You must select # Figures, select 3 from the drop-down box, and enter 2.70 in the answer value text<br />

field. In this case, the student responses 2.7 and 2.700 are graded incorrect.<br />

Setting a Margin of Error<br />

• To directly specify the margin of error, select Accept +/- err, and then enter the numeric<br />

value of the variance in the err text field.<br />

For example, if the correct answer is 3.142 and err = 0.001, the range of correct responses<br />

is between 3.141 and 3.143 (inclusive).<br />

• To specify the margin of error as the tolerance in the value of a significant digit, select Accept<br />

+/- k in the nth place, enter the floating-point value of the tolerance in the k text field, and<br />

then select the significant digit from the n drop-down box.<br />

For example, if the correct answer is 2.4, k = 5, and n = 3, the range of correct responses<br />

is between 2.35 and 2.45 (inclusive).<br />

• To specify the margin of error as a percentage of the correct answer, select Accept +/- perc%,<br />

and then enter the percentage in the perc text field.<br />

For example, if the correct answer is 3.141592 and perc = 1, the range of correct responses<br />

is between 3.11017608 and 3.17300792 (inclusive).<br />
