Field Study Questions Investigates a relationship between an independent and a dependent variable

DRY MIX If you get confused about the terms… DRY – Dependent and Responding Variable are the same – Always go on the Y-axis of a graph MIX – Manipulated and Independent Variable are the same – Always go on the X-axis of a graph

…..a well-written PROCEDURE for a FIELD STUDY Includes logical steps to do the field study Identifies the Independent Variable and the 3 conditions to be compared Identifies the Dependent Variable and the data to be collected Describes the method for collecting data (with what tool) and indicates how often data should be collected and recorded Mentions the environmental conditions to be recorded

NEXT STEPS: Review the field study question you submitted yesterday. Re-write question if necessary Identify the independent variable and the 3 conditions Identify the dependent variable and the measuring tool Write a well-written PROCEDURE that reflects your well-written field study question
