Identify the sampling method in the following scenarios. Based on the sampling method, is the research likely to have high or low external validity? Scenario Researchers at PCC are interested in knowing about academic success of PCC students. They compile a list of all students' emails and use a random number generator to select a sample of 4000 students to survey. Parker is a graduate student writing a thesis. They are researching attitudes about drug use among clubgoers. To collect data, Parker spends the weekends standing in entryways of clubs asking patrons to take their survey. Parker only goes to clubs they are familiar with and only collects data in Los Angeles, since that is where they live. Brooke is researching the likelihood that people under 30 will conform to an authority figure. Brooke generates a list of phone numbers of all people under 30 in the US, and has a random phone selector print a sample of 3000 phone numbers. However, Brooke believes that people living in rural areas will respond differently than people in urban areas. Therefore, she sets things so that random phone selector to pull numbers at random, proportionate to the number of urban and rural people living in the US. Judy Chu is running to represent California's 27th district in the House of Representatives. She wants to know how likely voters would be to vote for her. To determine this, Representative Chu divides the 27th district by neighborhood and then randomly selects 20 neighborhoods to survey. Everyone who lives in the 20 neighborhoods is invited to participate in the survey. Researchers want to survey K-12 students about their socialization skills during the COVID pandemic. Researchers start by recruiting a small sample of 20 students, and then ask each of these 20 students to refer the researchers to 5 more potential participants. Researchers keep asking new participants to refer them to 5 more people. Sampling Method High or Low External Validity
