What Blind is
Blind in statistics is a method of collecting and analyzing data without knowing the identity of the test subjects. It is used to reduce bias and ensure that the results of an experiment are not influenced by any preconceived notions of the researcher.
Steps for Blind:
-
Identify the research objectives and create the study design.
-
Develop a blind system to conceal the identities of the test subjects.
-
Collect the data using the blind system.
-
Analyze the data to draw conclusions.
-
Present the results without revealing the identities of the test subjects.
Examples
-
Blind A/B Testing: A/B testing is used to compare two versions of a web page, feature, or product to determine which performs better. Blind A/B testing is when the participants in the test are unaware of which version they are viewing or using.
-
Blind Peer Review: Blind peer review is a process used in academic publishing when the author’s identity is not revealed to the reviewers. This helps ensure that the reviews are objective and unbiased.
-
Blind Sampling: Blind sampling is a type of statistical sampling where the participants are unaware of the purpose of the survey or study. This helps ensure that the results are accurate, as participants are less likely to be influenced by preconceived notions or biases.
