Dear Suhaib,

The most effective data collection methods are often those involving a social element, e.g. a phone call rather than an online approach.

In terms of analysis, it depends what type of data you are planning to capture and your design. Generally, it sounds like you should have enough cases to detect a medium to large effect.

You ask an interesting question as I recommend you to use MADM or MODM methods for you purpose. Please note that you wanna examine the small society in which it is better to start by using the following levels in your study:

Should you have a look at my articles as follows, it will show how can you be successful in your purpose as I hope these will be helpful for you.

Dear Suhaib

It is important the extension of the questionnaire you intend to apply and the answer format of answer you deploy to your questions. Picking up the information by phone call is appropriate for short questionnaires and simple response formats. If the questionnaire is long, the response formats are more complex and if the respondent needs to consult some information, it is better an online questionnaire.

On the other hand I agree with Peter in the size effect you can detect with your sample size. According to Cohen (1992) with your sample size (considering the response rate and being conservative, would be 30 individuals) and considering an α-level of .05, you would have enough cases to detect a large effect (r=.5).

Consider that as the size effect you want to detect is smaller, the sample size should be larger.

Greetings and luck in your research.

Population size is quite small to come to a quantitative meaningful assessment. However, design a good questionaire and include various types of service providers. Introduce Factor Analysis method for understanding and making classes of common traits.

Hallo,

Please see this file about

Data Collection and Sampling

Dear Suhaib

You have two choices; The first is conduct this study by random sampling, calculate sample volume, distribute paper questionnaire or online questionnaire (desired), ..., and use one sample t-test but note that the reliability of this study or this method is rather low because of low N. 

The second choice is study all of participants by census method and just describe the variables by descriptive statistics. Note that this method of study like the first one is not perfect.
