Inferential Statistics

Easy

applied

Statistical inference is a process through which inference about the population are made based on informations obtained from the:

Type I error

Type II error

sample

critical value

✅ Correct Option: 3

Statistical inference draws conclusions about an unknown population using data collected from a representative subset of it, namely the sample.

Type I and Type II errors and critical values are tools used within that process, not the source of the information.
