Frequency Distributions - Essay ExampleInitially, there was a bimodal distribution, showing that students were grouped into those that understood better (scores that forgather around the top of the scale) and those that did not understand as well (scores clustering near the lower end of the scale). By the second week, the two groups of students did combine into whizz unified group but the bulk still did have trouble grasping the concepts in class. A minority of students did far better than the rest and got last score while the majority still scored towards the lower side of the scale. Scores from the third week show that the class as a whole was starting signal to make sense of the concepts being taught, and were improving in their understanding. This can be understood from the movement of the majority of the scores from below the 50% mark to truly close to the 50% scores point. By now, about half the class understood the concepts reasonably well, scoring above average, and only half the class was attempt and scoring less than average on understanding the concepts. This trend again changed in week 4 where a negative skew showed that now a majority of students had caught up with the concepts being taught in class and only a minority was still scoring low on the scale while the majority was scoring towards the higher side.
