The US Department of Justice is concerned about the negative consequences of dangerous restraint techniques being used
Question:
The US Department of Justice is concerned about the negative consequences of dangerous restraint techniques being used by the police. They hire a researcher to collect a random sample of police academies and to analyze the extent the type of dangerous restraint training in their curriculums has an impact on different types of negative consequences in those police academy’s respected jurisdictions. See ANOVA table below.
Dangerous Restraint Technique Training by Type of Negative Consequences
Type of Negative Consequences | Dangerous Restraint Technique Training is: | F-Ratio | P-value (significance) | ||
Not Required | Covered | Stressed | |||
Number of deaths | 1200 | 905 | 603 | 5.05 | .054 |
Number of lawsuits | 204 | 155 | 95 | 8.12 | .032 |
Number of injuries | 160 | 80 | 35 | 12.05 | .003 |
Number of citizen complaints | 15 | 13 | 4 | 16.43 | .001 |
Answer and explain the following questions (assume alpha is .05):
1. The Type of Dangerous Restraint Technique Training has a statistically significant impact on which negative consequence(s)? Explain.
2. The Type of Dangerous Restraint Technique Training does not have a statistically significant impact on which negative consequence(s)? Explain.
3. The Type of Dangerous Restraint Technique Training has its most statistically significant impact on which negative consequence? Explain.
4. Given what you have learned about the limitations of ANOVA, do you have any potential concerns about the data in the table? Hint: Look closely. If so, please name and discuss the extent of your concerns.
