1. Common bias test
A common bias test is a process of check the responses for common bias. The concept of
common bias is a situation when variations or bias in responses are caused due to instruments
which lead to result contamination by the “noise”. In order to ensure that the responses which are
gained from respondents are free from any bias and noise, the common bias test is used.
