Three products including moisturizing cream, perfume, and sunscreen were examined using a statistical method. The effect of factors on product sales was predicted using the spline smooth prediction method and based on the predicted values, using the non-parametric Friedman test and Mean Rank, the effective factors were ranked in each of the three products. Moreover, the company’s sales volume in each of the three products was forecasted by using ARIMA models. The results demonstrated that factors such as “price” and “product” elements are the main drivers influencing the sales of moisturizing creams and “promotion” and “Inflation rate” factors play the most effective role in the sales of the perfume. Also, the compound aggregated growth rate (CAGR) for moisturizers, perfumes, and sunscreens over a five-year period in the study company are 30%, 29%, and 45%, respectively.
