In this section we look at collecting and presenting data. We also look at extracting data from tables and timetables.
The table gives the distances, in miles, between some towns and cities. Use this table to answer the questions below.
How far is it from Hull to Nottingham?
Andy drives from Leicester to Lincoln and then on from Lincoln to Doncaster. How far does he drive altogether?
From the table,  Leicester to Lincoln is 51 miles 
and  Lincoln to Doncaster is 39 miles. 
Total distance  = 51 + 39 
= 90 miles 
Ian drives from Hull to Sheffield and then back to Hull. How many miles, in total, does he drive?
Total distance  = 61 × 2 
= 122 miles 
Use the following timetable to answer the questions below.
Alan catches the 2017 train at Cuffley. When does he arrive at Hornsey?
Julie arrives at Hornsey at 2212. When did she leave Palmers Green?
A class of pupils take a test. Their scores are listed below:
17  23  46  31  17  19  26  31  42  5 
21  32  36  37  32  38  41  40  19  12 
7  48  29  39  42  38  41  32  36  35 
Draw a stem and leaf diagram for this data.
In the following stem and leaf plot the data has not been put into order;
Stem  Leaf  

0  5  7  
1  7  7  9  9  2  
2  3  6  1  9

4  6  2  1  0  8  2  1 
The leaves can now be ordered as shown to produce the final diagram:

A student records the temperature in a greenhouse every 4 hours during 1 day. The results are listed below:

Draw a line graph and use it to estimate the temperature at 1000 and 1400.
15 °C at 1000  
and  23 °C at 1400. 
Throughout a 4week period a class recorded the number of children absent each day. Their results are listed below:
1  0  4  3  1  2  1  3  4  5 
7  1  2  2  3  3  1  3  1  0 
Collate this data using a tally chart and draw a vertical line graph to illustrate the data.

These pie charts show some information about the ages of people in Greece and in Ireland. There are about 10 million people in Greece, and there are about 3.5 million people in Ireland.
Roughly what percentage of people in Greece are aged 40  59 ?
The angle for 4059 is about 90°; 
the fraction of the total is  =  , or 25%. 
There are about 10 million people in Greece. Use your percentage from part (a) to work out roughly how many people in Greece are aged 40  59.
25% of Greece's population =  × 10 million = 2.5 million. 
Dewi says that these charts show that there are more people under 15 in Ireland than in Greece.
Dewi is wrong. Explain why the charts do not show this.
Ireland : 
 
Greece : 

There are about 60 million people in the UK. The table shows roughly what percentage of people in the UK are of different ages.

Copy and complete the pie chart below to show the information in the table. Label each section of your pie chart clearly with the ages.
Since there are 10 equal sectors in the pie chart, each sector is  = 36°, 
and each sector represents 10% of the people in the UK.
Sectors are:
under 15  1539  4059  over 59
