PrecisePrecise

To make hypotheses more precise, psychologists use To make hypotheses more precise, psychologists use operational definitions to define the variables they operational definitions to define the variables they study. study.

Ex.: Ex.: A psychologist conducts an experiment to find out A psychologist conducts an experiment to find out

whether toddlers are happier in warm weather or cool whether toddlers are happier in warm weather or cool weather. She needs to have an operational definition of weather. She needs to have an operational definition of happiness so that she can measure precisely how happy happiness so that she can measure precisely how happy the toddlers are.

ParsimoniousParsimonious

The principle of parsimony maintains that researchers The principle of parsimony maintains that researchers should apply the simplest explanation possible to any should apply the simplest explanation possible to any set of observations. set of observations.

Example: Example: Suppose a student consistently falls asleep in her statistics Suppose a student consistently falls asleep in her statistics

class. She theorizes that before each class, her statistics class. She theorizes that before each class, her statistics professor secretly sprays her seat with a nerve gas that professor secretly sprays her seat with a nerve gas that makes her very drowsy. If she had applied the principle makes her very drowsy. If she had applied the principle of parsimony, she would not have come up with this of parsimony, she would not have come up with this theory. She can account for her sleepiness with a much theory. She can account for her sleepiness with a much simpler and more likely explanation: she finds statistics simpler and more likely explanation: she finds statistics boring.boring.
