Answering Answer-Dependent Numerical Questions

Some numerical questions have multiple parts that require you to enter estimated or measured values and then perform calculations based on the values you entered. These questions are often used for lab classes to record the results of an experiment and perform analysis of the data.

For these questions, the answer boxes for analyses are not enabled and are displayed with a gray background until you have entered the required values first.

If you click an answer box that is not enabled, a message is displayed indicating that you must complete other answer boxes first.

  1. Enter the requested values, specifying units or significant figures if required.

    After the required values have been entered, answer boxes for calculations dependent on those values are enabled and are displayed with a white background.

  2. Enter your calculations in the appropriate answer boxes, specifying units or significant figures if required.
    For these questions, your answers are scored based on the expected range for the question and your analyses are scored based on the values you provided.
    • Your answers are marked correct if they are within the expected range and correctly specify units or significant figures, if required.

    If your answers are not within the expected range, they are marked incorrect; a prompt might also be displayed indicating why the values were not acceptable.

    • Your analyses are marked correct only if your answers are within the expected range and you have performed the calculations correctly, including units and significant figures, if required.

    If your answers are not within the expected range but your calculations were correct for the values you provided, an icon correct calculation, wrong answer is displayed to let you know that your procedure was correct; however, no points are awarded unless both the values and the calculations are correct.
