1. Understanding data and data representations
Data is information collected through observation, measurement, surveys, experiments, or other methods. It can be qualitative (descriptive, non-numerical) or quantitative (numerical). In mathematics, especially in problem-solving situations , interpreting data means understanding how the data is organized and displayed, then using it to answer questions or make decisions.
Data representations are methods of organizing and displaying data so patterns, trends, and relationships are easier to identify. These include tables, various types of graphs, and specialized diagrams. Choosing the correct representation often depends on the type of data and the goal of the analysis.
