​The example from the starter question is shown in the middle.

This tells us that the first two numbers where ​a score of 0. The numbers from 2 to 6 where a 1, and the numbers from 6 to 13 where a 2.

From this example we can see that the 12th number is a 2 and our median is a 2.​

​Using the Cumulative Frequency

Example from Starter Question:

23/2 = 11.5

Therefore, the 12th number in data is the median

How do we know what number is the 12th number? (Look at the Cumulative Frequency column) ​

​Divide total Frequency by 2

​Next: Calculate the Median

​*These type of questions will be on the test *

1) Draw each table into your books and complete the missing information

2) Underneath each table you must calculate the

a) ​mean

b) range

c) mode

d) median ​
