Re: 九龍塘宣道幼稚園2006K1家長請進
tommyzoe,
So how to apply your plan to this case !?
If it is not applicable, is the previous simple counting method a plactical way to do so?
Do you agree with my forecast that some pm girls will move to am? If not, I would like to see the outcome to evaluate my estimation.
Anyway, I think you have a very strong theoretical background, but my interesting is to have a casual or even 八掛 talking in the Kindergarten topic. Maybe let us do the strict statistical analysis in another topics.

Sampling Inspection is not done in this way. Sampling Inspection is the technique of performing the functions of inspection by examining some of the articles.
Since acceptance sampling contains two different types of data, two different sampling plans can be created. All attribute sampling plans are based on data that can be counted. In attribute plans, a sample is taken from a lot with each unit classified as acceptable or defective. The number of defects is then compared to a specified acceptance number, in order to make an accept or reject decision for the lot.
Examples of acceptance plans are MIL-STD-105 (ANSI/ASQC Z1.4), MIL-STD-1235(ORD) and Dodge-Romig Tables.
In variable sampling plans, a sample is taken and one or more quality characteristic measurements are made on each unit. From these measurements, the sample average or standard deviation is developed to be compared against a critical value defined in the plan. Based upon the comparison, a decision is made to accept or reject the lot.
Examples of variable sampling plans are MIL-STD-414 (ANSI/ASQC Z1.9).
This is for your reference.

呢個係统計學上嘅一個隨機抽樣方式,正如某某競選前嘅預測都不可能找所有選民分析,只有抽樣。首先我假設am或pm嘅家長無理由有上或唔上bk嘅偏向,男生或女生嘅家長亦然。
雖然依家sample size唔算多,但已看到一種不尋常的趨向。這簡單嘅統計之前曾發現am少過pm好多而am,pm班是一樣,便已預計有很多pm會轉到am,結果發生了直至am數=pm數,但近期pm又出奇的多起來,故相信是宣幼再收備取生到pm,之後再接受pm轉am嘅申請。
至於男女生問題係我相信宣幼希望am & pm都有一定女生。
無可否認這始終是統計分析,最終結果也不能說實。
但到底結果是否如此,大家姑且拭目以待。

Why do you always assume that all parents must join BK?

點解pm多過am禁多?如果06真係有2班am & 2班pm,我估差不多會有20%,相信會是女生從pm轉到am。
