Formula

The formula to calculate the confidence coefficient is:

\[ C = 1 - \alpha \]

What is a Confidence Coefficient?

The confidence coefficient, also known as the confidence level, is a measure of the reliability of an estimate. It represents the proportion of times that the confidence interval would contain the true parameter if the same population were sampled multiple times. A higher confidence coefficient indicates a higher level of confidence in the estimate. For example, a 95% confidence coefficient means that if the same population were sampled 100 times, the confidence interval would contain the true parameter 95 times out of 100.

Example Calculation

Let's assume the following value:

Using the formula to calculate the confidence coefficient:

\[ C = 1 - 0.05 = 0.95 \]

The confidence coefficient is 0.95 or 95%.
