Final answer:
Telephone interviews are largely unreliable due to various factors such as limited phone access and non-representative samples. CATI and robo-polls can also introduce errors and reliability issues.
Step-by-step explanation:
Telephone interviews are largely unreliable. This statement is true. There are several factors that make telephone interviews less reliable, such as the fact that not everyone has a telephone, cell phone numbers being unlisted, and individuals not being available during the phone call. These factors result in a non-representative sample of the population.
Additionally, computer-assisted telephone interviewing (CATI) and robo-polls can introduce errors and reliability issues. Therefore, it is important to consider the limitations of telephone interviews when gathering data.
