Sampling and sampling frames

Sampling frame - is a numbered list of all the items in the population. (BPP p. 25)

Sampling involves selecting a sample of items from a population. Sampling methods fall into three main groups:

1. Random sampling (every item in the population has an equal chance of being included)

2. Quasi-random sampling (provides a good approximation to random sampling, necessitates the existence of framing)

3. Non-random sampling (sampling frame cannot be established)

(BPP p. 22)

Of course I am going to use non-random sampling, it is the most suitable one for my survey (I need concrete information, described earlier)

Non-random sampling can be:

● Quota sampling (cannot be regarded as ultimately satisfactory in research where it is important that theoretically valid results should be obtained. it can be argued, however, that when other large sources of error exist, such as non-response, it is pointless to worry too much about sampling error)

● Cluster sampling (involves selecting one definable subsection of the population as the sample)

(BPP p. 30-31)

Types of survey

There are two types of survey: the questionnaires and the interview. I have a goal to make a questionnaire and now I am going to explain why. According to BPP “Business Decision Making”, Questionnaires have a lot of advantages:

1. They are relatively inexpensive to administer

2. You can send the exact same questionnaire to a wide number of people

3. They allow the respondent to fill it out at their own convenience

4. There is no opportunity for an interviewer to influence responses or to miss-record them

5. It may be easier to ask personal or embarrassing questions in a postal questionnaire than in a personal interview

6. Respondents may need to look up information for the questionnaire. This will be easier if the questionnaire is sent to their homes or places of work.

(BPP p. 33)

Why has our company chosen Questionnaire instead of interview? The answer is in these two points:

1. You can send the exact same questionnaire to a wide number of people

2. Respondents may need to look up information for the questionnaire. This will be easier if the questionnaire is sent to their homes or places of work

I have no time and ability to organise personal interview to all people who use UK Study Tours. It is impossible. And it is very good that I can use questionnaire because it is really convenient.

Sample frame (where I will select respondance). I will contact partners of UK study tours such as Main support & partners and educational organisations; in fact it is CIE and EF. These organisations have information about all students who is visiting England using these organisations. Moreover, they have different locations such as London, Oxford, Cambridge etc. It means that I can learn about other cities as well which can be very useful for me. That is why I will go to principles and ask about an important information; I hope that it will be easy for me to take this data, because I have good relationships with EF and CIE three times (I have used these two companies and I have studied in Lady Margaret College as summer courses ).
