• What is the purpose of data presentation in statistics?

  To organize and display data
• Data interpretation is the process of analyzing data presentations to identify patterns, trends, and relationships
• Data presentation aims to organize and display data clearly, while data interpretation focuses on analyzing data and drawing conclusions.
• Match the statistical concept with its example:
