Use the following information to answer the next three exercises: A Lake Tahoe Community College instructor is interested in the mean number of days Lake Tahoe Community College math students are absent from class during a quarter.1.1. What is the population she is interested in?a. all Lake Tahoe Community College studentsb. all Lake Tahoe Community College English studentsc. all Lake Tahoe Community College students in her classesd. all Lake Tahoe Community College math students
2. The instructor takes her sample by gathering data on five randomly selected students from each Lake Tahoe CommunityCollege math class. The type of sampling she used isa. cluster samplingb. stratified samplingc. simple random samplingd. convenience sampling This study investigated the cognitive effects of stimulant medication in children with mental retardation and Attention-Deficit/Hyperactivity Disorder. This case study shows the data for the Delay of Gratification (DOG) task. Children were given various dosages of a drug, methylphenidate (MPH) and then completed this task as part of a larger battery of tests. The order of doses was counterbalanced so that each dose appeared equally often in each position. For example, six children received the lowest dose first, six received it second, etc. The children were on each dose one week before testing. This task, adapted from the preschool delay task of the Gordon Diagnostic System (Gordon, 1983), measures the ability to suppress or delay impulsive behavioral responses. Children were told that a star would appear on the computer screen if they waited "long enough" to press a response key. If a child responded sooner in less than four seconds after their previous response, they did not earn a star, and the 4-second counter restarted. The DOG differentiates children with and without ADHD of normal intelligence (e.g., Mayes et al., 2001), and is sensitive to MPH treatment in these children (Hall & Kataria, 1992). Design Issues This is a repeated-measures design because each participant performed the task after each dosage.
