老師您好,
我想請問關於HW1 Question5的問題,
要算attack occurance與population的關係時,
我population用的是 s_df 表格裡的資料,
可是我發現 (s_df裡的state) 比 (計算attack的表格裡的state) 少了兩個,
而老師給的範例答案中,兩種state都是都一樣的。
所以我想問是我用錯表格了嗎?還是我應該要自己找資料補上population所缺少的值呢?

這個資料及的確會有這個問題,
這也是這個作業想要提醒同學的重點之一。
由於網路上的資料常常會有缺漏和不一致,
所以你在做資料清理的時候要留心。
你可以稍微了解一下美國的州名,
然後自己決定要如何把缺失或是對不上的資料做處理,
我們的作業通常不會有標準答案,
只要合理就可以了。
