These are original practice items written to the TEAS 7 blueprint (4 options, no penalty for wrong answers), not actual exam questions. Try each one before you open the answer.
Mathematics: data interpretation sits inside the Mathematics section of the TEAS 7. Our bank holds 66 verified items tagged to it, and the 4 below are a fixed sample so the page stays the same every time you open it. Each one shows the reasoning, not just the letter.
The topic tag comes from our own items rather than from a published syllabus, so treat it as a map of what we cover. For the official section breakdown see the TEAS 7 page.
Question 1
A bar chart shows the ages of 9 patients: 22, 25, 25, 30, 34, 34, 34, 40, 45. What is the median age?
Correct answer: B
The median is the middle value when data are ordered. With 9 numbers, the 5th value is 34.
Why the other options are wrong:
A: 33 is the average of 30 and 36, not present in the data.
C: 32 is the mean of 30 and 34, but median is 34.
D: 30 is the 4th value, not the median.
Question 2
A hospital recorded admissions: January: 480 patients; February: 552 patients. What is the percent increase in admissions from January to February?
Correct answer: A
Increase = 552 - 480 = 72. Percent increase = (increase ÷ original) × 100 = (72 / 480) × 100 = 0.15 × 100 = 15%.
Why the other options are wrong:
B: 13% could come from rounding error or using (72 ÷ 554) × 100.
C: 12% results from (72 ÷ 600) × 100, incorrectly using the new number as base.
D: 18% comes from (72 ÷ 400) × 100, dividing by a different value.
Question 3
The heart rates (bpm) of five patients are: 72, 78, 80, 84, 86. What is the mean heart rate?
Correct answer: A
Sum = 72 + 78 + 80 + 84 + 86 = 400. Mean = 400 / 5 = 80 bpm.
Why the other options are wrong:
B: 79 would result from a sum of 395, which is incorrect.
C: 78 is the median, not the mean.
D: 81 would result from a sum of 405, which is incorrect.
Question 4
A patient's systolic blood pressure readings over 5 days were: 118, 122, 130, 126, 124. What is the mean systolic blood pressure?
Correct answer: B
Mean = sum of values ÷ number of values. Sum = 118 + 122 + 130 + 126 + 124 = 620. 620 ÷ 5 = 124.
Why the other options are wrong:
A: 126 is the median (middle value when ordered), not the mean.
C: 128 might come from incorrectly summing (e.g., 118+122+130+126+124 = 620, but dividing by 5 gives 124, not 128).
D: 122 is the median of the first three numbers, not the mean.
