P2 W2for This Assignment You Will Be Required To Use Microsoft Excel

For this assignment, you will be required to use Microsoft Excel to generate a random sample. In a healthcare organization where you manage a clinic with approximately 1,500 patients monthly, determine the appropriate sample size based on consultation with a statistician—30 patients in this case. Create a list of numbers from 1 to 1,500 in Excel, representing your patient population. Using Excel functions, generate a random sample of 30 patients from this list. Submit an Excel file that shows both the full list and the randomly selected sample. Additionally, provide a narrative explaining the steps and Excel functions used to complete this task. Include in your narrative how this skill set is applicable in your current or future career. Also, discuss when a simple random sample versus a stratified random sample would be appropriate.

Random sampling is a fundamental statistical technique essential in healthcare research for ensuring that samples accurately represent the population, thereby improving the validity and reliability of findings (Larke et al., 2019). In this context, generating a random sample from a patient population using Microsoft Excel involves straightforward steps complemented by useful functions like RAND and RANDBETWEEN. The process begins with creating a sequential list of numbers representing the entire patient population—numbers 1 through 1500—by entering '1' and '2' in cells A1 and A2, respectively, then dragging the fill handle down to cell A1500, which automatically fills the series. Next, to select a random sample of 30 patients, the RAND() function can be applied to assign a random decimal to each list item, or the RANDBETWEEN() function can generate random numbers between 1 and 1500. For example, inserting '=RAND()' in column B next to each number, then sorting the entire list based on these random numbers, will effectively randomize the list. Selecting the top 30 entries after sorting yields the random sample. Alternatively, using RANDBETWEEN() to generate random numbers in a new column facilitates the same outcome by sorting accordingly and selecting the first 30 numbers. This process is not only quick but also reproducible, ensuring fairness in patient selection. In a professional setting, such as healthcare management, this skill helps conduct unbiased surveys or assessments. For example, in patient satisfaction surveys, random sampling ensures that feedback is representative of the entire patient population, enhancing the validity of insights gained. Moreover, understanding how to generate random samples with Excel is crucial for designing research, quality improvement projects, or resource allocations efficiently. This skill can be extended to various healthcare settings, such as selecting providers for quality audits or staff surveys, ensuring equitable and unbiased selection procedures.

Simple random sampling (SRS) is suitable in scenarios where each individual in the population has an equal chance of being selected, which minimizes bias (Creswell & Creswell, 2018). An example of this in healthcare would be randomly selecting patients for a small-scale clinical trial, ensuring every patient has an equal opportunity to be included. SRS is advantageous for its simplicity and fairness but becomes less practical with larger populations due to logistical challenges. Conversely, stratified random sampling involves dividing the population into subgroups or strata (e.g., age, gender, or diagnosis categories), then randomly sampling from each stratum proportionally. This method ensures representative sampling across key segments, making it ideal for heterogeneous populations. For instance, assessing patient satisfaction across different age groups would benefit from stratified sampling, guaranteeing proportionate representation and more nuanced insights (Lohr, 2019). Although slightly more complex and requiring prior knowledge of population subgroups, stratified sampling enhances accuracy in reflecting the diverse characteristics within a population.
