Marketing Analysis 市场分析案例 In the first step, we would like to select the raw data for the three brands such that two are of the same price category (high or low), and the third is of the other type. It was essential to make sure the package size (QTY, indicates the size of the bundle) is the same for all three brands. So, we divided the data for high-movement sport drinks into two subsets by QTY=1 and QTY=2. Then, for each subset, we used pivot tables to find average prices for the brands for Feat = 0 and Feat = 1, and total counts of cases. Filtered by the sizes of 20OZ, 32OZ, and 64OZ, the pivot tables for QTY=1 subset are shown in the following figures. https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/43400dd1-f93f-48c4-9b60-0a9624bedcb4/653+01.png Work - Marketing Analysis 市场分析案例 - Q1: How does the demand for a brand depend on price? What is the price elasticity of demand of a brand? Is price elasticity different for different brands? According to the calculations, The price elasticity respectively for ASLL, PFP, and ASFP are -1.925382, -2.981695, -1.925382. Therefore, we conclude that as the price of a brand goes up, the demand drops. The price elasticity is different for each brand. https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/9c5c8899-d9f0-4f6d-824a-5442768502eb/653+02.png Work - Marketing Analysis 市场分析案例 - Q2: What brand and what season have the highest probability of being on sale? The probability of being on sale is different for each season and brand. The highest probability for a brand on sale is during the winter. Spring is the second highest season to most likely be on sale, Fall is the third most likely season to be on sale and the least likely season to be on sale is Summer. Example of one of the calculation: Brand: ASFP Dummy Variables: ASFP=1, ASLL=0, PFP=0 I= 0.57927 -0.03786(ASLL)-0.32430(PFP)-0.05008(Spring)+0.22334(Summer)-0.22437(Winter) = 0.57927-0.05008(Spring)+0.22334(Summer)-0.22437(Winter)= 0.52186 https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/6ea806d0-e438-4c8b-a89d-4d8826ecf2d1/653+03.png Work - Marketing Analysis 市场分析案例 - Q3: Determine if ASLL and PFP are equally likely to be on sale at 99% confidence. Since the p-value is less than 0.01, we can reject the null hypothesis at 99% confidence. https://becaqian.com/portfolio/blockchain-in-advertising- monthly 0.5 2022-04-13 https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/724a191f-f750-4dc2-8ebe-967bc4afd258/Screen+Shot+2022-04-13+at+11.28.01+AM.png Work - Blockchain in Advertising 区块链在广告中的应用 3 pain points in marketing and adverting https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/2e293a76-bd61-4d10-97da-54fad0e951a4/Screen+Shot+2022-04-13+at+11.32.06+AM.png Work - Blockchain in Advertising 区块链在广告中的应用 https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/67c16058-7511-46f0-bec0-de472ab53f9b/Screen+Shot+2022-04-13+at+11.32.51+AM.png Work - Blockchain in Advertising 区块链在广告中的应用 https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/41a376a3-4ff8-429d-bb00-68ba112512d5/Screen+Shot+2022-04-13+at+11.33.16+AM.png Work - Blockchain in Advertising 区块链在广告中的应用 https://becaqian.com/portfolio/project-two-nzxxc monthly 0.5 2022-04-12 https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/d9539b41-0cf5-47e0-96ef-aacebe1a6587/Picture1.png Work - Machine Learning机器学习 - Make it stand out DATA INFO https://images.squarespace-cdn.com/content/v1/5e82071b6ab6a703525dba4e/c1862227-f3d9-4549-89fb-7f07f2913f12/Screen+Shot+2022-04-12+at+6.34.56+PM.png Work - Machine Learning机器学习 - Conversion Rate Color represent whether a conversion is made, which also means whether a consumer make a purchase.
