<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I am just going through the sample exam 1 2013 from VITTA that my students completed over the holidays. Question 12 of multi choice gives two interfaces and then a range of answers.
The correct answer says that the second interface (That makes use of dropdown boxes) ensures
<i>accurate</i> input of data. All year I have taught that validation methods such as this ensure
<i>reasonable</i> input of data as even with a limited amount of choices it still isn’t necessarily accurate. I seem to remember past exam questions on this as well.<o:p></o:p></p>
