1. In life, we often find ourselves faced with decisions that require careful consideration. Statistics serves as a valuable tool in aiding us through this process, offering insights, patterns, and probabilities that empower us to make more informed and rational choices

2. As students, managing our allowance effectively is crucial, and statistics plays a vital role in assisting us with this task. By utilizing statistical tools, we can analyze our spending patterns, identify priorities, and make informed financial decisions to ensure that our allowance is budgeted wisely

3. When students are heading to school, it's essential to analyze patterns to ensure they arrive at the proper time. This is where statistics comes into play, helping students understand trends in traffic, estimate travel times, and make informed decisions about when to leave, ensuring punctuality and efficient time management.

-The software that comes to mind right now are Google Sheets and Microsoft Excel, as they are applications that can assist in organizing statistical studies. These spreadsheet applications offer tools for both data management and visualization, contributing to their widespread accessibility and frequent use in statistical tasks.

Which of them do you feel would have simple random samplings as an appropriate sampling method?

I believe that simple random sampling would be suitable for both "A survey of Olongapo City residents' attitude toward Nuclear Power Plants" and "College students' acceptability of school policies on discipline."

In the scenario of the survey regarding Olongapo City residents' attitude toward Nuclear Power Plants, simple random sampling is appropriate because all participants are from Olongapo City, meaning they could potentially be affected by the presence of Nuclear Power Plants. Utilizing this method ensures that there are no subjective biases or perspectives influencing the data. The insights gathered from the participants represent the collective views of Olongapo citizens.

In the scenario of "College students' acceptability of school policies on discipline," simple random sampling is appropriate because all students experience the school policies on discipline within the campus.

Are there any limitations?

Yes, there’s a limitation like even when choosing participants randomly, mistakes can still happen, like picking people who don't really represent the whole group or not getting responses from everyone asked. These mistakes can make the study's results less accurate and harder to use for understanding everyone. It's important for researchers to be careful about these issues to make sure their findings are trustworthy.

In which would random sampling be totally inappropriate?

I think it would be inappropriate in “A survey of TikTok users following a Famous TikTok Celebrity”, because randomly picking people from all over might not get the right kind of people for TikTok fans of a particular celebrity.  We need to choose them more carefully to make sure we're getting the right information from the right people. So, instead of just picking randomly, follow them on TikTok to ask them directly.

In each of the examples below, identify the sampling frame you would use if you were to undertake a simple random sample.

A survey of disco goers on a Friday or Saturday night- People that are present at the disco on Friday or Saturday night.

A study of employees' attitude towards family planning in DR. VICTOR R. POTENCIANO MEDICAL CENTER- Employees at DR. VICTOR R. POTENCIANO MEDICAL CENTER.

A survey of Olongapo City resident's attitude to Nuclear Power Plants- Citizens of Olongapo City.

A survey of TikTok users following a Famous TikTok Celebrity- Followers of the Famous TikTok Celebrity on TikTok.

College students' acceptability of school policies on discipline- Students that are registered in the designated college.

Mental Health Status of RTU students doing online classes- Students enrolled at RTU (Rizal Technological University)who are currently engaged in online classes.

1. Another factor that could be utilized when conducting a stratified sample of the adult population in a particular city other than marital status is the educational achievement of the respondents, dividing or categorizing them based on their level of schooling, diploma, or degree.

2. To ensure precision, we begin by adding the number of part-time and full-time staff, which totals 700 employees. We aim to conduct 20 interviews. Calculating the percentage of part-time and full-time staff reveals that part-time staff constitute 21.4%, while full-time staff make up 78.6%. Multiplying the total number of interviews (20) by the respective percentages yields 4.28 for part-time staff and 15.72 for full-time staff. As we can't conduct a fraction of an interview, rounding these figures gives us 4 interviews for part-time staff and 16 for full-time staff. Thus, we need to interview 16 full-time and 4 part-time employees to accurately represent the workforce proportions.

3. One possible sampling frame is comprised of residential addresses nationwide, enabling the random selection of households for interviewing residents. Using a multi-stage cluster sampling approach, the country can be divided into administrative regions, provinces, cities, barangays, and enumeration areas. This method enables efficient sampling of diverse individuals across various geographic levels, ensuring representation while minimizing costs and resources.

4. To conduct a purposive sample of individuals aged 60 and above in Zambales' isolated area, efforts would include intentionally selecting participants of both genders and diverse age groups, ranging from the very old to recently retired individuals. To ensure representation across socio-economic backgrounds, engagement with community leaders and local organizations would be essential, while designing interview questions to explore pertinent topics related to aging, retirement, and socio-economic status.

5. Conducting a convenience sample of individuals walking on Boracay Island's main street on a Sunday morning may result in tourists and leisure seekers being over-represented due to the island's popularity as a tourist destination and the timing conducive to leisure activities. Conversely, local residents, working individuals, elderly individuals, and families with young children may be under-represented, as they may have other commitments, prefer quieter environments, or opt for alternative activities on Sundays.

6. When administering a questionnaire on college students' attitudes towards banking services at BANK ZZZ through a convenience sample at the Students Organization's bar, socially active and older students may be overrepresented, while commuter students, studious individuals, and non-drinkers may be underrepresented. Recognizing these potential biases is crucial for interpreting the findings accurately, as they may not fully reflect the diverse range of attitudes among all college students at BANK ZZZ.

7. To attract participants for a self-selected sample, various strategies can be employed such as online advertising, email campaigns, partnerships with relevant organizations, event participation, and word-of-mouth promotion. However, the primary drawback of self-selection is the inherent risk of sampling bias, as individuals who choose to participate may possess different characteristics or motivations compared to those who do not, potentially limiting the generalizability of the findings.
