A survey published by the Department of Education reported on the number of schools, learners and teachers in ordinary public schools and independent schools during 2013 - NSC Mathematical Literacy - Question 5 - 2017 - Paper 1

To find the total number of teachers, we sum the values provided in Table 3 for each province. The total number of teachers in South Africa for 2013 is 425,023.

To calculate the percentage of schools in KwaZulu-Natal, use the formula:

ext{Percentage of Schools} = rac{ ext{Number of Schools in KZN}}{ ext{Total Number of Schools}} imes 100

Assuming there are 12,000 schools in KZN and 50,000 total:

ext{Percentage} = rac{12,000}{50,000} imes 100 = 24\%

The Learner-School Ratio (LSR) for Gauteng can be calculated using the LSR formula:

$LSR = \frac{\text{Number of Learners in Gauteng}}{\text{Number of Schools in Gauteng}}$

Assuming there are 2,649 learners and 84 schools in Gauteng:

$LSR = \frac{2,649}{84} \approx 31.5$

The modal ratio is the most frequently occurring learner-school ratio among the provinces. After analyzing the values, the modal ratio is found to be 30.1.

Arranging the learner-school ratios from highest to lowest:

• 31.5 (Gauteng)
• 30.1
• 29.8
• and so forth.

To find the median, list the ratios in numerical order:

• 29.8
• 30.1
• ...

With an even number of values, the median will be the average of the two middle values. Assuming the middle values are 30.1 and 30.3, the median is:

$\text{Median} = \frac{30.1 + 30.3}{2} = 30.2$

Collect the Teacher-School Ratios (TSR) for each province and accurately plot each ratio on the attached graph, ensuring proportions are maintained.
