1. Compare and contrast probability sampling methods and non-probability sampling methods. What do they have in common? How are these methods different?
2. Discuss at least two common biases that can influence the quality and reliability of polling information.
3. Develop a sampling plan for the poll you created in the Scientific Method - Part 2 assignment. Be sure to include the following in your plan: target population, type of sample (Simple random? Convenience? Snowball? etc.), expected sample size, and how you will deploy your poll/survey questions (internet, social media, phone, etc.). Also, be sure to include your rationale for each.

Scientific Method- Part 2

2A. Definition of an Opinion Poll:

• An opinion poll serves as a methodological approach to collect and analyze people's opinions, preferences, or attitudes on a particular subject. It involves systematically gathering data from a selected sample within a larger population. For instance, imagine conducting an opinion poll about environmental awareness. Participants might be asked questions about their views on climate change, recycling habits, or support for environmental policies. The collective responses from the sample provide insights into the broader population's sentiments on environmental issues.

2B. Characteristics of Good Poll Questions:

• Clarity:Questions should be unambiguous and straightforward to ensure respondents understand the intended meaning.
• Unbiased Language:The language used in questions should be neutral and avoid favoring any particular response.
• Single Focus:Each question should address a specific aspect to prevent confusion and obtain precise responses.
• Neutrality:Questions should be free from inherent biases, ensuring respondents can express their views without external influence.
• Balanced Response Options:Response choices should encompass a range of perspectives, providing respondents with options that best represent their views.

Common Problems with Poll Questions:

• Double-Barreled Questions:Avoid combining multiple queries in one question to maintain clarity and accurate responses.
• Ambiguity:Questions should be clear, and terms should not be open to interpretation, reducing the likelihood of misunderstandings.
• Negative Wording:Negative phrasing may lead to confusion; questions should be positively framed whenever possible.
• Assuming Knowledge:Questions should not assume participants possess specific information, ensuring inclusivity and accuracy.

2C. Poll Questions for the Social Media and Mental Health Study:

1. Social Media Usage Frequency:"On a scale from 1 to 5, how frequently do you use social media platforms? (1 - Rarely, 5 - Very Frequently)"
2. Experience of Mental Health Issues:"Have you ever experienced feelings of anxiety or depression related to your social media usage? (Yes/No)"
3. Distressing Content Encounters:"How often do you encounter content on social media that you find distressing? (Rarely, Occasionally, Frequently)"
4. Perceived Impact:"Do you believe that social media has a positive impact on your mental well-being? (Agree/Disagree/Neutral)"

2D. Demographic Information:Gathering demographic details such as age, gender, educational background, employment status, and geographic location ensures a representative sample. This information aids in analyzing whether the impact of social media on mental health varies across different demographic groups, providing a more comprehensive understanding of the study's outcomes. For instance, age-related differences or variations based on geographical location can be crucial factors in interpreting the findings.
