Pew Research Article and Methodology Please read the following article (this is similar to the results section of a report) and methodology by Pew Research. Then answer the questions and complete the statements located under the links. - Social Media Update 2016, Facebook usage and engagement is on the rise, while adoption of other platforms holds steady (opens in a new window) - Methodology (opens in a new window) Based on the article what question do you think the researchers were trying to answer? \( \square \) Study the graphical tables and charts. Which of the following variables is least likely to be the focus of a survey question? \( \square \) The methodology included: - The data was collected using a(n) \( \square \) method. - The data was collected between March \( \square \) 7 and April \( \square \) 2016. - The population of interest is all US adults, \( \square \) years of age or \( \square \) (Notice that the methodology defined what was meant by adult.) - The sample was selected using a combination of landline and \( \square \) random-digit-dial. Random-digit-dial means that it randomly dials phone numbers so that even people with unlisted numbers are included in the sampling frame. - How was the sample selected?

To answer your questions based on the Pew Research article and methodology, let's break down each part step by step. 1. **Research Question**: The researchers were likely trying to answer the question: "How are social media usage and engagement patterns changing among U.S. adults in 2016?" This encompasses the rise of Facebook usage and the steady adoption of other platforms. 2. **Least Likely Variable**: The variable least likely to be the focus of a survey question could be something unrelated to social media usage, such as "favorite color" or "type of pet owned." These variables do not directly relate to the study's focus on social media engagement. 3. **Data Collection Method**: The data was collected using a(n) **telephone survey** method. 4. **Data Collection Dates**: The data was collected between March **7** and April **4** 2016. 5. **Population of Interest**: The population of interest is all U.S. adults, **18** years of age or **older**. 6. **Sample Selection Method**: The sample was selected using a combination of landline and **cellphone** random-digit-dial. 7. **Sample Selection Process**: Interviews were conducted in English and **Spanish**. Respondents in the landline sample were selected by randomly asking for the **next** adult male or female who was at home. Cellphone interviews were conducted with the person who answered the phone as long as they were 18 years of age or older. 8. **Sample Composition and Size**: This sample was made up of **1,500** adults. **1,000** were interviewed on a landline telephone and **500** were interviewed on a cellphone. 9. **Data Weighting Specifics**: The methodology likely included weighting the data to match the demographic distribution of the U.S. adult population based on factors such as age, gender, race, and geographic location. 10. **Replicability of the Study**: Based on the methodology presented in the report, if I had the resources, I would be able to replicate this study, as the methodology is clear and provides a structured approach to data collection. 11. **Undercoverage Bias**: This survey was biased due to undercoverage. Individuals who were omitted from the sampling frame include those who do not have a landline or cellphone, such as those who are completely offline or rely solely on internet-based communication. 12. **Sampling Technique Reasoning**: A potential reason the research company may not have chosen this type of sampling technique could be the desire for a more comprehensive approach that includes online surveys or focus groups, which could capture a broader range of social media users. 13. **Impact of Bias on Validity**: Yes, this bias could change the validity of the article. If certain demographics are underrepresented, the findings may not accurately reflect the social media usage patterns of the entire U.S. adult population.
