Answer to Question #132935 in Economics for rahul

Question

Question 1 - The researcher not only observes if a student is assigned a laptop, but also observes if the students indeed used the laptop or not (some students do not use the laptops because they don't think they are useful for their high- school work, and some others have access to a family desktop computer in their homes). The problem that not all the students that were randomly assigned a laptop actually use it is known as

a. failure to randomize

b. attrition

c. partial compliance

d. experimental effect

Answer 1

Attrition occurs when participants leave during a study. Systematic differences between people who leave the study and those who continue can introduce bias into a study's results – this is attrition bias.

So, the correct answer is b.
