Analysing University Enrollment Data

The question asks us to find the university for which the difference in the number of girls enrolled between the years 2019 and 2015 is the minimum. To solve this, we need to calculate the difference in enrollment for each university (A, B, and C) between these two years and then compare the differences.

Let's extract the enrollment numbers for each university in 2015 and 2019 from the given table:

Calculating the Enrollment Difference (2019 - 2015)

Now, we calculate the difference for each university:

• For University A:
  Difference = Number of girls in 2019 - Number of girls in 2015
  Difference = \(25,000 - 15,000 = 10,000\)
• For University B:
  Difference = Number of girls in 2019 - Number of girls in 2015
  Difference = \(20,000 - 10,000 = 10,000\)
• For University C:
  Difference = Number of girls in 2019 - Number of girls in 2015
  Difference = \(22,500 - 5,000 = 17,500\)

Comparing the Differences

We have the following differences:

• University A: 10,000
• University B: 10,000
• University C: 17,500

Comparing these values, we can see that the minimum difference is 10,000, which occurs for both University A and University B.

Therefore, the difference between the number of girls enrolled in the year 2019 and 2015 is minimum for both University A and University B.

The minimum difference is 10,000, found in both University A and University B.

Additional Information on Data Interpretation

Data interpretation questions often require you to extract specific information from tables, charts, or graphs and perform calculations or comparisons based on that information. Key skills needed include:

• Reading the Data: Carefully understand what the rows, columns, and labels represent in a table or what the axes and points represent in a graph.
• Identifying Relevant Data: Pinpoint the exact numbers or values needed to answer the question, ignoring irrelevant data.
• Performing Calculations: Apply basic arithmetic operations like addition, subtraction, multiplication, division, or percentage calculations as required by the question.
• Comparison: Compare values to find the largest, smallest, or differences, as done in this problem.
• Understanding Trends: Sometimes, questions might ask about trends over time, requiring you to look at changes across different years or periods.

Practicing with different types of data representations will help you become more comfortable and efficient in data interpretation tasks.
