Drawing a line graph

To draw a line graph we first need to look at the data we are going to use to draw the graph, where do the variables begin and end.

Remember that a line graph is made up of the following elements:

5.  Look at the following set of data which are the average daily temperatures for Wales in March 2009.

Date / 1 / 2 / 3 / 4 / 5 / 6 / 7 / 8 / 9 / 10 / 11 / 12 / 13 / 14 / 15
Temp(oC) / -4 / -8 / -3 / 5 / 12 / 14 / 10 / 13 / 10 / 12 / 6 / -4 / -3 / 5 / 8

Draw the graph on the grid below

6.  To be able to draw a bar chart, histogram or pie chart, a frequency table must be completed. The following are the marks gained by a class of 20 students in a test.

Complete the frequency column and create a Pie Chart of the results.

Marks / Tally / Frequency
0 -10 / || / 2 (two learners got 0-10 marks)
11 - 20 / |||
21 - 30 / |||| ||
31 - 40 / ||||
41 - 50 / |||
TOTAL

7.  Use a pie chart to illustrate the data given below:

180 sixth form students were asked what they intended to do next year.

54
40
62
24 / going to university
staying at college
going into employment
no firm intention

8.  At a concert, the ages of 120 people were recorded as:

Under 20
20 – 29
30 – 39
40 – 59
60 and over / 15
30
22
24
29

Draw a pie chart using this data.

9.  Thirty people were surveyed in a shopping centre and asked their ages. These are displayed below.

54 41 65 46 66 37

32 71 34 73 15 26

64 22 54 8 58 43

14 57 43 52 24 68

43 39 59 35 48 49

a) Draw a tally-frequency table.

b) Using the data in your frequency table, construct a table to calculate the angles in a pie chart.

c) Draw and fully label a pie chart to show the percentage values.
