Handling Data (Year 6)
A pie chart represents the data in the fractions of a circle.

Handling Data (Year 6)

In Year 6 Maths, pupils use advanced skills to handle data. They work with line graphs, pie charts, and averages to interpret and compare real-world information.

Fascinating Fact:

Scientists use huge amounts of data to study climate change, tracking how temperatures rise by tiny decimal amounts.

In KS2 Maths, Year 6 pupils explore more detailed ways of recording and analysing data. They learn to calculate averages, use pie charts, and read complex graphs for comparisons.

  • Line Graph: A graph that uses points connected by lines to show changes over time.
  • Pie Chart: A circle divided into sections to show parts of a whole.
  • Average (Mean): The total of all values divided by the number of items.
What kind of data do Year 6 pupils work with?

Year 6 pupils work with more complex data, including line graphs, pie charts, and calculating averages like mean, mode, and median.

How do you calculate the mean average?

The mean average is found by adding all the numbers together and dividing by how many numbers there are.

Why is data handling important for Year 6?

Data handling is important because it helps pupils understand real-world information such as climate data, surveys, and statistics in daily life.

1 .
What is the range in a set of data?
The difference between the greatest and least
The middle value
The least value
The greatest value
If you find that 23 people have a pet dog and that only one person has a pet tortoise the range of your data is 1-23
2 .
What is the range in this set of data? Blue 230, Red 150, Yellow 348, Green 4
348 - 230
230 - 150
230 - 4
348 - 4
The highest frequency is 348 for yellow, and the lowest is 4 for green
3 .
What is the name of the most common frequency of data?
Mean
Range
Mode
Median
Mode is one method of finding an average of a set of numbers or data
4 .
Which is the mode of this data: 2, 5, 7, 2 , 7, 2, 3?
2
3
5
7
Out of the seven numbers there are three 2s, two 7s, one 5 and one 3. 2 is the most common so therefore the mode
5 .
What is the name of the chart that represents the data in the fractions of a circle?
Cake chart
Circus chart
Bar chart
Pie chart
Pie charts look a bit like pies that have been cut into slices
6 .
What fraction of the pie chart will represent Bus using this data: Train 25, Bus 50, Cycle 15, Walk 10?
12
13
110
14
The total of all data is 100 so Bus is 50 - therefore half
7 .
What is the median?
The difference between the greatest and least frequency
The middle frequency
The most common frequency
The highest frequency
Median is another method of finding an average of a set of numbers or data
8 .
Which is the median in this set of data: 2, 4, 4, 8, 10, 16?
2
4
6
8
There are two frequencies in the middle, so we add them and divide by 2
9 .
How is the mean calculated?
Add all the frequencies and divide by the number of frequencies
Add all the frequencies together
Add all the frequencies together and subtract the number of frequencies
Add all the frequencies together and divide by 2
Mean is the third method of finding an average of a set of numbers or data
10 .
What is the mean of this data: 11, 14, 17, 18, 20?
16
40
75
80
11 + 14 + 17 + 18 + 20 = 80
80 ÷ 5 = 16
