1. Cost-effective: Questionnaires and random sampling are cost-effective methods of data collection as they can reach a large number of respondents without the need for face-to-face interviews or focus groups.
2. Time-efficient: These methods are also time-efficient as they can be distributed and completed quickly, allowing researchers to gather data in a timely manner.
3. Representative sample: Random sampling ensures that every member of the population has an equal chance of being selected, leading to a more representative sample and more accurate results.
4. Anonymity: Respondents may feel more comfortable providing honest and candid responses in a questionnaire as they can remain anonymous, leading to more accurate data.
5. Standardization: Questionnaires allow for standardized data collection, ensuring that all respondents are asked the same questions in the same format, making it easier to analyze and compare results.
6. Flexibility: Questionnaires can be easily adapted and modified to suit different research objectives and target populations, making them a versatile tool for data collection.

Advantages of Questionnaires:
- Reach a large number of respondents: Questionnaires can be distributed to a wide geographic area, increasing the sample size and generalizability of the findings.
- Collect data anonymously: Participants can respond to questionnaires without providing personal information, which may encourage honest responses on sensitive topics.
- Standardized response format: Questionnaires ensure that all respondents answer the same questions in a consistent manner, enhancing data comparability.
- Low cost: Questionnaires can be administered online or through mail, making them a cost-effective data collection method.
- Efficient: Questionnaires can be completed in a relatively short period, allowing for quick data collection.
Advantages of Random Sampling:
- Unbiased representation: Random sampling ensures that every member of the population has an equal chance of being selected, reducing bias and providing a representative sample.
- Generalizability: Results from random samples can be generalized to the entire population with confidence, ensuring that the findings are applicable beyond the sample.
- Control for confounding variables: By randomly assigning participants to groups or conditions, confounding variables are evenly distributed, allowing researchers to isolate the effects of the independent variable.
- Increased accuracy: Random sampling reduces the likelihood of biased results due to systematic selection or overrepresentation of certain subgroups.
- Objective and transparent: The random selection process makes it difficult to manipulate the sample and ensures that the sampling method is transparent and reproducible.
