Question
TABLE 10.2
A course can be taken for credit either by attending lecture sessions at fixed times
and days, or by doing online sessions that can be done at the student's own pace and
at those times the student chooses. The course coordinator wants to determine if these
two ways of taking the course resulted in a significant difference in achievement as
measured by the final exam for the course. Table 10.2 gives the scores on an exami-
nation with 45 possible points for one group of n₁ = 9 students who took the course
online, and a second group of n₂ = 9 students who took the course with conventional
lectures. Do these data present sufficient evidence to indicate that the average grade
for students who take the course online is significantly higher than for those who attend
a conventional class?
