Select
one of the following scenarios based on your particular field of interest in
psychology:

·
Industrial/Organizational
Psychology:

o
A few months ago, the upper management
at a large corporation decided they wanted to make major changes in the
organization. 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:

o
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:

o
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.
