Market research is the most common process for all businesses to get insights about the market and its customers. To perform market research, probability samples are drawn from the population to get the underlying trend of the market. 

The random sample selection process is usually the most reliable way to form a representational sample of a population, although this does not always guarantee a perfect sample. After implementing numerous statistical tools to create the best random samples there will always be the change that it would be different.

To eliminate and reduce these error market research professional uses different procedures and methods. This could help to ensure accurate characteristics of the population. The researcher’s aim is to design processes that reduce or eliminate the error.  But in reality, this elimination is costly and often difficult to achieve.

Survey error is inevitable when getting a sample, we take g error is inevitable when getting a sample, we take measures to estimate and reduce sampling error. 

The margin of error that you usually see with survey outcomes is an estimation of sampling error. As it’s just an estimate, there exists a small.

The diagram below explains the flow chart of sampling error: 

Common Types of  survey Errors

• Population Specification Error:-This error happens when the researcher does not recognize who they should survey. example:  create a survey about rice consumption at home. Whom to survey? who should be surveyed – entire family, mother, children? The mother makes the buying decision, but the kids change her selection.
• Sample Frame Error:– this error occurs when the wrong subpopulation is used in the selection of a sample.
• Selection Error:-This occurs when respondents volunteer their cooperation in the study. these errors can be controlled using extra lengths for participation. If a reply is not obtained, then the second survey is done using alternate methods like telephone or personal interview.
• Sampling Errors:-These errors generally occur due to variations in the number of representatives that respond in the sample chosen. These errors can be controlled by

1. careful sample designs
2. large samples
3. multiple contacts for a response.

• Complicated language:–  this occurs when the researchers uses complex language in the survey making it difficult for the researcher to understand the question thereby randomly answering questions.

Ways To Avoid Sampling Error 

• Keep your survey question easy and directing to the purpose of your study. 
• Lengthy questionnaires distract the respondents making them answering the questions randomly. So try keeping the questionnaire compenshive and short (minimum questions ) it should take more than a few minutes to fill out the questionnaire.
• The main intent of getting open ended questions is to understand the mindset and thoughts. Don’t use too many open ended questions making the respondents feel like they are writing essays instead of filling up the questionnaire and will eventually distract them. 
• Use similar type of questions by using Likert scale making it easy for researchers to interpret. It’s easy for respondents to give valuable feedback in one go by using rating scale.
• Sending it across lot many respondents would make the sample size sufficiently large. A large size of sample will make the study more effective but the respondents should relevant and reliable.
• Use digital platform to create survey to increase the ease of filling and giving some additional feedback , coupons codes to increase the responsive of the respondents.

All in all, surveys can be a comprehensive tool to help you collect feedback! By avoiding these blunders, you can place your study on the way to success!
