Understanding Student Enrollment Data
The question asks us to find the average of the difference between the number of male and female students enrolled in the BA course over five years, from 2016 to 2020. To do this, we first need to examine the provided table and extract the relevant data for the BA course for each year.
| Year | B.sc | BA | B.Com | |||
|---|---|---|---|---|---|---|
| M | F | M | F | M | F | |
| 2016 | 380 | 220 | 520 | 405 | 200 | 80 |
| 2017 | 390 | 230 | 525 | 417 | 210 | 85 |
| 2018 | 395 | 235 | 535 | 427 | 212 | 87 |
| 2019 | 405 | 250 | 538 | 430 | 215 | 91 |
| 2020 | 415 | 275 | 543 | 438 | 221 | 97 |
Calculating the Difference in BA Enrollment by Gender
For each year from 2016 to 2020, we will find the difference between the number of male and female students enrolled in the BA course. The difference is calculated as: Number of Male Students - Number of Female Students.
- 2016: Difference = $520 - 405 = 115$
- 2017: Difference = $525 - 417 = 108$
- 2018: Difference = $535 - 427 = 108$
- 2019: Difference = $538 - 430 = 108$
- 2020: Difference = $543 - 438 = 105$
Finding the Total Difference
Now, we need to sum up the differences calculated for each year:
Total Difference = $115 + 108 + 108 + 108 + 105$
Total Difference = $544$
Calculating the Average Difference
To find the average difference, we divide the total difference by the number of years, which is 5 (2016, 2017, 2018, 2019, 2020).
Average Difference = $\frac{\text{Total Difference}}{\text{Number of Years}}$
Average Difference = $\frac{544}{5}$
Average Difference = $108.8$
Thus, the average of the difference between male and female students for the BA course during 2016-2020 is 108.8.

Additional Information: Data Interpretation and Average Calculation
Data interpretation questions often require extracting specific information from tables, graphs, or charts and performing calculations. Understanding how to calculate an average is a fundamental skill in such questions. The average (or mean) of a set of numbers is found by summing all the numbers in the set and then dividing by the count of numbers in the set. In this problem, we calculated the average difference by summing the yearly differences and dividing by the number of years.
Key concepts used:
- Reading data from tables.
- Calculating differences between two quantities.
- Calculating the average of a set of values.
