Topic 1 (200-400 words)
It has long been a requirement for health care workers to take an Introduction to Statistics class. Why is it important for a person working in health care to understand statistical concepts? To answer this question, please provide two specific examples incorporating two different statistical terms from “Visual Learner Statistics,” located in the Topic 1 Resources. Do not use the same examples as those in a prior post. You may reference other articles in this topic or conduct your own scholarly research if more statistical terms are needed.
Topic 2 (200-400 words)
Design an experiment with one independent variable (with at least two levels) and one dependent variable. Additionally, what levels of measurement would you use when collecting your data?
Example: XYZ hospital wanted to increase compliance of staff using hand sanitizer after every interaction with a patient. In order to gain compliance, they set up a buzzer when staff exited the patient’s room. For the treatment group, a buzzer would ring for 1 second after exiting the room unless staff had pressed the hand sanitizer lever. The control group did not have the buzzer activated, so no sound would emit when exiting the patient’s room.
Independent Variable: Presence of a buzzer sound or not.
Dependent Variable: Number of times the hand sanitizer lever was pressed.
Level of Measurement: Ratio
Topic 3 (200-400 words)
Review the terms Stratified Sampling, Cluster Sampling, Random Sampling, and Systematic Sampling from “The Visual Learner: Statistics,” located in the Topic 2 Resources.
For this question you are divided into groups based on your last name. Identify your given sampling method using the first letter of your last name.
- G-L – Cluster Sampling— THIS ONE
Use the assigned sampling method to answer the following question:
Imagine that you are conducting a patient satisfaction survey at your health care facility. How would the assigned sampling method be applied in this case? What are the strengths and weakness of the assigned sampling method in this scenario?
Topic 4 (200-400 words)
Watch three videos (“Measure of Center ‘Mean,'” “Measure of Center ‘Median,'” and “Measure of Center ‘Mode'”) in the Calculations section of “The Visual Learner: Statistics,” located in the Topic 2 Resources.
Go to the Random.org website, provided in the Topic 2 Resources, to generate a set of random numbers. Click on the “Get Sets’ link at the bottom left of the page to generate some data. (Note: If you are not able to access the link, you can randomly generate 10 numbers yourself for this calculation.)
RANDOM.ORG – Integer Set Generator
Imagine these numbers are the care satisfaction scores from a recent sample of discharged patients. Randomly select one row of numbers to use for the following calculations:
- What was the mean?
- What was the median?
- What was/were the mode/s?
- Given that the range of data was between 1 and 20, what do these numbers tell you about the overall satisfaction of the patients?
- If you were reporting these scores back to your supervisor, how would you explain or interpret these satisfaction scores?
