Virginia SOL 2.PS.1

Apply the data cycle to pose questions, collect data, organize and represent data, and analyze data with a focus on pictographs and bar graphs.

What students need to be able to do

  • Pose questions, given a predetermined context, that require the collection of data (limited to 25 or fewer data points for no more than six categories).
  • Determine the data needed to answer a posed question and collect the data using various methods (e.g., voting, lists, tables, charts, tallying).
  • Organize and represent a data set using a pictograph where each symbol represents up to 2 data points. Determine and use a key to assist in the analysis.
  • Organize and represent a data set using a bar graph with a title and labeled axes (limited to 25 or fewer data points for up to six categories).
  • Analyze data represented in pictographs and bar graphs and communicate results by asking and answering questions about the data.
  • Draw conclusions about the data and make predictions based on the data represented in pictographs and bar graphs.
