Explanation

When testing a null hypothesis, there are two types of errors that can occur:

• Type I error (α-error): Rejecting the null hypothesis when it is actually true (false positive).
• Type II error (β-error): Failing to reject the null hypothesis when it is actually false (false negative).

Explanation

Using SPSS (Statistical Package for the Social Sciences) or other statistical software offers several advantages over calculating statistics by hand:

• Reduces errors: SPSS minimizes the chance of making errors in calculations, as it performs computations accurately and efficiently.
• Time-saving: SPSS can process large datasets and perform complex analyses much faster than manual calculations.
• Recognized software: Many researchers and organizations use SPSS, making it a widely recognized and accepted software package in the field of statistics and research.
• Transferable skill: Knowing how to use SPSS equips you with a valuable and transferable skill, beneficial for future research, academic, or professional endeavors.

Explanation

• Control charts and procedures of descriptive statistics used to enhance a process are classified as Statistical Process Control (SPC) tools.
