Mean, Median and Mode


Posted by Miss Crowther | Posted in Numeracy | Posted on February 20, 2014

We are learning about data and how to explain information.  This blog post was written during our reflection and summary of today’s numeracy session.

Learning Intention: 

To understand the terms mean, median and mode and calculate them using a set of data.

Success Criteria:

#1 Record data in a table

#2 Identify mean, median and mode for a set of data

#3 Explain how to find mean, median and mode

We worked with a partner to find out about the seven day weather forecast for a city.  The city could be anywhere in the world.  We discovered that in some parts of the world it is still Wednesday, even though it is Thursday here.

We collected our data from a website

We collected our data from a website


We recorded our data in a table to meet success criteria #1.  We calculated the mean, median and mode to meet success criteria #2.



This blog post is to prove that we can explain how to find the mean, median and mode from a set of data.  If we can explain it clearly and accurately we will meet success criteria #3.


To find the mean you add all the numbers in the data set together and in our case, divide it by the number of days.

5 + 6 + 5 + 6 + 8 + 7 + 6 = 43

43 divided by 7 = 6.1

Paris’ mean minimum temperature for the week ahead is 6.1C.  Brrrrr!


To find the median you have to write all the numbers in the data set from lowest to highest, or ascending order.  The middle number is the median.

20, 21, 21, 21, 26, 27, 27

LA’s median maximum temperature for the week ahead is 21C.


Mode is another word for most.  It is the number that occurs most frequently in the set of data.  To help work it out, put the data in ascending order.

1, 1, 3, 8, 8, 10 11,

New York’s maximum mode is 1 and 8 because they are the temperatures that are forecast to occur most frequently in the next seven days.

Hobart’s minimum temperature mode is 12 because it is forecast to happen three times in the coming week.

8, 9, 11, 11, 12, 12, 12


Have we explained what mean, median and mode mean and how to calculate them?


Do you think we have been successful learners today?


When have you worked with data?

Dear 5/6 @UPPS,
Well done for a super clear explanation! Do you have any tricks for remembering which is which, because that can be tricky, can’t it? I like the idea of using weather statistics, but can you think of anything else you could find the mean, median and mode of?
Mrs Monaghan

I think you have done an excellent job explaining the three concepts. I knew about the mean and median but today you taught me about the mode. Thank you!!
