Hypothesis Testing using Standardized Scale: Here, instead of measuring sample statistic (variable) in the original unit, standardised value is taken (better known as test statistic).So, the comparison will be between observed value of test statistic (estimated from sample), and critical value of test statistic (obtained from relevant theoretical probability distribution). In hypothesis testing, Claim 1 is called the null hypothesis (denoted “Ho“), and Claim 2 plays the role of the alternative hypothesis (denoted “Ha“). If your research involves statistical hypothesis testing, you will also have to write a null hypothesis.
