Understanding Data

Data analysis questions involve interpreting charts, tables, and graphs. You'll need to extract relevant information, perform calculations, and recognize trends or patterns.

Core Concepts

  • Mean, median, mode, and range
  • Interpreting bar graphs, line graphs, pie charts, and tables
  • Probability basics

Everyday Use

Data analysis is useful for understanding statistics in news articles, sports scores, and business reports.

Tips

  • Always check units and labels on graphs.
  • Look for patterns or outliers in the data.

Examples

  • A table shows the sales of 5 products. The mean sales are calculated by adding all sales and dividing by 5.

  • A pie chart shows 30% of students prefer math, and 70% prefer reading. Out of 200 students, 60 prefer math.
