5.4.4. Surveys

Survey is probably the best known sociological method, one that is now so much a part of modern public life that it has become commonplace. Today it is used all over the world in all sorts of contexts going well beyond the concerns of sociology alone.

A survey is a method used to gather data from a group of people to understand their opinions, behaviors, or characteristics. It's widely recognized and utilized in various fields, including sociology, marketing, and political science. This method has become integral to our society, often used to gauge public sentiment on different issues, which indicates its significance. For example, surveys are regularly conducted to predict election results or gather feedback on products.

Think of a survey like asking a group of friends to vote on where to eat dinner. By asking everyone for their opinion, you can determine the most popular choice, just as a survey gathers opinions from many people to understand a common view.

as the word itself suggests, a survey is an attempt to provide an overview. It is a comprehensive or wide-ranging perspective on some subject based on information obtained from a carefully chosen representative set of people. Such people are usually referred to as 'respondents' — they respond to questions asked of them by the researchers.

The primary purpose of a survey is to collect a wide-ranging overview of a topic by asking well-structured questions to a selected group of people, called respondents. Researchers design surveys to obtain a snapshot of opinions or behaviors within a specific population, ensuring that the participants represent diverse subgroups of that population.

Imagine conducting a survey about favorite ice cream flavors in a school. You wouldn't just ask your friends; you would ensure to include a variety of students from different grades and backgrounds. This way, you can get a representative idea of what flavors are popular among all students, much like how a proper survey works.

Survey research is usually done by large teams consisting of those who plan and design the study (the researchers) and their associates and assistants (the latter are called 'investigators' or 'research assistants'). The survey questions may be asked and answered in various forms.

Conducting a survey usually requires a team effort. Researchers develop the questions and objectives of the survey, while assistants help in administering the survey, either through face-to-face interaction or digitally. The questions can take different forms, including multiple-choice, open-ended, or Likert scale formats, allowing for flexibility and clarity in responses.

Think of organizing a school event. You have a main planner (researcher) who decides what needs to be done, and a team (assistants) that helps carry out different tasks such as sending invites, collecting feedback, or setting up. Similarly, in surveys, it takes a team to ensure questions are asked and data is collected effectively.

The survey’s main advantage as a social scientific method is that it allows us to generalise results for a large population while actually studying only a small portion of this population.

One of the key benefits of surveys is their ability to extrapolate results from a small, representative sample to a larger population. This means that, rather than interviewing every single person in a wide-ranging demographic, researchers can obtain meaningful data that reflects broader societal trends by involving a limited but representative group.

Picture a teacher who wants to know how students feel about a new school policy. Instead of interviewing every student, the teacher can survey a few classes. If done correctly, the feedback from those students will help understand the overall sentiment among the entire student body, just like surveys aim to do.

The sample survey is able to provide a generalisable result despite being selective by taking advantage of the discoveries of a branch of statistics called sampling theory.

To ensure surveys yield reliable results, sampling theory plays a pivotal role. Selecting a sample is about representing different subgroups within a population fairly. Researchers use statistical techniques to ensure that the sample reflects the diversity of the entire population, thereby maintaining validity and minimizing biases.

Like selecting fruit for a fruit salad, if you want to represent a type of fruit, you shouldn't only choose apples; instead, you’d want a mix of fruits. Similarly, in surveys, diverse samples lead to more accurate reflections of the population being studied.

Broadly speaking, the sample selection process depends on two main principles. The first principle is that all the relevant sub-groups in the population should be recognised and represented in the sample.

In any survey, it's crucial to include and represent the different sub-groups within the population to ensure that their perspectives contribute to the findings. This understanding of various segments, such as age, gender, and socio-economic status, helps in collecting consistent and representative data that reflects the overall population view.

Imagine organizing a community event. To truly represent the community, you’d need to involve people of different ages, occupations, and interests. If you only ask one group, like just the youth, you won’t capture the diverse views and needs of the whole community, much like how surveys work.

The second principle of sample selection is that the actual unit — i.e., person or village or household — should be based purely on chance. This is referred to as randomisation, which itself depends on the concept of probability.

Randomization is vital for eliminating bias in survey samples. By ensuring that each individual or household is selected at random, researchers can create a sample that accurately represents the larger population without any predisposition towards one group or another. This process is similar to drawing names from a hat where each name has an equal chance of being chosen.

Think of a lottery. Every ticket has the same chance of winning. The fairness of a lottery ensures that winners are chosen randomly, just like how researchers ensure that every member of a population has an equal chance to be included in a survey sample.

However, like all research methods, survey also has its disadvantages. Although it offers the possibility of wide coverage, this is at the cost of depth of coverage.

While surveys are great for gathering data from many people, they often sacrifice depth for breadth. Due to the large number of participants, individual responses might not be explored in detail, and sensitive topics can be difficult to address as respondents may provide superficial answers rather than engaging deeply with the questions.

Consider a restaurant survey that asks diners about their meal. While many people can give star ratings, the restaurant may miss out on rich feedback about why diners felt a certain way about their experience. Depth can be sacrificed for volume, similar to how surveys can gather numbers but sometimes lose important insights.
