Question

A teacher estimates there are about 600 students at their school. If there are actually 625 students, then what is the percent error of this estimate?

Answer 1

4%

Explanation:

(|600-625|)/625 x 100

=4%

Answer 2

The percent error for this estimate was 4%.

Explanation:

Teacher's estimated students = 600

Actual students = 625

625-600 = 25 students are more than the teacher's estimate.

In other words, the measurement error = 25 students

Now the percent error can be calculated by dividing 25 (measuring error) by the actual students.

Percent error = 25/625 = 0.04 which is 4%

Therefore, the percent error for this estimate was 4%.
