  1. Chemistry: Matter and Change Chapter 2 Analyzing Data

  2. Chemistry: Matter and Change Section 2.4 Representing Data

  3. Chemistry: Matter and Change Objectives Create graphics to reveal patterns in data. Review Vocabulary independent variable: the variable that is changed during an experiment Interpret graphs. New Vocabulary graph

  4. Chemistry: Matter and Change Graphs visually depict data, making them easier to see patterns and trends.

  5. Graphing Chemistry: Matter and Change A graphis a visual display of data that makes trends easier to see than in a table.

  6. Graphing Chemistry: Matter and Change A circle graph, or pie chart, has wedges that visually represent percentages of a fixed whole.

  7. Graphing Chemistry: Matter and Change A bar graph, or barph (I made that up), is used to show how a quantity varies across categories.

  8. Graphing Chemistry: Matter and Change On line graphs, independent variables are plotted on the x-axis and dependent variables are plotted on the y-axis.

  9. y2 – y1 x2 – x1 rise run Δy Δx slope = = = Graphing Chemistry: Matter and Change If a line through the points is straight, the relationship is linear and can be analyzed further by examining the slope.

  10. Interpreting Graphs Chemistry: Matter and Change Interpolation is reading and estimating values falling between points on the graph.

  11. Interpreting Graphs Chemistry: Matter and Change Extrapolation is estimating values outside the points by extending the line.

  12. Chemistry: Matter and Change Assessment _____ variables are plotted on the ____-axis in a line graph. • independent, x • independent, y • dependent, x • dependent, y

  13. Chemistry: Matter and Change Assessment _____ variables are plotted on the ____-axis in a line graph. • independent, x • independent, y • dependent, x • dependent, z
