9 Efficient Data Collection Methods and How to Choose the Best One

In a data-driven world, the approach toward acquiring new data defines business outcomes and generates innovative avenues of profit. Understanding the different data collection methods is therefore key to consolidating the highest-quality data. But what are the different data collection methods out there and how do they ensure an accurate conversion of unstructured data into actionable insights? Comprehensive data collection is the first step to data purity. A 2021 Data Science Process Alliance report underlines that 85% of big data projects fail due to the incorrect application of data-cleaning and data-modeling procedures. Let’s delve into some of the best data collection techniques, their benefits and risks, and how to choose the one that’s best suited to your needs.

What is Data Collection?

What is Data Collection?

The various processes that organizations undertake to consolidate unstructured data and extract valuable relevant information, fall under the umbrella category of data collection. There are two major categories of data collection methodsprimary and secondary. Primary data collection refers to the unique unused data collected from first-hand experiences while secondary data is typically derived from historical sources.

Data Collection Methods

Data collection methods heavily influence data hygiene. Back in 2015, IBM pointed out that businesses worldwide lose around $3 trillion to inaccuracies in data management. Gartner’s recent analysis corroborates IBM’s claim that the yearly cost of poor-quality data is a staggering $12.9 million. Superior data collection practices are a central aspect of data management and ensure that the available information is accurate, structured, and sophisticated.

Data Collection Method 1: Surveys

Surveys collect first-hand information from specific target groups (depending on the industry and choice of information) to gather insights aimed at improving the quality of products and services. There is an abundance of software systems that offer a comprehensive range of questionnaires and readymade survey templates. 

Benefits

  • Efficient and time-effective 
  • Does not require heavy technical knowledge to operate
  • Can be remotely administered
  • Comprises broad ranges of data sets, such as subjective opinions, beliefs, and attitudes 

Potential Downsides and Risks

  • Subjective opinions may not be accurate
  • Nonresponsive questions lead to data bias
  • Close-ended questions lead to lower data validity 
  • Participants are wary of answering questions that may project them in an adverse fashion

Data Collection Method 2: Tracking Transactions

This method comprises various data points associated with a particular transaction, such as its geographical location, the exact time of the transaction, its price points, the deployed payment methods etc. The aim is to duly map consumer behavior and market dynamics in various fields, from banks to marketing agencies.

Benefits

  • Enhanced consumer experience tailored according to information
  • Consistent information storage without any data tampering
  • Instantaneous data collection 
  • Accurate predictive analysis of consumer behavior 
  • Superior diagnostics that optimize operations and data management
  • Reduces failures in transaction processing

Potential Downsides and Risks

  • Demands complex analytical processes 
  • Chances of database collapse are high due to their complexity
  • Databases are non-writable so changes in copies won’t get reflected in the original

Data Collection Method 3: Observing People

It is a qualitative data collection method that comprises watching, listening, and recording subjects’ behaviors, characteristics, and attitudes in their natural environments. The aim is to observe patterns and gain insights about their psychological characteristics.

Benefits

  • It requires minimum technical knowledge to perform observations
  • Puts the subjects at ease as they are in their natural circumstances and territories 
  • It is extremely beneficial for sensitive subjects unable to read, write, or speak
  • Data accuracy is very high as in-depth information about subjects is guaranteed
  • Works efficiently on infants as the focus is primarily on verbal/visual information

Potential Downsides and Risks

  • One of the most expensive data collection methods
  • Demands sophisticated tools for analyzing observations
  • The process is time-consuming and subjects may lose interest in following through with the extensive process
  • No chance to objectively study the past of the subjects

Data Collection Method 4: Focus Groups

It is a qualitative data collection technique that carefully chooses a small number of subjects who share certain common characteristics and interests. They are provided with a topic to discuss, the aim being to observe their behaviors and differing perspectives about the same issue. 

Benefits

  • Provides the best-quality in-depth information on perceptions, experiences, attitudes, and beliefs of select groups
  • Very cost-effective and easy to set up
  • Focus groups invite conversations that may be difficult to bring into observational models
  • More candid conversations lead to high data accuracy
  • Aids other quantitative analytical models with deep or sensitive insights

Potential Downsides and Risks

  • Success rates depend on unbiased hosting by the facilitator
  • Chance of domination by subjects with high verbal intelligence
  • The process requires meticulous planning in advance
  • The acquired information is not universal 

Data Collection Method 5: One-on-One Interviews

This is one of the most ubiquitous data collection methods applicable across industries to analyze a wide range of differing opinions and perspectives. 

Benefits

  • Attitudes, emotions, behaviors, body language, and nonverbal gestures can be captured
  • The process is very flexible 
  • Enhances individualized healthcare and social research
  • Accurate screening of participants 
  • Can be administered online or remotely

Potential Downsides and Risks

  • The process is expensive because it involves hiring staff to find interested participants
  • The success rate depends on the efficiency of the interviewer
  • Makes generalized conclusions a difficult feat to achieve

Data Collection Method 6: Online Tracking, Pixels, and Website Cookies

They refer to a set of tools that track user behavior to collect and transfer consumer information from websites to analytical software systems. Tracking pixels and website cookies have become indispensable marketing tools for advertising and marketing services.  

Benefits

  • Provides deep insights into user behavior, page performance, and web traffic
  • Strengthens and extends databases with efficient web analysis tools 
  • Efficient strategizing of social media campaigns  
  • Enhanced user personalization and website experience

  • Selling of personal information to third parties comes with a heavy risk of privacy breaches for users

Data Collection Method 7: Monitor Social Media Channels

This data collection method gathers information on real-time user behavior. It involves tracking the engagement reach of posts, the growth of follower count, and frequency of profile visits. It also analyzes brand sentiments and impressions, such as likes and follows on individual posts.
