A businessman has a two-year gross monthly sales of 1200; in Year 1, months 1-6, sales increase 5%; in months 7-12, sales decreased by 2%; in Year 2, months 1-3, sales increase by 1%, months 4-6 sales increase 3%, months 7-12 sales decrease 2%. How would this be shown as a bell curve? A positive or negative skewness. Trying to understand if sales revenue increases, is this considered a negative, and if they decrease, is this a positive?
