Usefulness

~~Allows~~allow for a “real-time” expression of opinions and attitudes on a particular topic. It might only take less than 6 days to conduct a telephone survey. This is very useful for marketers and politicians who might want to change their strategy, or tactics, quickly.

For political scientists, sociologists, and economists, survey results allow for a snap-shot of public opinion at different points in time. This allows to see shifts in opinion, or the impact of specific events on the views. Surveys can also allow for cross-sectional analysis since they often measure socio-demographic variables, such as gender, or mother-tongue language, as well as political opinions, or market preferences.

In politics, allows to identify shifts in opinions, and relate them to a particular event (speech, riot, etc.)

Business people need them to prepare marketing strategies, advertising campaigns, etc.

Sampling

Hopefully RANDOM and LARGE, especially when using a questionnaire.

This is possible using a list of the population such as a local phonebook, which is difficult to achieve with email and internet surveys.

With interviews, samples are non-random and rather small.

Types of Surveys

Cross-sectional: compare many independent variables to a dependent variable
Longitudinal: compare a few variables over time
- Trend: similar samples taken at different time points
- Panel: same sample followed through time

Instruments

Questionnaire: set question list, closed-ended questions, larger sample
- In-person
- Telephone
- Internet
- Group
Interview: starting question list, open-ended questions, smaller sample
- Field interview
- Formal Face-to-face interview

Scientific Power

Mostly descriptive studies, which focus on 5Ws.

May also be used for explanatory studies which validate hypotheses and their causal relationships (why), using cross-sectional tables.

Warning – “Surveys” are often used by corporations as a commercial ploy to engage a sales pitch, or to build an email mailing list for future advertising.
