Does better movie (represented by high score) achieve higher box office? Firstly, Pearson and Spearman correlation analysis both output correlation coefficients about 0.5 with a p-value less than 0.05. More factors are influencing the box office. Furthermore, an OLS model was developed to explore this linear relationship. Box office is the dependence variable against average score and year. Year is took as an independent variable because the dollar purchasing power varies through time, which influence the value of the box office. As a result, the r-squared is 0.748; the p-value of score is 0.000278, and the coefficient of score is 4.651e+06. In other word, score and year can mostly explain of the box office. Especially score has significant linear relationship with box office. Most interestingly, the box office increases 4.65 million dollars on average as the score increase 1 (100 in total). In conclusion, in most cases better movies actually (represented by high score) achieve higher box offices among the DC and Marvel movies, but there are more factors influencing the box office.
