微观平均关注单个类别的研究，如企业商品的价格和市场结构；而宏观平均则涉及整体聚合或总量，如失业率、价格水平、经济增长和GDP。当每个类别有相同数量的样本时，微观平均和宏观平均会得出相同的评分。宏观平均对每个类别给予相等权重，微观平均则对每个样本给予相等权重。

直觉解释

Micro average is concerned with the study of individual classes. For example, a firm’s micro average examines personal goods’ price and market structure.
Macro average is concerned with aggregations or totals. We study economy-wide phenomena such as unemployment, price levels, economic growth and gross domestic product or GDP using macro average.
Macro averaging gives equal weights to each category while micro averaging gives equal weight to each sample. If we have the same number of samples for each class, both macro and micro will provide the same score.
