Illustrating the Process of Statistics
✔Step 1: Identify the research objective.
To determine whether males accused of battering their intimate female partners that were
assigned into a 40-hour batter treatment program are less likely to batter again compared to those
assigned to 40-hours of community service.
Step 2: Collect the information needed to answer the question.
The researchers randomly divided the subjects into two groups. Group 1 participants received the
40-hour batterer program, while group 2 participants received 40 hours of community service.
Six months after the program ended, the percentage of males that battered their intimate female
partner was determined.
Step 3: Describe the data - Organize and summarize the information.
The demographic characteristics of the subjects in the experimental and control group were
similar. After the six month treatment, 21% of the males in the control group had any further
battering incidents, while 10% of the males in the treatment group had any further battering
incidents
Step 4: Draw conclusions from the data.
