Difference Between Questionnaire and Schedule

The main difference between questionnaire and schedule is how they are administered: questionnaires are self-administered by respondents, while an interviewer administers schedules. 

In this article, we will deeply explore the difference between questionnaires and schedules. But before we start, let's review the topics we will cover in this article.

Difference Between Questionnaire and Schedule

For better clarity, let's explore Questionnaire vs Schedule in a tabular format:

Aspect	Questionnaire	Schedule
Mode of Administration	Self-administered by respondents.	Administered by an interviewer in real-time.
Interaction Level	Minimal to none, as it's completed independently.	High, with direct interaction between participant and interviewer.
Flexibility in Responses	Responses are limited to the questionnaire format.	Interviewers can adapt questions and probe further based on responses.
Cultural Sensitivity Handling	Less adaptable to cultural nuances in real-time.	More adaptable, allowing for immediate adjustments and clarifications.
Suitability for Online Research	Highly suitable due to easy distribution.	Less suitable, requires more effort to conduct interviews remotely.
Data Richness	Can vary, generally more structured and quantitative.	Tends to be richer, with qualitative insights gained through interaction.
Resource Intensity	Lower, as it can be distributed widely with less effort.	Higher, due to the need for skilled interviewers and more engagement.
Respondent Literacy Requirement	Generally requires literacy for completion.	Can be administered regardless of respondent's literacy level.
Technique Type	Quantitative and Qualitative.	Qualitative.
Grouping Based on Categories	Yes, based on location, age, gender, etc.	May or may not exist.
Distribution Method	Via emails, posts; instructions provided.	Filled by research workers/enumerators.
Personal Contact with Respondents	None, completed independently.	Direct, allowing for clarification and richer data.
Cost	Economical, less expensive even for large samples.	Expensive due to enumerator costs and training.
Coverage	Extensive, can reach inaccessible respondents.	Limited by practicality of sending enumerators.
Accuracy of Information	Higher possibility of wrong/incomplete info.	Reduced inaccuracies due to enumerator presence.
Time for Responding	Respondents have sufficient time to think.	Limited compared to questionnaire method.
Response Filling	By the respondents.	By the enumerators, based on respondents' answers.
Bias Scope	No interviewer bias; responses filled by respondents.	Possible bias or influence by the enumerator.
Response Rate	Lower compared to schedule method.	Higher due to direct engagement.
Respondent Anonymity	Often anonymous.	Respondent's identity is known.
Success Factors	Quality of the questionnaire.	Efficiency, integrity, and honesty of the enumerator.

What is a Questionnaire?

A questionnaire is a set of questions designed to gather information or opinions from a group. It is a common tool used in research, surveys, and feedback gathering. The questions in a questionnaire can be open-ended (respondents answer in their own words) or closed-ended (e.g., multiple choice, true/false, Likert scale). Once the respondents answer the questions, the responses are analyzed to gain insights and make informed decisions.

Questionnaire Examples: Surveys, market research forms, opinion polls.

Key features of a questionnaire include:

• Independent Completion: Filled out by respondents alone, ensuring anonymity and minimizing bias.
• Standardized Format: Uniform questions guarantee consistent data across participants.
• Data Focus: Can collect data in the form of numerals (quantitative data) and words and figures (qualitative data). It also allows for gathering mixed data (quantitative data + qualitative data). 
• Versatile Uses: Applied in diverse fields for insights into opinions, learning outcomes, and customer satisfaction. 

What is a Schedule?

A schedule is a tool interviewers use to collect data or opinions from individuals through direct interaction. It contains a set of questions and space to note down the answers. The schedule proves effective regardless of whether participants are literate or not, making it a robust choice for data collection in diverse settings.

Schedule Examples: Face-to-face interviews, telephone surveys, field research interviews.

Key features of a schedule include:

• Interviewer Administration: Directly facilitated by an interviewer, enabling immediate clarification and deeper probing of responses.
• Interactive Format: Encourages a dynamic exchange between the interviewer and respondent, potentially yielding richer data.
• Adaptability: Questions can be adjusted or followed up on the spot based on the respondent's answers, allowing for greater flexibility.
• In-depth Data Collection: It helps gather qualitative insights, though it can also be structured for quantitative analysis.

Key Differences Between Questionnaire and Schedule

Here are the key differences between questionnaire vs schedule:

• The questionnaire is self-administered, allowing individuals to answer questions independently. Meanwhile, an interviewer or observer administers the schedule, requiring direct interaction for asking or prompting questions.
• While a questionnaire captures individual perspectives and experiences, a schedule records factual information and observations.
• The questionnaire gathers both quantitative and qualitative data to provide a broad understanding of the subject matter. On the other hand, schedule primarily collects qualitative data.
• Examples of questionnaires include surveys, market research forms, and opinion polls, showcasing its versatility in capturing a wide range of personal insights. In contrast, examples of schedules such as interview guides, observation logs, and lesson plans indicate its utility in documenting factual details and tracking occurrences.
