About the iPhone and Android mobile phone number that something

In the text before the start of the first, to an arithmetic question it. Conditions 1-a person to the number of students in statistics, sampled a some primary school within the 500 students, random spot check; The men and women get ratio is the USA.

Condition 2-from school file to understand, at present the school boys were 400.

Question 1: this school about how many students are there altogether?

Question 2: how many girls?

Question 3: how many people are only children, how many are not?

If simple point to, the first two asked is actually a primary school in arithmetic. Total students is 400/55% * 100% = 727 (number, take integer), total girl is 727-400 = 327. The third asked is pure 2 B, don't explain, god knows how many. (if deep into the principles of statistics on consideration, the randomness, and 1 conditions is the 500 samples is in accordance with the statistics requirements will become very important. If this random is not entirely in the sense of random distribution, the result may deviation, but the deviation of range have how old? In a total of 727 sample space is in 57 500 samples, 68.8% coverage, hobbies, and remember to ask investigation of the high number of knowledge for let students deviation.)

7.27 million iPhone, 3.27 million is unicom. There are many gray, and how much of the problem of HangHuo as the above problem 3, root no relation, known conditions and the no any relation! Meanwhile, more than 700 iPhone just last month, the number and GMIC simultaneously on XiongJun CEO network data released by the agreement.

The iPhone has calculated, we come to see Android. I find that I am still not the tragedy find very direct data, I can only through a lateral data to calculate.

Data 1:1 month issued a union of Android report, covering domestic 4 million Androdi terminal, at that time, 50% coverage. The report addresses: 

Data 2: the whole world activated Android device of 100 million, day activation of 400000, three months after activation number is 350000. Source: May 10 Google I/O assembly published data;

Data 3: Gartner statistics, the 25 th global smartphone shipments of 101 million, of which nearly 36%-35.7 million of Android, the asia-pacific region than 37% of shipment.

How to calculate? These data can be roughly how China's data get? From the data 3 roughly calculated, 1.01 * * * * * 36% 37% = 13.45 million this is about 11 years in the 25 th the asia-pacific region Android mobile phone number. Also is 11 years in the 25 th every month of the asia-pacific region about Android at around 4.5 million according to the asia-pacific region, and always mentioned, is it which countries, I especially under the baidu, get the results are as follows: in a narrow sense, refers to the western Pacific region, mainly including the east China (including Hong Kong, Macao and Taiwan), Japan, Russia's far east and southeast Asia the asean countries, sometimes also extended to Australia and New Zealand and other countries.

Mainland China accounts for how much here? Who knows? Who can tell me? I clap his head bold hypothesis is a third, that also is domestic new Android phone 1.5 million every month. Over the past five months at the eye, the za computing to the end of may, the new total 7.5 million, is at the beginning of the year 8 million on the stock, so total is 15.5 million!

Many people see here will have many questions.

Doubt 1: a friend of the union is accurate data? Why a lot of people said that 10 years end China's only had about 5 million Android terminal;

Question 2: China accounts for one-third of the asia-pacific region is too radical? Almost a quarter? Even 1/5;

Question 3: you directly by the count is so too rough point?

The truth solid say this is my question, but in the present data base case I can only computing to this point. Change several conditions, with a little pessimistic way again calculate to:

If the end of 10 years China's domestic stock Android is 5 million, if China accounts for only a quarter in the asia-pacific region, and the amount is 500 + 450/4 * 5 = 10.625 million. Not to forget it, probably of the order of magnitude of basic sure, around 1000-15 million-ship on each between 110-1.5 million, plus original 10 years of stock is total. As for what everyone choose MAX or MIN, all by intuition.

Finally, add a gossip data as end: tencent friend said there are about 15 million QQ number in Android devices accessed a (not guarantee that the data accuracy). How to calculate the total Android phone? Both want to understand as a number, on average every device a few QQ number (1.2 1.5 1.8???) , the mobile phone in Android mobile phone coverage of the QQ (60%, 70%, 80%)?

I also does not calculate, the more a few people want to it.

Actually write about the domestic mobile intelligent terminals this thing, I have said for 2 years. This should be the last time I write this article, as to the next, iPhone and Android mobile phone orders of magnitude will is big enough, the terminal of the quantity, penetration rate has enough market for you to do anything, wopad m12 builtin 3g so next year to discuss the number of terminals have no meaning. As of early that year CNNIC data statistics report also said China how many Internet equipment, and today? Who is concerned about China's how many computer can connect to the Internet? Similarly.
