Dimension 1: Practices

Analyzing and interpreting data

Scientific investigations produce data that must be analyzed in order to derive meaning. Because data patterns and trends are not always obvious, scientists use a range of tools—including tabulation, graphical interpretation, visualization, and statistical analysis—to identify the significant features and patterns in the data. Scientists identify sources of error in the investigations and calculate the degree of certainty in the results. Modern technology makes the collection of large data sets much easier, providing secondary sources for analysis.

Science
Data analysis is a crucial step in scientific investigations as it helps derive meaning from the collected data. Since data typically does not convey its message on its own, scientists employ various tools such as tabulation, visualization, and statistical analysis to identify significant features and patterns. Additionally, sources of error are identified and the degree of certainty is calculated. With advancements in technology, collecting large data sets has become more accessible, providing ample secondary sources for analysis.
Engineering
Engineers utilize data acquired from tests and investigations to thoroughly analyze their designs. Through this analysis, they are able to assess and compare various solutions, ultimately determining which design most effectively addresses the problem within the given constraints. Similar to scientists, engineers rely on an assortment of tools to identify significant patterns and interpret the findings.

The Next Generation Science Standards (NGSS) recognize and emphasize the importance of three main dimensions for learning science. These dimensions are essential components in forming each standard—or performance expectation. When taken together, they allow students a chance to gain a more cohesive understanding of science concepts as they progress through their courses.
