实验概率
Experimental probability
记录、描述并分析概率实验中各结果出现的频率,帮助学生理解相对频率可以作为概率的一种估计。
Record, describe, and analyse the frequency of outcomes from probability experiments to develop an understanding of relative frequency as an estimate of probability
学习证据 / Evidence
- 进行抛硬币实验,用频数表记录结果,并计算相对频率
- 将实验结果与理论概率进行比较,并解释差异
- 预测随着试验次数增加,相对频率会趋近于理论概率
- Conduct a coin-toss experiment, record results in a frequency table, and calculate relative frequencies
- Compare experimental results with theoretical probability and explain discrepancies
- Predict that relative frequency approaches theoretical probability as the number of trials increases
评估问题 / Assessment
如果{{name}}掷一个骰子60次并记录结果,他们能否比较每个数字出现的次数与理论上预期的次数,并解释为什么两者可能不完全一致?
If {{name}} rolls a die 60 times and records the results, can they compare how often each number came up with what they'd expect in theory — and explain why they might not match perfectly?
