has the highest frequency and which club has the lowest frequency.

c) Calculate the percentage of students who joined the Hockey club.

Solution:

a) First, we tally the student count by the clubs they belong to. The total number of counts each club receives is the frequency of the number of students joining that club. We organise the data in the frequency table.

Club

Tally

Frequency

Hockey

8

Badminton

7

Football

b) From the frequency table, we can determine which club has the highest frequency and which club has the lowest frequency. Hockey is the club with the highest frequency and football is the club with the lowest frequency.

c) Percentage of students who joined the Hockey club
