the pretest <strong>and</strong> 9.93 in the posttest. This means that on an average, the students<br />

scored well (63.6%) on this question in the pretest itself. Almost all of the students<br />

scored above 90% in the posttest <strong>and</strong> their scores improved from pretest to posttest.<br />

The st<strong>and</strong>ard deviation of the scores was 3.14 <strong>and</strong> 0.23 in the pretest <strong>and</strong> posttest,<br />

respectively. This means that the deviation in the scores from the average was<br />

higher in the pretest than in the posttest. In fact, the deviation in the scores on the<br />

posttest was minimal.<br />
