Answer 1

The primary purpose of inferential statistics is to make inferences from our data to more general conditions. More specifically it used to make inferences or conclusions about the population and its parameters. Now our research study, inferential statistics could be primarily used for two major purposes:

1. Parameter Estimation : For example a sample data could be used to obtain an unbiased estimated value for some parameter like the population mean or population standard deviation and so on.
2. Hypothesis testing: This is where you can use sample data to answer research study questions. For example, we might be interested in finding out whether some independent variable like age has an affect on the blood pressure of a person which is the dependent variable. ANOVA test is used for the same.
