A random selection of files from a student counseling center revealed the following reasons why college students seek services:
Mental health issues 25
Learning/school issues 15
Relationship issues 5
Other 5
What does it mean to say the files were randomly selected?
How would the researcher randomly select files? (What does the process look like?)
What is the probability that if we pulled another student file from the counseling center the student would fall in each of the following categories a) mental health issues, b) learning/school issues OR relationship issues, c) any category except other?
Would our probabilities and results be different if we used convenience sampling? Why or why not?
How would you like us to help you with this assignment?

Sounds like they just grab folders
To say that the files were randomly selected means that every file in the student counseling center had an equal chance of being included in the sample. This approach ensures that the selection is unbiased and representative of the entire population.
The process of randomly selecting files can be done in several ways. One common method is to use a computer-generated random number sequence. The researcher assigns a unique number to each file, then generates a random number sequence. They would then select files based on the order determined by the random number sequence until the desired sample size is reached.
To calculate the probability of selecting another student file falling into each category, we need to know the total number of files in the counseling center.
a) If there are 50 files in total, the probability of selecting a student seeking mental health services would be: 25/50 = 0.5 or 50%.
b) If we consider both learning/school issues and relationship issues, the probability would be: (15 + 5)/50 = 20/50 = 0.4 or 40%.
c) To calculate the probability of selecting any category except for 'Other,' we need to subtract the probability of selecting 'Other' from 1. If 'Other' has 5 files, and the total number of files is 50, then the probability would be: (50-5)/50 = 45/50 = 0.9 or 90%.
If convenience sampling were used instead of random sampling, the probabilities and results would likely be different. Convenience sampling involves selecting individuals who are convenient and readily available for the study. This introduces potential bias, as it may not accurately represent the entire population. The distribution of reasons for seeking counseling services might not reflect the actual proportion in the population, leading to different probabilities.
