Conclusions
[1]. The sig value of this model is less than 0.05, which means this model is statistically effective; [2]. We can use this model to predict whether a person is one of Sports Population or not. The correct rate of this prediction reaches 81%. [3]. The factors influencing sports population are education, occupation, age, sex and city or rural, with their relative importance decreasing from left to right. [4]. The percent of Sports Population in intellectual workers is 2.8 times of that in labor workers; the percent of Sports Population in city residents is 1.5 times of that of rural residents; the percent of Sports Population in people with education degrees above high school is 2.6 times of that of people with education degrees below primary school; the percent of Sports Population in people with university degrees is 2.7 times of that in people with education degrees below primary school; the percent of Sports Population in male is 1.8 times of that in female; the percent of Sports Population in either middle-aged or young people is half of that in senior people.
