An English professor wants to know if a reading program improves the speed at which children read. He gives them a reading exam before and after the program which measures the time needed to read a certain passage. He wants to know whether or not students' times decrease due to the program. Question 2 2 pts What type of test would you use in this situation? [Paired or independent samples] Edit View Insert Format Tools Table 14ptV ParagraphV B I U " iv T2v Here. given that the same sample of students takes the reading test before and after the program. So, the samples are not independent with respect to the measurements of time. Hence. we should use paired samples.
