儿童平均每日屏幕时间
该数据集《Average Daily Screen Time for Children》主要用于监督学习任务，数据形态以表格为主。 题目说明：A dataset children's daily screen time habits, categorized by age, ge 任务类型：表格监督学习。 建议流程：先做缺失值/异常值处理与特征编码，再比较逻辑回归、随机森林、XGBoost。 评估建议：使用分层切分或交叉验证，优先关注 F1、Recall、AUC 等分类指标。 可用文件：screen_time.csv。 This datas real - world trends in children's screen time usage. It includes data on educational, recreational, and total screen time for children aged 5 to 15 years, with breakdowns by gender (Male, Female, Other/Prefer not to say) and day type (Weekday, Weekend). The dataset follows expected behavioral patterns: Screen time increases with age (~1.5 hours/day at age 5 to 6+ hours/day at age 15). Recreational screen time dominates, making up 65–80% of total screen time. Weekend screen time is 20–30% higher than weekdays, with a larger increase for teenagers. Slight gender - based variations in recreational screen time.
