Problem Set 2: The independent-samples t
test
Research Scenario: A forensic psychologist has
developed a new program that teaches empathy and positive social
skills to youth offenders who are incarcerated for a violent
offense. She wants to know whether this new treatment is more
effective in increasing empathy than the standard
treatment that these youth offenders usually receive. She sets up a
treatment group that consists of 8 youth offenders incarcerated for
violent offenses who will receive the new treatment....

Assignment #3: Independent Samples T test Conduct an Independent
Samples T test to answer the questions based on the following
scenario. (Assume a non-directional research hypothesis (two-tailed
test) and a level of significance of .05) The superintendent who
collected data for Assignments 1 and 2, continued to examine the
district’s data. One question that concerned the superintendent’s
constituencies was the difference between the school performance
scores of the superintendent’s district and a neighboring district
that had similar demographic and socio-economic...
