data and graphs on compressive strength of concrete

  • how does a graph help people interpret scientific data?

    graphs of various types provide convenient visual representations of scientific data that would otherwise be presented in intimidating blocks of text or a series of numbers. graphs represent statistics such as changes over time, comparisons, or parts of a whole. graphs can be used to make date more accessible to both scientists and laypersons.read more≫
