由一组@statisticmethod函数组成的类的设计

class StatisticCalculator:
    def __init__(self, data):
        self.data = data

    def mean(self):
        # 计算均值
        pass

    def median(self):
        # 计算中位数
        pass

    def mode(self):
        # 计算众数
        pass

    def standard_deviation(self):
        # 计算标准差
        pass

    # 其他统计方法...

# 创建对象并使用统计方法
data = [1, 2, 3, 4, 5]
calculator = StatisticCalculator(data)
mean_value = calculator.mean()
median_value = calculator.median()
mode_value = calculator.mode()
std_deviation_value = calculator.standard_deviation()
