Question 1

A double bar chart compares male and female university graduates in Saudi Arabia. Males: 2020: 45,000, 2023: 50,000. Females: 2020: 55,000, 2023: 70,000. What was the female growth rate?

Accepted Answer

27.3%

Answer

Female growth = ((70,000 - 55,000) / 55,000) × 100 = (15,000/55,000) × 100 = 27.3%. Female graduation numbers grew at a faster rate than male numbers.

Question 2

A stacked bar chart shows Saudi exports: Oil SAR 800B, Petrochemicals SAR 150B, Other SAR 50B. What percentage of total exports are non-oil?

Accepted Answer

20%

Answer

Total exports = 800 + 150 + 50 = SAR 1,000B. Non-oil = 150 + 50 = SAR 200B. Percentage = (200/1,000) × 100 = 20%.

Question 3

Data shows population of Saudi cities (millions): Riyadh 7.6, Jeddah 4.7, Makkah 2.0, Madinah 1.5, Dammam 1.2. What is the median?

Accepted Answer

2.0

Answer

Arranged in order: 1.2, 1.5, 2.0, 4.7, 7.6. The median (middle value) of 5 numbers is the 3rd value = 2.0 million.

Question 4

A scatter plot shows a positive correlation between study hours and Qudurat scores. If the trend line equation is y = 5x + 40, what score would you predict for 10 hours of study?

Accepted Answer

90

Answer

Using the equation: y = 5(10) + 40 = 50 + 40 = 90. Linear trend equations allow predictions based on the established pattern in the data.

Question 5

A table shows Qudurat score distribution: 60-70: 15%, 70-80: 30%, 80-90: 35%, 90-100: 20%. If 10,000 students took the exam, how many scored 80 or above?

Accepted Answer

5,500

Answer

Students scoring 80+: 35% + 20% = 55%. Number = 55% × 10,000 = 5,500 students.
