11.1 What is Hypothesis testing
Hypothesis testing
is a statistical method used to determine if there’s enough evidence in a sample of data to draw conclusions about a population.
It helps you make informed decisions about whether a specific assumption or claim about a population is likely to be true or not.
In simple terms, it involves setting up two competing statements, the null hypothesis (H0)
and the alternative hypothesis (Ha)
, and then collecting and analyzing data to see which statement is more likely to be supported by the evidence.
