WebThis can be partially avoided with the cut parameter, which specifies how far the curve should extend beyond the extreme datapoints. But this influences only where the curve … WebProblem 2: The graph would be left-skewed since the mean is smaller than the median and hence to the "left". Problem 3: Using similar logic as problem 1, the mode is the peak of the density curve. Since the median is the "middle number" and it's equal to the mode, the mode would also be in the middle of the graph.
