- Question 6
6 (a) Outline the strengths and weaknesses of
this source for a researcher interested in
measuring public support for ID cards. (10)
6 (b) Suggest, giving reasons, one alternative
method by which the information could be
presented in order to make it easier for a
researcher to use. (5)
3Outline the strengths and weaknesses of
this source for a researcher interested in
measuring public support for ID cards. (10)
Key word this source means that you must
examine the source of the information very
carefully.
- You should focus on
- the fact that it is an opinion poll
- the fact that the opinion poll was carried out by
MORI, an internationally respected polling
company - how the poll was conducted
4Outline the strengths and weaknesses of
this source for a researcher interested in
measuring public support for ID cards. (10)
- date on which the poll was carried out
- characteristics of the sample
- who has been sampled
- and who has been left out?
- size of the sample
- use of weighting
- use of rounding
- type of questions asked
5- Question asks you to describe and explain the
strengths and weaknesses of this source of
information. - Your answer therefore must be balanced for full
marks. - This means that you must address both the
strengths and the weaknesses.
6- If you do not, your answer will be marked out of
6 marks and not 10. - Your answer though does not have to be equally
balanced. - It is possible to achieve 6 marks for strengths
and 4 marks for weaknesses or vice versa.
7- You will get a lot of credit for developing your
points and for providing exemplification. - Answers that simply list points will not receive
a high mark. - Answers that show a lack of knowledge or
understanding of the issue will not achieve high
marks.
8Company used to carry out the opinion poll MORI
- is an internationally respected polling company
- has a lot of experience in carrying out opinion
polls knows importance of sample size,
characteristics of sample population etc. and has
to stay in business so it has to maintain its
credibility as a polling company. - has to stay in business so it has to maintain its
credibility as a polling company. used by many
high profile companies such as market research,
newspapers and political parties to gauge public
opinion on many issues. - is used by many high profile companies such as
market research, newspapers and political parties
to gauge public opinion on many issues.
9- Question 6
- 2005
- Strengths
Company used weighting to choose the sample
- Weighting ensures that the sample of 1000 people
aged 18 and over are representative of the whole
population of the UK. - Weighting takes into account the following
characteristics of the UK population - its age structure
- its gender structure
- socio-economic structure.
10- Question 6 2005
- Weaknesses
- Many critics of opinion polls wonder how a
sample of around 1000 people can be
representative of the opinions of millions of
people.
Size of sample - 1000
Use of computer rounding
- This will introduce statistical error into the
final results reducing their level of accuracy.
11Research method used advantages and
disadvantages
- Question 6 2005
- Strengths
- Advantages of telephone interviewing using RDD
Random Digit Dialling. - RDD provides a representative probability sample
of all telephone users, unlike telephone surveys
which rely on registered telephone number lists
or directories. (Telephone interviewing has
traditionally been regarded as unreliable because
of the difficulty of obtaining an unbiased
genuinely random sample from the phone book). - ICM and Gallup argued that 94 of the population
could now be contacted by phone. RDD can be used
to contact ex-directory numbers. - Good because people who are ex-directory can now
be contacted mainly female, people living on
their own no longer excluded from the sample.
12Research method used advantages and
disadvantages
- Question 6 2005
- Strengths
- Advantages of telephone interviewing using RDD
Random Digit Dialling. - Telephone interviewing makes it easier and
cheaper to get a wider sample in terms of
geographical positioning avoids clustering which
happens with postal surveys. - Allows for more stringent checks to be carried
out on those who are interviewing because they
are all based in one central position rather than
being spread throughout the country.
13- Question 6
- 2005
- Weaknesses
Research method used advantages and
disadvantages
- Disadvantages of telephone interviewing using RDD
Random Digit Dialling. - 10 of the UK population do not have a telephone
these people are also excluded from the survey
mainly people in the lower socio-economic
groups in society. - Still the problem of obtaining a response-
non-contacts and refusals. - Still the problem of reliability of information
received over the phone. People find it easier to
make false comments on the phone. Is the person
on the phone who they say they are?
14- Question 6
- 2005
- Weaknesses
Reliability of opinion polls as a source of
information
- Opinion polls are inherently limited in their
value as predictors because they only represent a
snap-shot of public opinion at the time the
survey is carried out and the results go to
press. - Opinion polls can only measure what people say.
What people say and actually do are often not the
same and so if used to predict how people might
vote on the issue, opinion polls are not accurate.
15Reliability of opinion polls as a source of
information
- Question 6
- 2005
- Weaknesses
- This poll was carried out between 18 and 23
March 2004 but the results were not published
until 23 April 2004. -
- Some of the respondents may well have changed
their mind on the issue during that time. Results
therefore may not be an accurate reflection of
public opinion.
16- Question 6
- 2005
- Weaknesses
Reliability of opinion polls as a source of
information
- 1972, 1992 General Elections - opinion polls
carried out during the election campaign came
under criticism for high level of inaccuracy. - Opinion polls since 1970 have predicted the
wrong outcome in 5 out 7 elections.
17- Question 6
- 2005
- Weaknesses
Reliability of opinion polls as a source of
information
- Some people are inclined to give politically
correct answers to questions. This will
inevitably increase the chances and size of error
in the result. - Many critics of opinion polls wonder how a
sample of around 1000 people can be
representative of the opinions of millions of
people.
18Type of questions asked in the opinion poll
- Questions are examples of closed questions
they give the respondent a choice of answers from
a directed list. Gives standardised answers.
- Standardised answers make it possible to identify
patterns and make comparisons between the
different groups of people such as between males
and females or between working-class and
middle-class. - Results can be replicated easily to check for
reliability. - Same questions can be repeated at a future date
in order to make comparisons over time
longitudinal study. - Reduces possibility of interviewer bias.
19Type of questions asked in the opinion poll
- With closed questions it is difficult for
respondents to elaborate or develop their answers
in depth. This means that the results may not be
wholly valid in that they do not give a true
picture of the respondents point of view. - Difficult to make generalisations or assumptions
based on the results.
20- Key words information, presented, easier, a
researcher. - Consider how the information is presented by MORI
e.g. - The questions are written in bold.
- The standardised answers are listed underneath.
- The number who responded to each standardised
answer is given beside it in s. - How could this be improved upon?
b) Suggest giving reasons, one alternative way
in which the information in the source could be
presented in order to make it easier for a
researcher to use.
21Primary data that is collected in statistical
form can be presented in a variety of graphical
ways.
- Presenting and
- Analysing Results
Presenting data in this way is very important
because it helps analysis.
22- Presenting and
- Analysing Results
23There is a huge range of graphical
and cartographical techniques available
- Presenting and
- Analysing Results
The technique you use will depend on the type
of data collected
24Whatever the technique chosen, it should be
neat, colourful and annotated, in order to ensure
its impact and effectiveness.
25So all diagrams must have
a labelled axis

26Results of Opinion Poll on Identity Cards
- A comparative bar graph is used to show the
frequency or amount of a number of different
categories or questions. - The bars are drawn with a gap in between them,
and they are coloured or shaded differently. This
is because the categories are unconnected.
27Results of Question (i) To what extent, if at
all, are you in favour of, or opposed to, a
national identity card scheme?
- This method of presenting the results is called a
histogram used when results are connected
yes, no, dont know - It has the same advantages as for a bar graph
however in this example three histograms would
have to be drawn - one for each question
- a different colour could be used for each
question.

30- Presentation techniques
- Pie charts
31- Presentation techniques
- Pie charts
- A pie chart is a good way of showing how a whole
is divided up in this case the answers to the
question. - Each segment of the pie represents the possible
answers to the question. - The size of a segment represents the percentage
support for that answer e.g. Dont know 1. - The use of different colours for each segment
makes it easier to distinguish between the
different levels of support for each answer.
32- Presentation techniques
- Pie charts
- Good way of comparing and analysing the results
for all three questions.
33- No marks are given for the choice of alternative
method of presentation. - Marks are given for the explanation of method
chosen e.g. why that method would be easier for a
researcher. - For full marks you would have to give at least
two well developed points.
