Statistical software plays a crucial role in modern research, data analysis, and decision-making. In pharmacy and biomedical sciences, datasets are often large, complex, and require accurate analysis. Manual calculations can be time-consuming and prone to error, which is why statistical software is widely used for organizing data, performing calculations, running statistical tests, and generating visual outputs such as graphs and tables.
Why Use Statistical Software?
- Handles large datasets efficiently.
- Performs complex statistical tests quickly and accurately.
- Reduces calculation errors.
- Provides high-quality graphical outputs.
- Improves reproducibility and transparency in research.
- Simplifies data entry, manipulation, and export.
Common Statistical Software Used in Research
