Praxis 5511 Practice Test Practice Question
On a particular winter day, a town recorded temperatures throughout the day of -5, -2, 0, 4, 7, 6, 3, and 1. In degrees Celsius. What is the range of temperatures in degrees Celsius, in the town on that day?
Correct Answer: D
Rationale: To determine the range of temperatures, subtract the lowest recorded temperature from the highest. In this case, the lowest temperature is -5°C and the highest is 7°C. Calculating the range: 7 - (-5) = 7 + 5 = 12°C.
Option A (2) is incorrect as it does not account for the full spread of temperatures. Option B (6) miscalculates the difference between two temperatures but overlooks the extremes. Option C (8) similarly fails to capture the correct span, as it suggests a smaller range than what exists. Thus, the range of 12°C accurately reflects the difference between the highest and lowest temperatures recorded.
