Data Analysis, Statistics, and Probability

Data analysis, statistics, and probability comprise about 20%-30% of the questions on the GED Math Test. This includes such things as:

  • Constructing, interpreting, and drawing inferences from tables, charts, graphs, and statistical data.
  • Comparing and contrasting, making predictions, and solving problems using data.
  • Understanding data sampling and bias.
  • Making predictions based on probability.
  • Computing and applying measures of central tendency such as mean (average), median, and mode.

Approximately 50% of the questions on the GED Math Test use some type of graphic-based material. Students need to understand that information is often provided in different forms. Constructing, interpreting, and inferring information from tables, charts, and graphs requires that students possess problem-solving strategies that deal with models, diagrams, tables, charts, and lists.
