<p class="">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.<u></u><u></u></p>
<p class=""><u></u> <u></u></p>
<p class="">Is this the case, or am I ok in teaching that dropdown lists ensure reasonable entry of data?<u></u><u></u></p>
