QUESTIONS AND CORRECT SOLUTIONS –
PEREGRINE.
Sampling Error - Correct Answer-The Difference Between The
Results Of Random Samples Taken At The Same Time
Non-Sampling Error - Correct Answer-Occurs When The Sample
Data Are Incorrectly Collected, Recorded, Or Analyzed. Three
Types Of Errors: Data Acquisition Errors, Non-Response Errors
(Or Bias), Selection Bias
Design Of A Good Survey Components - Correct Answer-Short
Survey, Short/Simple Questions, Start With Demographic
Questions, Ues Dichtomous (Yes-No) And Multiple Choice
Direct Observation - Correct Answer-Example: Counts Backpacks
On Campus For A Day
