  1. Collecting & Displaying Data

  2. Data Tables • Numerical (quantitative) data organized in rows and columns • The specific independent variables are listed • The number of trials are listed • Blanks are left for the data (dependent variable) to be filled in

  3. Title Describing the Data

  4. Analyzing the data • Reduce the data • Do something to make the amount of data smaller • Central tendencies • Mean (average) • Median • Mode • Range • frequency

  5. Analyzing the data • Graph the data • Lets us see trends, patterns, relationships, comparisons • Bar graphs • Let us compare data • Line graphs • Lets us see trends or changes

  6. Bar graph This shows a comparison of types and amount of trash on a beach.

  7. Line graph This shows how the grade point average has been changing over several years. The trend is an increase in GPA.

  8. Scatter plotPositive Correlation An increase in the variable on the X-axis is associated with an increase in the variable on the Y-axis
