This is for statistics. Find a study that would result in a collection of data that is skewed to the left, bimodal, and uniform.
It is widely claimed that a histogram is skewed to the left when the median is greater than the mean and to the right when the median is less than the mean. But there are exceptions to this claim. Demonstrate this exception by creating a data set that has at least 15 samples and plot the histogram.
