Directions: Respond to the prompts following each of the scenarios below based on the module readings and any other resources you find helpful.  Each response should be 75 to 100 words.

 

Scenario 1: Jeannine and Robert have been together for five years and have been married for the past three years. They live in an apartment together. There have been a few instances of physical violence from Robert toward Jeannine throughout the relationship, mostly shoving her around and, a couple of times, slapping her, always followed by effusive apology, explaining his actions as stress from his job.  Imagine you are Jeannine’s counselor and she reveals that Robert has been showing signs of more violence, escalating in verbal threats. A couple of weeks ago, he grabbed her by the shoulders and shook her so violently, she ended up with a sore neck and migraine headache. Last week, he punched her in the ribs a couple of times, resulting in bruising, which she revealed to you. She fears for her safety, though she is not yet ready to move out or leave him.

1.Describe Jeannine’s level of lethality:

 

2.Devise a safety plan for Jeannine :

 

3.Explain why you devised the safety plan the way you did:

 

Scenario 2: Maria states she met Justin at a party a couple months ago. They have gone out a few times. Justin has never been to Maria’s house but she has been to his apartment; client states she usually meets him at a restaurant or club. Maria tells you that the other night, while out with Justin, he became “physically aggressive.” She reports that she woke the next morning at her home with a lack of memory from the night prior. She tells you that she was too ashamed to report it to the police and she wasn’t sure what happened. Imagine you are Maria’s counselor and she reveals to you that yesterday Justin became abusive and threatening toward her after she refused his sexual advances. Justin threatened that he would break off their relationship and find someone “more mature” in her attitude toward sex. She is afraid that he will follow through on his threats to break off their relationship. You know from past visits that, although attractive and intelligent, she has self-esteem problems.

 

1.Describe Maria’s level of lethality.

 

2.Devise a safety plan for Maria:

 

3.Explain why you devised the safety plan the way you did:

 

Scenario 3: Arthur and Melissa have been married for seven years but have been separated for the past year. The couple has two small children. They share custody. Imagine Arthur is your client, and, during a session, Arthur reveals that Melissa has recently become physically violent with him, slapping and punching him, but he has been too embarrassed to disclose the abuse. Client states that his wife has never acted this way before and he is afraid that the children may not be safe when left alone with her. Client states he is unsure about how to protect himself and, more so, his children.

Time to Practice – Week Four

 

Complete Parts A, B, and C below.

 

Part A

 

Some questions in Part A require that you access data from Statistics for People Who (Think They) Hate Statistics.This data is available on the student website under the Student Text Resources link.

 

1.     Using the data in the file named Ch. 11 Data Set 2, test the research hypothesis at the .05 level of significance that boys raise their hands in class more often than girls. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one- or two-tailed test.

 

2.     Using the same data set (Ch. 11 Data Set 2), test the research hypothesis at the .01 level of significance that there is a difference between boys and girls in the number of times they raise their hands in class. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? You used the same data for this problem as for Question 1, but you have a differenthypothesis (one is directional and the other is nondirectional). How do the resultsdiffer and why?

 

3.     Practice the following problems byhand just to see if you can get the numbersright. Using the following information, calculate the ttest statistic.

 

a.

b.

c.

 

4.     Using the results you got from Question 3 and a level of significance at .05,what are the two-tailed critical values associated with each? Would the nullhypothesis be rejected?

 

5.     Using the data in the file named Ch. 11 Data Set 3, test the null hypothesis that urban and rural residents both have the same attitude toward gun control. UseIBM®SPSS®software to complete the analysis for this problem.

 

6.     A public health researcher tested the hypothesis that providing new car buyers with child safety seats will also act as an incentive for parents to take other measures to protect their children (such as driving more safely, child-proofing the home, and so on). Dr. L counted all the occurrences of safe behaviors in the cars and homes of the parents who accepted the seats versus those who did not. The findings:a significant difference at the.013 level. Another researcher did exactly the same study; everything was the same—same type of sample, same outcomemeasures, same car seats, and so on. Dr. R’s results were marginally significant(recallCh. 9) at the .051 level. Whichresult do you trustmore and why?

 

7.     In the following examples, indicate whether you would perform a t test ofindependent means or dependent means.

 

a.     Two groups were exposed to different treatment levels for ankle sprains.Which treatment was most effective?

b.    A researcher in nursing wanted to know if the recovery of patients was quickerwhen some received additional in-home care whereas when others received thestandard amount.

c.     A group of adolescent boys was offered interpersonal skills counseling andthen tested in September and May to see if there was any impact on familyharmony.

d.    One group of adult men was given instructions in reducing their high bloodpressure whereas another was not given any instructions.

e.     One group of men was provided access to an exercise program and tested twotimes over a 6-month period for heart health.

 

8.     For Ch. 12 Data Set 3, compute the t value and write a conclusion on whether there is a difference in satisfaction level in a group of families’ use of service centers following a social service intervention on a scale from 1 to 15. Do this exercise using IBM®SPSS®software, and report the exact probability of the outcome.

 

9.     Do this exercise by hand. A famous brand-name manufacturer wants to know whether people prefer Nibbles or Wribbles. They sample each type of cracker and indicate their like or dislike on a scale from 1 to 10. Which do they like the most?

11.  Using the data in Ch. 13 Data Set 2 and the IBM®SPSS®software, compute the F ratio for a comparisonbetween the three levels representing the average amount of time thatswimmers practice weekly (<15, 15–25, and >25 hours) with the outcome variablebeing their time for the 100-yard freestyle. Does practicetime make a difference?Use the Options feature to obtainthe meansfor the groups.

 

12.  When would you use a factorial ANOVA rather than a simple ANOVA to test thesignificance of the difference between the averages of two or more groups?

 

13.  Create a drawing or plan for a 2 × 3 experimental design that would lend itself toa factorial ANOVA. Identify the independent and dependent variables.

Part B

Some questions in Part B require that you access data from Using SPSS for Windows and Macintosh. This data is available on the student website under the Student Text Resources link.

 

The data for Exercise 14 is in thedata file named Lesson 22 Exercise File 1.

 

14.  John is interested in determining if a new teaching method, the involvement technique, iseffective in teaching algebra to first graders. John randomly samples six first graders from allfirst graders within the Lawrence City School System and individually teaches them algebra withthe new method. Next, the pupils complete an eight-item algebra test. Each item describes aproblem and presents four possible answers to the problem. The scores on each item are 1 or 0,where 1 indicates a correct response and 0 indicates a wrong response. The IBM®SPSS® data file containssix cases, each with eight item scores for the algebra test.

Discussed how effective Viagra woud be for improving James’ sex life, and why.

Sexual Disconnect

James and Yelena have been married for 22 years and have three grown children, now out of the house. Sex was never particularly enjoyable for Yelena, primarily because James was uninterested in much foreplay and Yelena felt it was unfeminine to make any sexual demands of her husband. However, because of her love for James, she accommodated his desire for sex two or three times a week, and consistently “faked orgasms.”

James also does not think “a real man” should receive any “help” from his wife to get an erection, even when his erections became less firm and less predictable. As a result, over the last two years, James rarely initiated sex and Yelena felt relieved, thinking she would now be “excused from sex.” Furthermore, she is in perimenopause, and has begun to experience increasingly uncomfortable penetration. Suddenly, James’ vigor and sexual interest has returned with greater intensity than ever. Yelena discovered he was secretly taking Viagra, which he obtained over the Internet.

    • Discuss how effective you think Viagra will be for improving James’ sex life, and why?
    • Suppose Yelena’s discovery that James is using Viagra secretly is the “last straw” for her after years of not addressing her unsatisfying sexual life with him, and she demands that they seek marriage counseling and focus on their sex life.

      In this case:

      • What part of this dilemma should a counselor point out is Yelena’s responsibility to acknowledge and address? Additionally, what special issues regarding her perimenopause will need to be addressed?
      • What part of this dilemma should a counselor point out is James’ responsibility to acknowledge and address?

 

  • Discuss specific treatment options for this couple that are supported by the research you learned about in your readings.

Submit your response to the M2: Assignment 2 Dropbox by Wednesday, February 24, 2016. Your response should be at least 3 pages long, not counting the cover page and reference page.

Reinforcement Procedures

/in /by

Consider the following scenario:

 

A mom is trying to increase the amount of peas that her two children eat. She uses a sticker chart to monitor the amount of peas they are consuming and rewards them based on the number of stickers they have at the end of the week. The mom has found that this works for one child, but not the other.

 

Write a 350- 500 -word paper discussing the following:

 

  • Identify the behavior that the mom is trying to reinforce.
  • Identify the method of reinforcement being used.
  • Explain possible reasons for this method working for one child and not the other.
  • Propose and outline three ideas that may work to increase pea consumption for the children, and include one method that uses negative reinforcement.

 

Format your paper consistent with APA guidelines.
