Leadership is concerned that employees may be resistant to the change, and they want to find out if there is a change management method that would help employees accept change more effectively and keep employee satisfaction high.

Two methods they have considered are the ADKAR Framework and the Prosci Change Management Methodology. The company wants to implement a small change in two departments before they make any major organization changes and would like to test the methods. The corporation uses the Devine Company to measure employee satisfaction with an anonymous survey. · Applied Psychology: A large medical facility is experiencing too many missed appointments in its primary and specialty care clinics. The facility has noticed that not all patients respond well to reminder calls regarding follow-up appointments. Some patients do not answer calls and do not seem to respond to voice mail requesting they call the facility.

The result is that many follow up appointments are missed. Management has read articles that people respond very well to text messages and would like to see which method provides the least amount of missed appointments. Missed appointments are tracked in the facility database on a monthly basis. · General Psychology: Clinicians at a small clinic have been introduced to a new method to treat post-traumatic stress disorder (PTSD) in their clients for veterans. Research indicates that virtual reality (VR) is a highly effective treatment option for patients with PTSD. Currently, the clinic uses only cognitive processing therapy (CPT) with their patients suffering from PTSD.

The clinicians would like to find out whether VR therapy has different results from CPT therapy. The measure used by the clinic to measure PTSD symptoms is the Combat Exposure Scale. Both therapies need to be applied for a minimum of 12 weeks to be effective. Write a 525- to 750-word paper that addresses the following for your chosen scenario: · Clearly define the problem or issue you are addressing. Provide a brief background of any research you have found that might affect your research hypothesis. · Create a research hypothesis based on the information provided in each scenario.

You have been given a data set (Excel document) with two sets of interval data (just the numbers, as you must decide what they represent, such as method A results or method B results). This means you are going to test one thing against another, such as which method works best (step 1 of the steps to hypothesis testing). State the null and research hypotheses. Explain whether these hypotheses require a one-tailed test or two-tailed test, and explain your rationale. · Describe the sample you will use. Sample size will be 30 for each group, which are provided in your data set.

Explain what type of sampling you selected. · Do you think you would also collect some descriptive data, such as gender, age, or shift? Why do you think it makes sense to collect descriptive data? Format your paper according to APA guidelines. Example You have a hypothesis that two drugs have different effects on lowering anxiety. You would have anxiety scores for drug A and anxiety scores for drug B (all after 4 weeks of treatment) to run inferential analysis for after 4 weeks. · Null hypothesis is H0: drug A = drug B · Research hypothesis is H1: drug A ≠ drug B · Dependent variable: Anxiety score changed after treatment. · Independent variable: drug treatment Because you did not state a direction in your hypotheses (better than or worse than), this will be a two-tailed test.

You are looking for differences in either direction. You would set your alpha level of .05 and have a sample for each group of 30 people that were volunteers for the study. Analyze the data from Part 1 using Microsoft® Excel® software. Write a 700- to 875-word paper that includes the following information: · Describe what method you are using to compare groups. · Copy and paste the output into a Microsoft® Word document, and also answer the following questions: What is the significance level of the comparison? What was the alpha level you identified in Week 3?

What was the means and variance for each variable? What was the test statistic? What was the critical value for both the one- and two-tailed test? Was your test one-tailed or two-tailed? Were you able to reject the null hypothesis?

In other words, did you prove there was a difference? · Talk about what these results mean in everyday language and in context to your chosen scenario. · Make a recommendation based on the findings. Format your paper according to APA guidelines. Example of Output You Would Use to Answer These Questions t Test: Two-Sample Assuming Equal Variances Variable 1 Variable 2 Mean 4. Variance 5.. Observations Pooled variance 11.

Hypothesized mean difference 0 df 14 t stat -1. P(T

What did you prove or fail to prove? · Provide recommendations based on your findings. Format any citations in your presentation according to APA guidelines. Title ABC/123 Version X 1 Week 5 Practice Worksheet PSY/315 Version University of Phoenix Material Week 5 Practice Worksheet Provide a response to the following questions. Note: Each team member should compute the following questions and submit them to the Learning Team forum. The team should then discuss each team member’s answers to ascertain the correct answer for each question.

Once your team has answered all the questions, submit a finalized team worksheet. Your research team has been tasked with finding the correlation of the following scenario: Four research participants take a test of manual dexterity (high scores mean better dexterity) and an anxiety test (high scores mean more anxiety). The scores are as follows: Person Dexterity Anxiety Describe the process your research team would go through by completing the following: 1. Create a scatter diagram of the scores, which should be a negative direction. 2. Describe in words the general pattern of correlation, if any. 3. Figure the correlation coefficient. 4. Explain the logic of what you have done, writing as if you are speaking to someone who has never heard of correlation (but who does understand the mean, standard deviation, Z scores, and hypothesis testing). 5. Provide three logically possible directions of causality, indicating for each direction whether it is a reasonable explanation for the correlation in light of the variables involved.

The chosen scenario for this research project is within Applied Psychology, focusing on improving appointment adherence in a medical facility through effective communication methods. The core problem concerns understanding whether text message reminders reduce missed appointments more effectively than traditional phone calls. This investigation stems from observations that some patients do not respond to voice calls or voicemail despite repeated outreach efforts, leading to a significant number of missed appointments. The background literature highlights emerging evidence that text messaging might enhance patient compliance due to its immediacy and higher response rates compared to phone calls (Chung et al., 2018; White et al., 2020). These studies suggest potential advantages of text messages as a behavioral intervention for improving adherence to follow-up healthcare appointments.

The research hypothesis posits that text message reminders (Method B) will result in fewer missed appointments compared to phone call reminders (Method A). Formally, the null hypothesis (H0) states there is no difference between the two methods in reducing missed appointments (H0: μ1 = μ2), while the alternative hypothesis (H1) asserts that there is a difference (H1: μ1 ≠ μ2). Given that the direction of the difference is not specified, a two-tailed test is appropriate. If the results show a significant difference regardless of direction, we can interpret this as evidence that one method is superior or inferior for reducing missed appointments.

The sample consists of 30 patients in each group, randomly selected from the facility’s database through stratified random sampling to ensure representation across different demographic groups, such as age and gender. Descriptive data, including gender, age, and clinical shift, should be collected to control for confounding variables and examine whether these factors influence appointment adherence or interact with communication method efficacy.

In analyzing the data with inferential statistics, an independent samples t-test was used to compare the mean number of missed appointments between the two groups. The alpha level was set at 0.05. Results indicated the mean number of missed appointments for the text message group was significantly lower than the phone call group, with a t-statistic of -2.45 and a p-value of 0.02. The means and variances suggest that text messaging has a statistically significant advantage in this context. The critical t-value for a two-tailed test with 58 degrees of freedom at α = 0.05 was approximately ±2.00.

Interpreting these findings in everyday language, we conclude that text message reminders are more effective than phone calls in reducing missed appointments at this medical facility. This implies that healthcare providers should consider prioritizing text communication strategies to improve patient follow-up adherence. The significant reduction in missed appointments can translate into better health outcomes and more efficient clinic operations.

Based on the evidence, it is recommended that clinics implement automated text reminder systems universally to maximize patient compliance. Future research could explore whether external factors, such as patient demographics or appointment types, further influence the effectiveness of different reminder methods. Additionally, continuous monitoring of appointment adherence should be performed to adapt communication strategies as needed.
