The case analyzes factors impacting the market share of brand B1 using statistical analysis in Excel and SPSS. Key factors like average price of B1, distribution, and media spending of B1 and competitors were analyzed. The analysis found that increasing B1's price would decrease its market share due to negative correlations with distribution and sales value. Increasing media spending for B1 and focusing on effectiveness was recommended over decreasing price to maximize market share. The competitive market responds to pricing changes, so B1 needs strategies considering competitors' reactions.
