Question

Types of inferential errors (alpha level)

a) Type I and Type II errors
b) Sampling and Non-sampling errors
c) Standard Error and Margin of Error
d) Systematic and Random error.

Answer 1

Type I and Type II errors are types of inferential errors in statistics that occur when a true null hypothesis is rejected or a false null hypothesis is not rejected, respectively.

Step-by-step explanation:

In statistics, there are two types of inferential errors known as Type I and Type II errors. Type I error occurs when a true null hypothesis is rejected, meaning that a significant difference is detected when there is actually none. Type II error occurs when a false null hypothesis is not rejected, meaning that no significant difference is detected when there is one.
