HED 373 Exam1 Questions and Answers
empirical approach - Answer-based on observations
experimental research - Answer-treatments are given for the research purpose
example: treating some students with hands-on manipulatives and others with a workbook approach to
determine which treatment causes greater math achievement
nonexperimental research - Answer--no treatment is given, obseravation is used to describe
participants as they naturally exist
example: asking teachers about their needs without giving treatments
types: polls, surveys
experiments - Answer-researchers give treatments and observe if they cause changes in behavior
true experiment - Answer-when participants are divided at random
causal-comparative study (ex post facto study) - Answer--researchers observe and describe some
current condition
-researchers look to the past to try to identify the possible causes of the condition
-NO treatment/NONEXPERIMENTAL
, -used when researchers are interested in causality, but it is not possible to conduct an experiment
survey/poll - Answer--used to describe the attitudes. beliefs, and behaviors of a population
-researchers draw a sample of a population, study the sample, then make inferences to the population
from the sample data
census - Answer--researcher interviews everyone in the population
-count or study of all members of a population
longitudinal research - Answer-researchers repeatedly measure traits of the participants over a period
of time in order to trace developmental trends
-NONEXPERIMENTAL
case study - Answer-usually involves one participants, the emphasis is on obtaining thorough
knowledge of an individal-sometimes over a long period of time
-NONEXPERIMENTAL
correlational research - Answer-researchers are interested in the degree of relationship among two or
more quantitative variables
example: researcher conducts a study where he asks "Did those with high admissions scores tend to
earn higher GPAs?"
-NONEXPERIMENTAL
quantitative research - Answer-data are easy to quantify and allows for statistical analysis
qualitative research - Answer-researchers gather data that must be analyzed through the use of
informed judgment to identify major and minor themes expressed by participants
