Overview of Statistical Analysis
Statistical analysis encompasses a variety of techniques and methods used to analyze data sets. It plays a vital role in understanding trends, patterns, and relationships within data. The following are key components of statistical analysis:
- Descriptive Statistics: Summarizes and describes the characteristics of a data set.
- Inferential Statistics: Makes inferences and predictions about a population based on a sample.
- Predictive Analytics: Uses statistical algorithms and machine learning techniques to identify the likelihood of future outcomes.
- Prescriptive Analytics: Recommends actions based on data analysis.
Importance of Statistical Analysis in Business Operations
In the context of business operations, statistical analysis serves several critical functions:
- Decision-Making: Provides data-driven insights that support strategic decisions.
