  1. 1. Dealing with Data<br />
  2. 2. Observation <br />Natural<br />Experimental<br />
  3. 3. Variables<br />Qualitative <br />Attributes<br />Rankable<br />Quantitative<br />Discreet<br />Continuous<br />
  4. 4. Relationship between variables<br />Independence/dependence<br />Readings of two variables are obtained to determine their relationship.<br />Independent variable is under the control of the experimenter. <br />Frequency of distribution<br />Number of observations falling within particular categories. <br />
  5. 5. Tables:Primary Organization of Data<br />
  6. 6. Replicates<br />
  7. 7. GraphsSecondary Organization of Data<br />Bar Graph: Data is discreet.<br />Line Graph: Data is continuous.<br />Scatter Plot: Points are not connected, but a “best of fit” curve is used to express a trend.<br />
  8. 8. Bar Graphs<br />Label<br />
