UMAT Data Interpretation 3

Question 1

A graph shows healthcare spending (in billions) for five countries: A=5, B=12, C=8, D=15, E=10. What is the median spending?

Accepted Answer

10

Answer

Ordered values: 5, 8, 10, 12, 15 — the median (middle value) is 10.

Question 2

A UMAT table shows that a test has a false positive rate of 20%. In a group of 500 healthy patients, approximately how many will incorrectly test positive?

Accepted Answer

100

Answer

False positive rate of 20% means 20% of healthy patients test positive: 0.20 × 500 = 100 patients.

Question 3

A line graph shows two hospitals' patient satisfaction scores over 5 years. Hospital A shows a steady increase while Hospital B fluctuates. The most valid conclusion is:

Accepted Answer

Hospital A shows a more consistent improvement trend than Hospital B

Answer

A steady increase indicates a consistent trend, while fluctuation shows variability — the graph only supports a statement about observed trends, not future predictions.

Question 4

In a UMAT data set, the mean is significantly higher than the median. This most likely indicates:

Accepted Answer

The data is skewed right with some very high values pulling the mean up

Answer

When the mean exceeds the median, the distribution is typically right-skewed, with high outliers pulling the mean upward.

Question 5

A UMAT question presents a table showing that risk of disease X increases with age. The data shows 2% risk at age 20, 5% at age 40, 12% at age 60. This pattern is best described as:

Accepted Answer

Accelerating/non-linear growth with age

Answer

The risk increases at an accelerating rate (2% to 5% is +3%, then 5% to 12% is +7%), indicating a non-linear, accelerating pattern rather than steady linear growth.
