Answer #1

when the bell curve is skewed to one side ,it means that there are some extremely high or extremely low values observed in the distribution which falls far from from the usual range of data values. These extreme values stetches the bell curve to one side.

To counteract this problem we can choose higher sample size. Higher sample size it reduces the variation or variance in the data. Which leads to the most of the data falls in the centre only & it looks like perfect bell curve.

Some teachers grade on a "(bell) curve" based on the belief that classroom test scores are normally distributed. One way of doing this is to assign a "C" to all scores within 1 standard deviation of the mean. The teacher then assigns a "B" to all scores between 1 and 2 standard deviations above the mean and an "A" to all scores more than 2 standard deviations above the mean, and uses symmetry to define the regions for "D" and...
