55 MPH. Speed limit. Was introduced in the US in 1973. Shortly thereafter, the number of auto accidents declined. We can conclude that.
a. The reduced speed limit caused the decline in auto accidents.
b. The reduced. Speed limit. May have caused the decline in the number of auto accidents.
c. The reduced speed limit had nothing to do with the decline in auto accidents.
b
Quasi. Experimental designs are often used instead of experimental designs because
a. Agency constraints often make experiments infeasible.
b. They have more internal validity than experiments.
c. All of these.
a

b. Solomon Four group design.
c. One shot case study.
c
Pre experimental designs.
a. Are the weakest experimental designs.
b. Control for most sources of internal and validity.
c. Control for most sources of external invalidity.

A school social worker Administered a self esteem test to a group of 9th graders in September. During the school year, the students received intensive social work intervention. Designed to improve their self esteem. In May, the Self Esteem test was given again. And the Self Esteem scores improved. A major problem in this research is that the researcher failed to control for
a. History.
b. Selection biases.
c. Testing.
d. All of these.

d. it provides a mean for studying a large variation in the pop….
b
The problem of external validity refers to the generalizability Of results. True or false?
t
The length of the baseline in single case designs should be
a. As long as. Is practically and ethically possible.
b. Longer with a few. Low frequency behavior than with a high frequency behavior.
c. All of these.
d. extended until a stable trend appears
c
In deciding What to measure in a single case experiment, It is usually best to.
a. Pick something implied by how the clinical goal was operationally defined.
b. Measure more than one thing.

b. Have cottage parents run spot checks in the cottage at different intervals.
c. Shop up at the Cottage and Absorb. The child yourself for one hour during the same. Each day.
b
What is the most appropriate Inference for future. Interventions with similar clients?
a. Just provide the family education.
b. Provide all three interventions in the same order
c. Replicate the study to assess possible order effects.
d. None of these.
c
In a single case, design with a student at high risk for dropping out of school, A good measurement plan to assess whether our intervention is effective would be to monitor whether or not he/She drops out of school. True or false?
false
