If 3 of the students who scored below 140 decide to drop the class what would be the shape of the distribution?
Well, honey, if 3 students who scored below 140 drop the class, the distribution would likely become more positively skewed. Those low scores dragging down the left tail would be gone, making the remaining scores bunch up more towards the middle and higher end. So, you might see a shift towards a more normal or even slightly right-skewed distribution.

Write a statement about each class that explains the median tells you?
The median is the middle value in a dataset, providing a measure of central tendency that is less affected by outliers than the mean. In each class, the median indicates the typical performance or characteristic of the students, helping to identify the point at which half the students scored below and half scored above. This can highlight differences in achievement levels across classes and reveal whether the majority of students are performing at, above, or below the expected standard. Overall, the median serves as a robust indicator of the overall class performance.
What percentile is 432 on mat exam?
