PRESENTING DATA

Organizing Data • Data tables • Table contains 2 variables • Manipulating • Responding Average Annual Precipitation for Selected U. S. Cities City Average Annual Precipitation Buffalo, NY 98. 0 Chicago, Il 91. 0 Colorado Springs, CO 41. 2 Houston, TX 117. 0 San Diego, CA 25. 1 Tallahassee, FL 166. 9 Tucson, AZ 30. 5

Line Graphs • Manipulating variable found on x-axis • Responding variable found on y-axis • Slope- vertical change of line • Slope = rise/run • Direct proportion- relationship in which the ratio of the manipulating and responding variables are constant • Inverse proportion- product of the manipulating and responding variables is a constant

Slope

Line Graphs (cont. ) • Direct proportion example • 3 cm 3 of water has a mass of 3 grams. Doubling volume will double the mass • Inverse proportion example • A flow rate of 0. 5 gallons per minute will fill the pot in 2 minutes. If you double the flow rate you will reduce the time required to fill the pot by half.

Bar Graphs • Compare a set of measurements, amounts, or changes. Average Annual Precipitation for Select U. S. Cities Tucson Tallahassee San Diego Average Annual Precipitation for Select U. S. Cities Houston Colorado Springs Chicage Buffalo 0 100 200
