Introduction• Do children of abuse become abusers• A look at family history of abuse• Previous studies shows a correlation
Effects of Abuse• Long-term physical, emotional, and psychological effects• Victims are 74% more likely to abuse• Of all victims, 81% of those who abuse as an adult are male• 40% of sexual abusers were sexually abused as a child
Unprovoked Abusers• A small population who abuse without ever experiencing abuse• Some abusers witnesses violence and identify with abuse as a norm• Sources of perceived violence stem from multiple sources
Hypothesis Testing• Step 1: Restate the Question as a Research Hypothesis and a Null Hypothesis about the Populations • Population 1: Abusive home led to violent behavior toward children as adults. • Population 2: The general population (those who abused children as adults without any trace of precursor).
Hypothesis Testing• Step 2: Determine the Characteristics of the Comparison Distribution • Children who grow up in an abusive home are 79% more likely to abuse. Mean while 74% will commit crime, 40% will sexual abuse, and abused males are 81% more likely to hit. • Compare to unprovoked abusers 23 out 1,000 of the population = 2.3% are abusers with 5% witness violence from an environment.
Hypothesis Testing• Step 3: Determine the Cutoff Sample Score on the Comparison Distribution at Which the Null Hypothesis Should Be Rejected • to determine the cutoff score and use the comparison distribution to reject the null hypothesis if the result were extreme
Hypothesis Testing• Step 4: Determine the sample’s score on the comparison distribution. • A sample score would be determined to make comparison distribution between the two populations.• Step 5: Decide Whether to Reject the Null Hypothesis • Decision made based on the Z score and the cutoff score whether a null hypothesis is rejected.
Rejecting the Theory• 79% of abused children will become abusive as adults• 30% of abused children will not abuse• Predetermined Alpha score of 5• The null hypothesis is not rejected based on research data
Conclusion• Statistical evidence• likelihood of becoming an abuser• Cannot be stated as a fact
