median statistic 在 陳盈卉 Vivien on Air Facebook 的最佳解答
薪資平均值落在那代表什麼呢?顯然主計總處的調查結果和民眾落差很大,我倒是覺得在這樣的氛圍下,主計處不妨也公佈一下眾數、中位數等等訊息,可能還比較符合現況,還有現在不論那個調查單位還是研究機構,都用了太多、或只用了描述性的統計資料,這些數字意義其實不大,頂多是描述出現況的輪廓而已,為什麼不用高階一點的統計學呢?從大數據中找尋脈絡、歸納,看出趨勢、預測未來才是比較重要的吧!大家加油好嗎!!
主計處新聞稿
https://www.dgbas.gov.tw/ct.asp?xItem=40964&ctNode=5624&mp=1
Our Directorate General of Budget just released latest statistics data which points out that our average monthly income stands at NT$51,241, which obviously "outraged" young and middle majority.
Here is what I think, why not release mean, median and other statistics figures to see how it stands for our current profile? In the meanwhile, this press release also reflects that descriptive statistic alone is not enough, we should, or the leaders, experts, and authorities should be able to generalize and conclude something. Interpretation is the issue, predictions, trends, and find out the context are what we need. Collecting what we have is only where we are now, interpret is the major task. We deserve to know more, so we know where and how we move forward.
