University Entrance Exam Data Analysis and Qualification Difference
The question asks us to find the difference between the total number of students who qualified for graduate-level examinations (B.Sc + B.A.) and post-graduate level examinations (M.Sc + M.A.) over the period from 2016 to 2020, based on the provided table.
Let's first look at the data provided in the table:
| Year | BSc | BA | MSc | MA | ||||
|---|---|---|---|---|---|---|---|---|
| A | Q | A | Q | A | Q | A | Q | |
| 2016 | 3.4 | 1.2 | 6.4 | 2.3 | 2.8 | 1.3 | 4.8 | 2.4 |
| 2017 | 3.6 | 1.8 | 6.6 | 2.5 | 2.4 | 1.1 | 4.7 | 2.3 |
| 2018 | 4.2 | 2.1 | 7.2 | 2.8 | 2.2 | 1.2 | 4.6 | 2.5 |
| 2019 | 4.8 | 2.3 | 6.8 | 2.6 | 2.5 | 1.2 | 4.9 | 2.7 |
| 2020 | 3.8 | 1.9 | 7.4 | 3.2 | 2.6 | 1.3 | 5.2 | 3.2 |
The table shows the number of candidates in thousands. 'A' stands for Appeared and 'Q' stands for Qualified.
Calculate Total Qualified Graduate Students (B.Sc + B.A.)
We need to sum the number of qualified students for B.Sc and B.A. for each year from 2016 to 2020 and then sum these annual totals.
- 2016: Qualified B.Sc + B.A. = $1.2 + 2.3 = 3.5$ thousand
- 2017: Qualified B.Sc + B.A. = $1.8 + 2.5 = 4.3$ thousand
- 2018: Qualified B.Sc + B.A. = $2.1 + 2.8 = 4.9$ thousand
- 2019: Qualified B.Sc + B.A. = $2.3 + 2.6 = 4.9$ thousand
- 2020: Qualified B.Sc + B.A. = $1.9 + 3.2 = 5.1$ thousand
Total Qualified Graduate Students (2016-2020) = $3.5 + 4.3 + 4.9 + 4.9 + 5.1 = 22.7$ thousand.
Calculate Total Qualified Post-Graduate Students (M.Sc + M.A.)
Similarly, we sum the number of qualified students for M.Sc and M.A. for each year from 2016 to 2020 and then sum these annual totals.
- 2016: Qualified M.Sc + M.A. = $1.3 + 2.4 = 3.7$ thousand
- 2017: Qualified M.Sc + M.A. = $1.1 + 2.3 = 3.4$ thousand
- 2018: Qualified M.Sc + M.A. = $1.2 + 2.5 = 3.7$ thousand
- 2019: Qualified M.Sc + M.A. = $1.2 + 2.7 = 3.9$ thousand
- 2020: Qualified M.Sc + M.A. = $1.3 + 3.2 = 4.5$ thousand
Total Qualified Post-Graduate Students (2016-2020) = $3.7 + 3.4 + 3.7 + 3.9 + 4.5 = 19.2$ thousand.
Calculate the Difference
Now, we find the difference between the total number of qualified graduate students and the total number of qualified post-graduate students from 2016 to 2020.
Difference = Total Qualified Graduate Students - Total Qualified Post-Graduate Students
Difference = $22.7 - 19.2 = 3.5$ thousand.
Since the numbers are in thousands, the actual difference in the number of students is:
$3.5 \times 1000 = 3500$ students.
Thus, the difference between the total number of students who qualified for graduate level examination (B.Sc + B.A.) and post graduate level (MSc + MA) examination during 2016 - 2020 is 3500.
Revision Table: University Entrance Exam Qualification Data
| Year | Qualified Graduate (thousands) | Qualified Post-Graduate (thousands) |
|---|---|---|
| 2016 | 3.5 | 3.7 |
| 2017 | 4.3 | 3.4 |
| 2018 | 4.9 | 3.7 |
| 2019 | 4.9 | 3.9 |
| 2020 | 5.1 | 4.5 |
| Total (2016-2020) | 22.7 | 19.2 |
Difference = $22.7 - 19.2 = 3.5$ thousand or 3500.
Additional Information: Understanding Data Interpretation Tables
Data interpretation questions often involve analyzing tables, charts, or graphs to extract specific information and perform calculations. Key aspects to consider include:
- Carefully reading the question to understand what is being asked.
- Identifying the relevant data points in the table or chart.
- Paying attention to units (e.g., thousands, millions, percentages).
- Performing the required calculations (sum, average, difference, ratio, percentage change, etc.).
- Ensuring the final answer is in the correct format and units.
- Breaking down complex problems into smaller, manageable steps.
In this problem, we needed to identify qualified candidates for specific courses over multiple years and then calculate sums and a difference. This type of question tests your ability to accurately read and process tabular data.
