She asks for volunteers from her third period class to report the number of nightmares they had last week. Clearly describe four things wrong with the design of this study.

Answers

Answer 1
1 point: There is no hypothesis stated. 1 point: In asking for volunteers, the teacher is taking a nonrandom sample that is probably not representative of the population of interest. 1 point: Neither dreams nor nightmares are operationally defined, so they might be interpreted differently by later researchers. 1 point: The research is not blind. The teacher could influence the results by the way he asked questions. (choose 2)

Answer 2

According to the question, Dreams and nightmares are not operationally defined, so future studies may interpret them differently. The study is open-minded. Through his questioning techniques, the teacher had a say in the outcomes.

What are Nightmares?

One of the most complex and enigmatic components of sleep is dreaming. Dreams can be grandiose and blissful, but they can also be frightful, dangerous, or stressful.

Nightmares are frightening, disturbing, strange, or otherwise bothersome dreams that are extremely vivid. Rapid eye movement (REM) sleep, the phase of sleep linked to vivid dreaming, is when they happen more frequently.

When greater time is spent in REM sleep in the second half of the night, nightmares occur more frequently. It's common to be intensely aware of what occurred in the dream when you wake up from a nightmare, and many people have feelings of angst or anxiety as a result.

Several complaints related to the officers' failure to follow up on requests for medical care. There was also one complaint regarding lost mail. Your investigation leads you to believe that these issues were not intentional on the part of the officers; nevertheless, they still get classified as:

Answers

The complaints will still be classified as Negligent Abuse.

Since the correctional officers received on-boarding training and began work together, the investigation report of the inmate complaints against the officers will be classified as negligent abuse.

Based on the investigations, the officers have failed to meet the inmates' basic needs, they may need further training because negligent abuse is a serious offense when left to continue. If, after their additional training, they persist with their attitude, it may be time to relieve them of the responsibility and consider them unfit to attend to the state prison inmates.

Thus, while the issues of complaint might not be intentional on the part of the correctional officers, it seems that their initial training was inadequate.
