As can be seen in Table 16, 25 students enrolled in the introductory biology course took this make-up exam scheduled on Friday at 4:00 p.m. This make-up exam was arranged to allow students who missed the regular exam, due to their evening commitments, to have a chance to take it.
At a first glance, from the "Average score(out of100)" data field, it appears that there is a big discrepancy between the scores of the last regular exam and those of the make-up exam. This discrepancy can be explained by the fact that the number of students who took the regular exam it's much more larger than of those who took the make-up exam. In cases like this the average score is not so eloquent. For this reason, the numbers in average score data field can be viewed as a rough estimate. Instead, three important factors that shouldn't be ignored in planning a make-up exam, and they were, are the scheduled date, the board examples, and the room environment. Taking into consideration that the students who took this make-up exam were supposed to have evening commitments during the week, Friday is wasn't really a good choice. Furthermore, the room environment can affect the students' power of concentration and in this particular case the temperature was a little bit too high. At last, the board examples, even if are not considered necessary, can help students to figure out more quickly what they are suppose to do, and thus to save them more time and be more efficient.
Looking at the data table, if there was indeed a discrepancy, I might say that a more appropriate explanation is that the make-up exam was not so well planned.
