  3. 3. Description of 702. <ul><li>This course presents classic research methods and considers experimental biases which affect them. </li></ul><ul><ul><li>Sixteen research design situations illustrate research control factors, and . . . </li></ul></ul><ul><ul><li>Twelve internal and external biases distort elements of research. </li></ul></ul>
  4. 4. Rationale. <ul><li>Constructing good research proposals requires understanding basic designs and how they are affected. </li></ul><ul><ul><li>Internal biases of history, maturation, testing, instrumentation, regression, selection and mortality. </li></ul></ul><ul><ul><li>Combined effects of biases. </li></ul></ul>
  5. 5. Objectives. <ul><li>After this course, the student will. . . </li></ul><ul><ul><li>Select several classic experimental research designs and compare the biases affecting them. </li></ul></ul><ul><ul><li>Considering his own topic, briefly sketch the biases affecting it. </li></ul></ul><ul><ul><li>Discuss control of biases affecting his own topic. </li></ul></ul>
