Mail Survey Method

What It Is

A mail survey method involves sending questionnaires to a sample of respondents through postal mail, allowing them to complete and return the survey at their convenience. A notable example is the American Community Survey (ACS) conducted by the US Census Bureau, which collects data on demographics, housing, and employment through mail surveys. This matters for marketing decision-making as it provides valuable insights into consumer behavior and preferences, helping businesses tailor their products and services to meet customer needs.

Key Terms & Concepts

• Mail Survey Method: A method of data collection where questionnaires are sent to respondents through postal mail.
• Response Rate: The percentage of respondents who return the survey out of the total number of surveys sent. (Example: A response rate of 20% means 20% of the surveys sent were returned.)
• Non-Response Bias: The error that occurs when non-respondents differ significantly from respondents in terms of characteristics or behaviors. (Example: A study found that non-respondents to a mail survey were more likely to be younger and more educated than respondents.)
• Mail Survey Design: The process of designing a mail survey, including selecting a sample, developing the questionnaire, and determining the mode of data collection. (Example: A researcher used a stratified random sampling design to select a sample for a mail survey.)
• Survey Instrument: The tool used to collect data, such as a questionnaire or interview guide. (Example: A survey instrument was developed to measure customer satisfaction with a product.)
• Data Collection: The process of gathering data from respondents, which can be done through various methods, including mail surveys. (Example: Data collection for a market research study was done through a combination of mail surveys and online interviews.)
• Sampling Frame: The population from which the sample is selected. (Example: A sampling frame for a mail survey was the list of customers who had purchased a product in the past year.)
• Sampling Error: The error that occurs when the sample is not representative of the population. (Example: A study found that the sample was biased towards older respondents, leading to sampling error.)
• Mail Survey Costs: The costs associated with conducting a mail survey, including postage, printing, and data entry. (Example: The cost of conducting a mail survey was $10,000, which included postage and data entry.)
• Mail Survey Time: The time it takes to conduct a mail survey, including the time it takes for respondents to complete and return the survey. (Example: The time it took to conduct a mail survey was 6 weeks, from sending out the surveys to receiving the completed responses.)
• Mail Survey Response Rate Formula: The formula used to calculate the response rate, which is (number of completed surveys / number of surveys sent) x 100. (Example: The response rate formula was used to calculate the response rate for a mail survey.)
• Mail Survey Non-Response Bias Formula: The formula used to calculate the non-response bias, which is (number of non-respondents / number of respondents) x 100. (Example: The non-response bias formula was used to calculate the non-response bias for a mail survey.)
• Mail Survey Design Principles: The principles used to design a mail survey, including selecting a sample, developing the questionnaire, and determining the mode of data collection. (Example: A researcher used the principles of mail survey design to develop a survey instrument.)
• Mail Survey Data Analysis: The process of analyzing the data collected through a mail survey, including data cleaning, data transformation, and data visualization. (Example: Data analysis for a mail survey was done using statistical software.)

Common Misunderstandings

• Misunderstanding: Mail surveys are always more expensive than online surveys.
• Correction: Mail surveys can be more expensive than online surveys, but they can also be more cost-effective in certain situations, such as when respondents are difficult to reach or when the survey requires a high level of detail.
• Misunderstanding: Mail surveys are always less reliable than online surveys.
• Correction: Mail surveys can be less reliable than online surveys if the response rate is low or if the data is not collected in a timely manner. However, mail surveys can also be more reliable than online surveys if the survey is well-designed and the data is collected in a systematic way.
• Misunderstanding: Mail surveys are always more time-consuming than online surveys.
• Correction: Mail surveys can be more time-consuming than online surveys if the survey requires a high level of detail or if the data is not collected in a timely manner. However, mail surveys can also be less time-consuming than online surveys if the survey is well-designed and the data is collected in a systematic way.

Quick Application / Identification

Scenario: A marketing researcher wants to conduct a survey to measure customer satisfaction with a new product. The researcher decides to use a mail survey method. What is the primary advantage of using a mail survey method in this situation?

Answer: The primary advantage of using a mail survey method is that it allows respondents to complete the survey at their convenience, which can lead to a higher response rate.

Explanation: Mail surveys are particularly useful when respondents are busy or have limited time to complete a survey. By allowing respondents to complete the survey at their convenience, mail surveys can increase the response rate and provide more accurate data.

Last-Minute Revision
