under descriptive statistics. Inferential statistics is divided into two i.e confidence interval which give a range of values for unknown parameters of a population by measuring a statistical sample and the test of significance also called hypothesis testing whereby a claim about a population is tested by analyzing a statistical sample. Descriptive statistics only gives numerical measures to describe a set of data but we cannot draw conclusions. Inferential statistics on the other hand allows us

A one-sample test‚ also known as a goodness of fit test‚ shows whether the collected data is useful in making a prediction about the population. One sample tests are used when we have a single sample and wish to test the hypothesis that it comes from a specified population. In this case‚ the following questions are encountered: • Is there a difference between observed frequencies and the frequencies we would expect‚ based on some theory? • Is there a difference between observed and expected
