CONFIDENCE LEVEL Meaning and
Definition
-
Confidence level refers to the degree of certainty or reliability in the results of a statistical analysis or research study. It refers to the estimate of the range within which the true population parameter lies. In simpler terms, the confidence level indicates how confident we are that the results from a study accurately represent the population being studied.
In statistical terms, confidence level is expressed as a percentage, typically ranging from 90% to 99%. It represents the probability that the true value of a parameter falls within a certain interval. For example, if a study reports a confidence level of 95%, it means that there is a 95% probability that the true value of the parameter falls within the stated range.
The confidence level is directly related to the concept of margin of error. The margin of error refers to the maximum amount by which the estimate may differ from the true value. A higher confidence level usually corresponds to a wider margin of error, as it aims to provide a higher degree of certainty in the result.
Choosing an appropriate confidence level depends on various factors, including the importance of the study, the desired precision of the results, and the level of risk acceptable for making decisions based on the findings. Researchers and analysts often strive for a balance between having a high confidence level to ensure reliability and achieving a reasonable margin of error to maintain practicality and feasibility.

The term "level" refers to the degree or extent of something, and when combined with "confidence", it refers to the degree or level of trust or certainty in the validity or accuracy of something.
