Document Summary
Causation, units, and time are key elements in planning a research study. Chapter 4: general issues in research design: often, cj researchers want to find out something that involves questions of cause and effect. Necessary and sufficient causes: a necessary cause is a condition that must be present for the effect to follow, a sufficient clause, in contrast, is a condition that more or less guarantees the effect in question. Instead, social scientists try to address different validity threats in casual interference- reasons we might be incorrect in stating that some cause produced some effect. Example of issue in external validity: external validity is concerned w/ whether research findings from one study can be reproduced in another study, often under different conditions. Construct validity: this type of validity is concerned w/ how well an observed relationship b/w variables that a researcher has measured represents the underlying casual process of interest.
