Data Collection: Definition, Methods, Example and Design
Home Consumer Insights Market Research. Data collection is defined as the procedure of collecting, measuring and analyzing accurate insights for research using standard validated techniques. A researcher can evaluate their hypothesis on the basis of collected data. In most cases, data collection is the primary and most important step for research, irrespective of the field of research. The approach of data collection is different for different fields of study, depending on the required information.
The most critical objective of data collection is ensuring that information-rich and reliable data is collected for statistical analysis so that data-driven decisions can be made for research. There are pros and cons to each of these modes. In-Person Interviews Pros: In-depth and a high degree of confidence on the data Cons: Time consuming, expensive and can be dismissed as anecdotal. Mail Surveys Pros: Can reach anyone and everyone — no barrier Cons: Expensive, data collection errors, lag time.
Phone Surveys Pros: High degree of confidence in the data collected, reach almost anyone Cons: Expensive, cannot self-administer, need to hire an agency. It is expensive to regularly conduct interviews and not conducting enough interviews might give you false positives.
Validating your research is almost as important as designing and conducting it. The other issue here is sample size. To be confident with your research you have to interview enough people to weed out the fringe elements. A couple of years ago there was quite a lot of discussion about online surveys and their statistical validity. The fact that not every customer had internet connectivity was one of the main concerns. Although some of the discussions are still valid, the reach of the internet as a means of communication has become vital in the majority of customer interactions.

United States FCC rules prevent automated dialing and calling cellular phone numbers and there is a noticeable trend towards people having cellular phones as the only voice communication device.
This introduces the inability to reach cellular phone customers who are dropping home phone lines in favor of going entirely wireless. Even if automated dialing is not used, another FCC rule prohibits from phoning anyone who would have to pay for the call. Learn more: Qualitative Market Research. Surveys, where the data is collected via different modes online, paper, phone etc.
It is fairly straightforward and easy to have an online survey and have data-entry operators to enter in data from the phone as well as paper surveys into the system.
The same system can also be used to collect data directly from the respondents. Learn more: Survey Research. Data collection is an important aspect of research. To conduct research about features, price range, target market, competitor analysis etc. The marketing team can conduct various data collection activities such as online surveys or focus groups. For conducting a focus group, the marketing team should decide the participants as well as the mediator. The topic of discussion and objective behind conducting a focus group should be made clear beforehand so that a conclusive discussion can be conducted.
Data collection methods are chosen depending on the available resources. For example, conducting questionnaires and surveys would require the least resources while focus groups require moderately high resources. What can we do better? Online surveys are just another medium to collect feedback from your customers , employees and anyone your business interacts with. With the advent of Do-It-Yourself tools for online surveys, data collection on the internet has become really easy, cheap and effective.
It is a well-established marketing fact that acquiring a new customer is 10 times more difficult and expensive than retaining an existing one. This is one of the fundamental driving forces behind the extensive adoption and interest in CRM and related customer retention tactics. In a research study conducted by Rice University Professor Dr. Paul Dholakia and Dr. Vicki Morwitz, published in Harvard Business Review, the experiment inferred that the simple fact of asking customers how an organization was performing by itself to deliver results proved to be an effective customer retention strategy.
In the research study, conducted over the course of a year, one set of customers were sent out a satisfaction and opinion survey and the other set was not surveyed. In the next one year, the group that took the survey saw twice the number of people continuing and renewing their loyalty towards the organization.

Surveys should be considered as a critical tool in the customer journey dialog. The research conducted by Paul Dholakia and Vicki Morwitz shows that surveys not only get you the information that is critical for your business, but also enhances and builds upon the established relationship you have with your customers.
The data collected via online surveys is dominantly quantitative in nature. Review the basic objectives of the study. What are you trying to discover? Online surveys are just one way of collecting and quantifying data.
Learn more: Qualitative Data. Online surveys have over the course of time, evolved into an effective alternative to expensive mail or telephone surveys. There are a few conditions which need to be met to online surveys however that you must be aware of.
If you are trying to survey a sample which represents the target population, please keep in mind that not everyone is online. Moreover, not everyone is receptive to an online survey also.
Generally, the demographic segmentation belonging to younger individuals are inclined towards responding to an online survey. Writing great questions can be considered by an art. Art always requires a significant amount of hard work, practice, and help from others.
A small change in content can produce effective results. Intense words such as — prohibit or action, which represent control or action also produce similar results. Sometimes the content is just biased. Questions should always have reference to the intended context, questions placed out of order or without its requirement should be avoided. Generally, a funnel approach should be implemented — generic questions should be included in the initial section of the questionnaire as a warm-up and specific ones should follow and towards the end, demographic or geographic questions should be included.
Multiple choice answers should be mutually unique in order to provide distinct choices. Overlapping answer options frustrate the respondent and make interpretation difficult at best. Also, the questions should always be precise. This question is vague.
In which terms is the liking for orange juice is to be rated? Asking about industry related terms such as caloric content, bits, bytes, mbs, and other such terms and acronyms can be confusing for respondents.
Ensure that the audience understands your language level, terminology and above all, the question you ask. What suggestions do you have for improving our shoes? The question is about quality in general, but the respondent may offer suggestions about texture, the type of shoes or variants. There will always be certain questions which cross certain privacy rules and since privacy is an important issue for most people, these questions should either be eliminated from the survey or not kept as mandatory.
Survey questions about income, family income and status, religious, and political beliefs etc. Unbalanced answer options in scales such as Likert Scale and Semantic Scale may be appropriate for some situations and biased in others. When analyzing a pattern in eating habits, a study used a quantity scale that made obese people appear in the middle of the scale with the polar ends reflecting a state where people starve and an irrational amount to consume. There are cases where we usually would not expect poor service such as hospitals.
What is the fastest and most convenient ISP for your location? The fastest ISP would be expensive and the less expensive ones will most likely be slow. To understand both factors, two separate questions should be asked. The use of long questions will definitely increase the time taken for completion which will generally lead to an increase in the survey dropout rate.
Multiple choice questions are the longest and most complex and open-ended questions are the shortest and easiest to answer. Though you're welcome to continue on your mobile screen, we'd suggest a desktop or notebook experience for optimal results. Survey Software Our flagship survey solution.

6. What is involved in collecting data – six steps to success
Metrics details. With the rapid development of urbanization, collecting and analyzing traffic flow data are of great significance to build intelligent cities. The paper proposes a novel traffic data collection method based on wireless sensor network WSN , which cannot only collect traffic flow data, but also record the speed and position of vehicles. On this basis, the paper proposes a data analysis method based on incremental noise addition for traffic flow data, which provides a criterion for chaotic identification. The method adds noise of different intensities to the signal incrementally by an improved surrogate data method and uses the delayed mutual information to measure the complexity of signals. Based on these steps, the trend of complexity change of mixed signal can be used to identify signal characteristics.

This synthesis will be of interest to traffic engineers, highway planners, and others concerned with the collection of traffic data for traffic engineering studies, for long-range planning, and for evaluation of traffic law enforcement. Information is presented on current practice in traffic data collection and analysis. Although types of highway traffic data collected over the past 50 years have not changed significantly, the quantities, analysis procedure, and presentations of these data have changed as a result of changing policies, operational concerns, and capabilities resulting from new technologies. This report of the Transportation Research Board describes the technology both hardware and software that is being used for traffic data collection, and discusses technological advances that have not yet been applied to the acquisition and presentation of traffic data.
