Presentation Transcript

  1. GRAPHING

  2. Y axis X axis

  3. IV vs. DV Independent variable (IV): Manipulated variable Ex: speed Dependent variable (DV): Relies on the manipulated variable Ex: time

  4. DRY MIX Dependentvariable Relieson manipulated Y axis Manipulated variable Independentvariable X axis

  5. Title DV 70 DV vs. IV 60 50 DV (with units) 40 SCALE LABELS 30 20 10 IV 1st 2nd 3rd IV (with units)

  6. TYPES OF GRAPHS • Scatter plot: we use this 95% of the time (best fit line) • Line graph: shows changes over time or space • Bar graph: compares different variables • Pie graph: useful with percentages

  7. Speed of A Car TIME (s) DISTANCE (m)

  8. Volume vs. Temp. TEMP ( OC) VOLUME (mL)

  9. KI SOLUBILITY GRAMS DISSOLVED TEMP ( OC)

  10. Abundance of Elements in the Lithosphere Elements %

  11. Interpolate vs. Extrapolate • Interpolate: being able to “construct” data points from inside a known data set • Extrapolate: being able to “construct” data points from outside a known data set (predict)

  12. Interpolate: Distance at time 2.5 s = Extrapolate: Time at Distance 15 m = 5m 9 s X s 6 s = 15 m 10m X s = 0.6 15 m

  13. Create the data table! • For the next slides you will create a data table representing the given graph • Be sure to label IV and DV!

  14. Frozen Dessert Production Frozen dessert Gallon (mil)

  15. USE THE DATA AT THE RED DOTS Individual Water Use from 1983-2001 Water Use (Liters per person) Municipal Water Use Per Person from 1983-2001 Year L / person

  16. Sources of Radiation Exposure sources %
