Application of Statistics and Probability PPT, Part 3: Lecture and Practice Interaction

Application of Statistics in Decision Making

On April 20, 2019, the Fujian Provincial People's Government announced the "3+1+2" new college entrance examination plan. The "2" in the plan refers to choosing two of the four subjects of ideological and political, geography, chemistry, and biology. The single subject score recorded in "2" as the total score of the college entrance examination is the grade score converted from the original score. The higher the original score of the subject college entrance examination in the province, the higher the grade score. Xiao Ming is a freshman in high school in 2018. It has been determined that geography must be chosen and politics will not be chosen. In order to determine another subject, Xiao Ming collected and sorted out the score percentage ranking data , candidates with higher scores than Xiao Ming accounted for 19% of the candidates who took the exam). Draw a stem-and-leaf diagram as follows.

regular method

The decision-making thinking in statistical problems mainly uses numerical features and frequency distributions to predict and estimate some practical problems. However, we cannot rely on single numerical features for estimation, but instead combine various factors to make reasonable explanations and judgments.
