A college has four programs B.A., B.Sc., B.Com. and B.B.A. The results of the mid-semester and end-semester tests are shown in the table given below.Results Number of students Β.Α. B.Sc. B.Com. Β.Β.Α. Failed in both tests 28 23 17 27 Failed in mid-semester test but passed in end-semester test 14 12 8 13 passed in mid-semester test but failed in end-semester test 6 17 9 15 Passed in both tests 64 55 46 76
Program Difficulty Comparison
The objective is to identify the program with the least difficult mid-semester test. The criterion used is the number of students passing the test.
A test is considered least difficult when the highest number of students pass it. To find this, we calculate the total number of students who passed the mid-semester test for each program.
Students who passed the mid-semester test are those who either:
- Passed the mid-semester test but failed the end-semester test.
- Passed both the mid-semester and end-semester tests.
Calculate Mid-Semester Passers
From the given table, the relevant data for students passing the mid-semester test are:
| Results | B.A. | B.Sc. | B.Com. | B.B.A. |
|---|---|---|---|---|
| Passed in mid-semester test but failed in end-semester test | 6 | 17 | 9 | 15 |
| Passed in both tests | 64 | 55 | 46 | 76 |
Now, calculate the total number of students who passed the mid-semester test for each program:
- B.A.: $6 + 64 = 70$ students
- B.Sc.: $17 + 55 = 72$ students
- B.Com.: $9 + 46 = 55$ students
- B.B.A.: $15 + 76 = 91$ students
Identify Least Difficult Mid-Semester Test
Compare the number of students passing the mid-semester test across all programs:
- B.A.: 70
- B.Sc.: 72
- B.Com.: 55
- B.B.A.: 91
The B.B.A. program recorded the highest number of students (91) passing the mid-semester test. This indicates that the mid-semester test for B.B.A. was the least difficult among the programs.
