Identify actions or conditions that may induce systematic errors in each scenario and explain the direction of the impact

Read the following scenarios.Identify actions or conditions that may induce systematic errors in each scenario and explain the direction of the impact(i.e., whether the observed data will be pulled up or down from the actual value).Scenario 1: In an experiment that investigates how novice users learn to use the T9 method to enter data into a PDA, a participant has actually used T9 for over a year.Scenario 2: An experimenter is introducing a website to a participant. The experimenter says, “My team has spent six months on this site. The site is like our baby.”Scenario 3: In an experiment that examines how individuals with severe motor disabilities interact with computers using a brain-computer interface, all participantsrecruited are healthy individuals without any disability.Scenario 4: In an experiment that examines speech-based dictation techniques, the experimenter forgets to switch the speech profiles between experiment sessions,so a participant used another person’s speech profile to complete the dictation tasks.Scenario 5: In an experiment that examines the design of an e-commerce website, participants complete multiple tasks to retrieve specific information on the site.However, the network speed is very slow and the participants have to wait significant amounts of time for each page to be loaded.
