Problem 78

Given information

The potential problems are as below:

 The sample size is low to do any conclusions. Many things can influence this. But when most people refuse to participate, then the sample may not have the same characteristics. We can describe the problem in the following ways:

•  Self - selected Samples
•  Sample Size Issues
•  Undue Influence
•  Self-Funded or Self -Interest Studies

Step-by-step explanation

Here are the definitions of the potential problem:

 Self-Selected Samples: A sample is self-selected when the inclusion or exclusion of sampling units is determined by whether the units themselves agree or decline to participate in the Sample, either explicitly or implicitly. When survey units volunteer gets included in the Sample, this introduces self-selection.

 Sample Size Issues: Sample size refers to the number of participants or observations included in a study. This number is to be represented by n. The size of a sample influences two statistical properties: 1) the precision of our estimates and 2) the power of the study to conclude. The good maximum sample size is usually 10% as long as it does not exceed 1000.

 Undue Influence: Undue influence occurs when an individual can persuade another's decisions due to the relationship between the two parties. The more powerful individual uses this advantage to coerce the other individual into making decisions that might not be in their long-term best interest.

 Self-Funded or Self-Interest Studies: Self-interest refers to actions that elicit personal benefit. Self-interest study – a bias that can occur when the researchers have an interest in the outcome. Response bias – when the responder gives incorrect responses for any reason.
