Using NonExperimental Research

Question 1

Behavioral Categories/Checklists

Answer 1

Global or specific behaviors?
Frequency method- how often something happens?
Duration method- how long something happens?
Sampling
Time sampling- observe for set time period; record for set time period
Individual sampling- observe object #1 for set time period; observe object #2 for set time period
Event sampling- record frequency of one specific behavior over set time period

Question 2

Reliability in Observations

Answer 2

Have more than one observer- increases chances you’ll catch everything
But, observers might disagree
Interrater Reliability
Percentage of time observers agree
> 70% is considered okay; > 90% is excellent
