| BASIS FOR COMPARISON | DESCRIPTIVE STATISTICS | INFERENTIAL STATISTICS |
| Meaning | Descriptive Statistics is that branch of statistics which is concerned with describing the population under study. | Inferential Statistics is a type of statistics, that focuses on drawing conclusions about the population, on the basis of sample analysis and observation. |
| What it does? | Organize, analyze and present data in a meaningful way. | Compares, test and predicts data. |
| Form of final Result | Charts, Graphs and Tables | Probability |
| Usage | To describe a situation. | To explain the chances of occurrence of an event. |
| Function | It explains the data, which is already known, to summarize sample. | It attempts to reach the conclusion to learn about the population, that extends beyond the data available. |
The difference between descriptive and inferential statistics can be drawn clearly on the following grounds:
- Descriptive Statistics is a discipline which is concerned with describing the population under study. Inferential Statistics is a type of statistics; that focuses on drawing conclusions about the population, on the basis of sample analysis and observation.
- Descriptive Statistics collects, organises, analyzes and presents data in a meaningful way. On the contrary, Inferential Statistics, compares data, test hypothesis and make predictions of the future outcomes.
- There is a diagrammatic or tabular representation of final result in descriptive statistics whereas the final result is displayed in the form of probability.
- Descriptive statistics describes a situation while inferential statistics explains the likelihood of the occurrence of an event.
- Descriptive statistics explains the data, which is already known, to summarise sample. Conversely, inferential statistics attempts to reach the conclusion to learn about the population; that extends beyond the data available.
