What is hypothesis in your own words?
In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis. A hypothesis is something more than a wild guess but less than a well-established theory. Anyone who uses the word hypothesis is making a guess.
What are the advantages of hypothesis testing?
Hypothesis testing is a form of inferential statistics that allows us to draw conclusions about an entire population based on a representative sample. You gain tremendous benefits by working with a sample. In most cases, it is simply impossible to observe the entire population to understand its properties.
What are different types of hypothesis testing?
Paired t-tests compare two samples. Chi-Square Test for Independence: tests for an association of significance between two categorical variables in a population sample. Typically used with random sampling. Homogeneity of Variance (HOV): tests the similarity of dispersion parameters in two or more population samples.
