PS295 Lecture Notes - Lecture 5: Standard Scale, Operational Definition, Asteroid Family
Document Summary
Operationalize your variables operational definition define variables conceptually( dictionary definition) and operationally ( how do you measure the variable) operation definition is the methods on how you measure and manipulate the variable ( this varies form researcher, and diff. Working example: as food consumption decrease, activity increases independent variable: food restriction dependent variable: wheel running. Hypothesis: as food restriction increase, wheel running decrease food restriciton and wheel running as operational definitions wheel running--> amount of wheel revolution in a 12 hr time period. Level 1 reduce food intake from 25g to 20g ( low) Specific or precise conclusions precisely where researches may choose to include more levels and more conditions on the iv the strongest effects is moderate level of food restriction has the highest level of activity. Participant availability \24 rats in the lab only 2 levels: 12 rats in each condition (high,low) 6 levels:4 in each condition ( extremely high, high, moderate, low, control)
