Skewed quadratic function
WebbQuadratic equations are written in vertex form as: y=a (x-h)^2+k where (h,k) represent the vertex of the parabola, and the sign of a represents if the graph of parabola is open upwards or downwards. In your equation y = - (x-2)^2+3, Vertex (h,k)= (2,-3) Since a=-1, this tells us that the graph will be open downwards.

It takes advantage of the fact that the mean and median are unequal in a skewed distribution. Pearson’s median skewness =. Pearson’s median skewness tells you how many standard deviations separate the mean and median.
Webbdata set is skewed/imbalanced if its dependent variable is asymmetrically distributed. Dealing with skewed data sets has been identified as one of the ten most challenging problems in data mining research.
