7.6 Summary: Use of confidence intervals¶
In this session we have discussed the concepts underlying confidence intervals and different interpretations of 95% confidence intervals.
We can construct a confidence interval for any estimate, including:
means
proportions
differences in means
risk ratios
regression coefficients
etc.
The way we construct confidence intervals can vary but the basic interpretation of the confidence interval remains the same.
While we have focused on 95% confidence intervals, we can construct other intervals, e.g. 99% confidence intervals. The use of 95% confidence intervals is largely convention.
