A major goal of inferential statistics is to estimate the value of a parameter from the information in a sample. However, the parameter estimate is imperfect due to sampling variability. Thus, the best we can do from the information in one sample is provide a range in which the parameter is likely to be. This range is called a confidence region and is the subject of this module.
After completing this module, you should be able to ...
- Describe the concept underlying confidence regions.
- Construct confidence regions for parameters.
