Detailed explanation-1: -Descriptive statistics is used to describe the characteristics of the population using a sample. Inferential statistics uses various analytical tools to draw inferences about the population using samples. Measures of central tendency and measures of dispersion. Hypothesis testing and regression analysis.
Detailed explanation-2: -If you want a good example of descriptive statistics, look no further than a student’s grade point average (GPA). A GPA gathers the data points created through a large selection of grades, classes, and exams then average them together and presents a general idea of the student’s mean academic performance.
Detailed explanation-3: -What’s inferential statistics? In contrast to descriptive statistics, inferential statistics want to make a statement about the population. However, since it is almost impossible in most cases to survey the entire population, a sample is used, i.e. a small data set originating from the population.
