Get ready to challenge yourself with questions that include:
- Identifying threats to internal validity
- Understanding the significance of hypotheses
- Exploring different experimental designs
Children recently enrolled at a nursery school are having trouble adjusting. The head teacher designs a story telling program to help them adjust. Four weeks later, observations are made and the children are better adjusted than they were before the program began. A potential threat to internal validity is:
Instrumentation Threat
Testing Threat
Maturation
Regression to the Mean
Manipulation in experiment means ...?
Change something purposefully in the experiment
Replace something by something else
If I want to study the physical growth in teenagers, which type of experimental design should I choose?
Quasi experimental design
Repeated measures design
Time series design
A math test is given to incoming first-year college students. Those scoring the lowest are selected for a 1-week math enrichment program. Following participation, students are tested again and their scores have improved. Credit for this change is given to the program. A potential threat to interval validity is:
Instrumentation Threat
Regression to the Mean
Selection by Maturation
History Threats
External validity is the extent to which _____.
The results of a study can be generalized to the world at large
The effects of a treatment only last a short time
Anything different makes a difference
The treatment only works in conjunction with the test
In internal validity, a researcher wants to say that only the _____ caused the change in the _____.
Testing; dependent variable
Independent variable; dependent variable
Dependent variable; independent variable
Internal traits; independent variable
Maturation is :
Selecting individuals for a group based on extreme scores.
Biological or psychological changes that may occur simply due to the passing of time are.
Loss of participants due to non random reasons is known
Threats to the validity of a study are factors that make it impossible to have confidence in the study findings.
True
False
A Quasi Experiment Is generally used to:
Investigaterelationships between variables without the researcher controlling or manipulating any of them.
To Demonstrate A Causal Relationship
Get a deep understanding of people, their activities, environment and cultures.
The interrupted time series design involves:
Making an observation immediately before and immediately after a treatment is instituted.
Using time as the independent variable.
Making observations over an extended period of time before and after a treatment is instituted.
Comparing treatment and control groups over an extended period of time.
Which of these contains steps of conducting an experimental research in the right order?
Ask a question, form hypotheses, conduct experiment, analyse data, make conclusion
Ask question, form hypotheses, identify participants, analyze data, make conclusion
Form hypotheses, choose a type of experimental design, conduct experiment, make conclusion
Ask question, form hypotheses, identify participants, select experimental treatment, choose a type of experimental, conduct experiment, analysis of data, report
We use outcome measures to assess:
Negative effect of intervention
Positive effect of intervention
Both pf them
An extraneous variable is any variable that you’re not investigating but it can potentially affect the:
Independent variable
Natural characteristic
Dependent variable
A pretest–posttest design is used to compare the change that occurs on dependent variables by measuring it at two time periods, before and after introducing the independent variable
True
False
People in a homogeneous sample do not share the same age, gender, academic grade, personal abilities
True
False
Which of the following is not a characteristic of a good experiment
The experiment has a powerful intervention.
The researcher uses measures and observations that are valid, reliable, and sensitive.
The researcher addresses threats to internal and external validity
The researcher does not control the extraneous variables
