SAEE Analytical Reasoning & Data Interpretation

Question 1

A company's revenue increased from $2.4 million to $3.0 million over one year. What was the percentage increase?

Accepted Answer

25%

Answer

The increase is $0.6 million. Percentage increase = (0.6 / 2.4) × 100 = 25%. Always divide the change by the original value, not the new value.

Question 2

If a bar graph shows quarterly sales of 150, 200, 175, and 225 units, what is the average quarterly sales?

Accepted Answer

187.5 units

Answer

Average = (150 + 200 + 175 + 225) / 4 = 750 / 4 = 187.5 units. The mean is calculated by summing all values and dividing by the number of data points.

Question 3

In a pie chart, a sector representing 'Marketing' occupies 72 degrees. What percentage of the total budget does Marketing represent?

Accepted Answer

20%

Answer

A full circle is 360 degrees. The percentage is (72 / 360) × 100 = 20%. Each degree of the pie chart represents approximately 0.278% of the total.

Question 4

A table shows that Department A has 45 employees and Department B has 30 employees. What is the ratio of Department A to Department B staff?

Accepted Answer

3:2

Answer

The ratio 45:30 simplifies to 3:2 by dividing both numbers by their greatest common divisor (15). Ratios should always be expressed in their simplest form.

Question 5

If a trend line on a graph shows a negative slope, what does this indicate about the data?

Accepted Answer

The dependent variable decreases as the independent variable increases

Answer

A negative slope indicates an inverse relationship: as one variable increases, the other decreases. This is also called a negative correlation in statistical terms.
