A graduate student needs to collect data for their thesis as soon as possible. They go about their normal routine (coffee shop, work, class, lunch at the library, class, library again, home) and at every point along the way, ask everyone around them to fill out their thesis survey. What sampling method do they use?

elizabeth loftus conducted a study to observe the reliability of eyewitnesses during the 1970s. their baseline was to define how accurate are the recollections of eyewitnesses.

her studies do not support the use of eyewitness. loftus mentions in her work that we are not required to recall some experiences, meaning that rarely an individual eyewitness testimony is trustworthy. a good example is presented in her work, where all individuals watched a video and were than asked "about how fast were the cars going when they hit/smash? ". the testimonies changed based on the word she used to make the question (hit or smash), proving the fragility.

they could find out our specific needs.
