In research methodology, schedule and survey are two commonly used tools for data collection. While both aim to gather information from respondents, they differ significantly in their approach, administration, and usage. Here’s a detailed comparison:
| Basis of Difference | Schedule | Survey |
|---|---|---|
| Definition | A schedule is a structured set of questions filled out by a researcher or enumerator during a personal interview with the respondent. | A survey is a method of data collection where the respondent reads and fills out the questionnaire on their own, either online or on paper. |
| Mode of Administration | Interviewer-administered | Self-administered |
| Presence of Investigator | The investigator or enumerator is present and helps record the responses. | The respondent fills out the form without assistance. |
| Data Accuracy | Often more accurate due to clarification and probing by the investigator. | May have errors if the respondent misinterprets questions. |
| Cost and Time | Generally more expensive and time-consuming due to the need for trained interviewers. | More economical and faster, especially for large populations. |
| Literacy Requirement | Can be used with illiterate respondents because the interviewer reads and explains the questions. | Suitable for literate respondents who can read and write independently. |
| Flexibility | Allows for better explanation, probing, and clarification of questions. | Limited flexibility—relies on the clarity of written questions. |
| Examples of Use | Census interviews, field research, health surveys with in-person interviews. | Online feedback forms, market research surveys, email questionnaires. |
Summary
-
Use a schedule when detailed, accurate data is required and face-to-face interaction is feasible.
-
Use a survey when you need to collect data from a large group quickly and cost-effectively, especially when the respondents are literate and self-reliant.
