Data analysis of subjectivity is statistical inference, which divides the views of the person into categories such as:
One, two, three, and so on are understandable, but counting the number of supporters of an idea is only the first step in statistical inference, and just based on the amount of these raw data (there are more people who support point one, those who support point two are second, and those who support point three are relatively small). Question) is only a general statistical description of the problem and cannot be used as a basis for statistical inference, i.e., conclusions.
The analysis of subjective data,1 divides the views of the people into categories such as:
One, two, three, etc.; (When classifying, minority views should also be listed separately) 2, and the data should be counted separately (the number of counts);
3. According to whether the data population conforms to the normal distribution, the significance hypothesis test of the difference is carried out separately. Yes, tested with parametric hypotheses; discrepancies, tested with non-parametric hypotheses. A significant difference is only true if the difference exceeds the probability at the random level.
before we can draw conclusions. The significance level of hypothesis testing "alpha" is generally taken or.
4. When using graphics to assist the image and clearly illustrate the differences between different points of view, choose a bar chart. Bar charts are mainly used to represent discrete data, i.e., counting data. The bar chart uses the length of the bar to represent the size of the quantity, and it is easy to see the number of various quantities from the bar chart for easy comparison.

For example, 100 subjective test papers.
Each answer will have its own point of view, and there will be repetition in these 100 points. Assuming that there are a total of 3 main points, the data analysis is as follows:
Opinion Proportion--- i.e., people who support that view.
Viewpoint 1 40
Viewpoint II 30
Viewpoint III 20
Other perspectives 10
Other views are those that are confusing or unmainstream or extreme.
Based on the analysis of the data, the conclusions are:
There are more people who support the first point of view, which means that ... Issue.
Those who support point 2 are second, which means ... Issue.
There are relatively few people who support point three, which shows that ... Issue.
Other points of view are briefly reviewed.

Hui Research (professional third-party market research service provider).
First of all, let's talk about the importance of writing a good data analysis report, which is very simple, because the output of the analysis report is the result of your entire analysis process, the qualitative conclusion of evaluating a product and an operational event, and it is likely to be the reference basis for product decision-making.
First of all, have a good framework.
Like building a house, a good analysis must have a foundation and a solid foundation, and the level is clear to make the reader clear at a glance, and the structure is clear and the priorities are clear to make it easy for others to read, so that people have the desire to read;
Second, every analysis has a conclusion, and the conclusion must be clear.
If there is no clear conclusion, then the analysis is not called analysis, and it loses its own meaning, because you are going to find or confirm a conclusion before you do analysis, so don't forget the original fruit;
Third, the analysis conclusions should not be too many and precise.
If you can, an analysis of the most important conclusion is good, many times the analysis is to find problems, if one by one analysis can find a major problem, it will achieve the goal, do not seek more for everything, rather than a bite of peaches, not a basket of rotten apricots, the concise conclusion is also easy for the reader to accept, reduce the important reader (usually a leader with a lot of affairs, not too much time to see so much) reading psychological threshold, if others see too many problems, the conclusion is too complicated, do not read on, a hundred conclusions are equal to 0;
Fourth, the analysis conclusion must be based on the closely forbidden data analysis and derivation process.
Don't have speculative conclusions, things that are too subjective will not be convincing, and if a conclusion is not even sure of yourself, don't take it out to mislead others;
Fifth, a good analysis should be highly readable.
This refers to legibility, everyone has their own reading habits and ways of thinking, you will always write according to your own thinking logic, you yourself feel very clear, that's because the whole analysis process is done by you, others may not know so much, you must know that readers often only spend less than 10 minutes to read, so you have to consider who your analysis reader is? What do they care about most? You have to put yourself in the reader's shoes to write an analytical email;
Sixth, the data analysis report should be as graphical as possible.
This is actually a supplement to the fourth point, using charts instead of a large number of stacked numbers will help people to see the problem and conclusion more vividly and intuitively, of course, there are not too many charts, too many charts will also make people confused;
Seventh, a good analysis report must be logical.
Usually it is necessary to follow: 1. Find the problem 2, summarize the cause of the problem 3, solve the problem, such a process, and a logical analysis report.

SC-CPDA Data Analysis Public Communication Platform View my profile for details.
Weibo data analysis can be deep or shallow, and if you want to speculate on the blogger's business strategy, you need to track the data for a period of time, and the minimum time is a week. Weibo to implement the real-name system, this initiative has a great effect on the healthy development of Weibo, network culture is valued, Weibo marketing is bound to receive more and more attention, the data analysis of Weibo is conducive to us to better do Weibo, so what is the specific collection of Weibo data? What can be seen in the data?
1 Fans: From the perspective of fans, people with a large number of fans can naturally attract people's attention, if the growth is fast, what can it mean?
2 Content: Judging from the blogger's Weibo content, what type of Weibo is it? Is it purely original, or is it an activity such as voting, with a prize**?
How often do bloggers post content every day? The ** of Weibo content, is it original product information or all kinds of sharing, or is it from the PP content library?
4 Attention: From the perspective of attention, what people and industries do bloggers follow, and whether they are in the same industry? Among the people who are concerned, are there many people who add V certification? What does a lot of words say?
After the collection of the above data, it is not difficult to see that the main strategy of bloggers is to increase the number of microblogs to increase the influence of microblogs. So how to increase the number of microblogs, the most important thing is the content of microblogging, judging from the collected data, the content of the activity is often very high, generally there are hundreds. For example:
**Entry Weibo and @3 friends, you will have a chance to win prizes. What's more, the blogger will put a certain Weibo at the top, then the number of this Weibo will naturally increase.
What does a Weibo private message do? Most corporate microblogs have a private message function. The author thinks it would be better to have a private message function.
Private messages are very good for the interaction between bloggers and netizens, and the new version of Weibo's private messages have a section similar to the chat window, which is very convenient for those who have used it. It doesn't have to be @who, @之后的语句是所有人都可见的 to communicate with netizens, and private messages are private. As a blogger with hundreds of thousands of followers, when you have a conversation with a very ordinary fan, the fans will be very happy to interact.
This increases the stickiness and loyalty of fans.
The development of Weibo is favored by many people, especially after the real-name system, analyzing the opponent's Weibo or the top Weibo will help us gain a firm foothold in the Weibo trend.

5. Help enterprises to carry out services.
Through big data computing, social information data, customer interaction data, etc., can help enterprises to carry out the horizontal design and fragmentation of brand information. Economist Richard H
Thaler once argued that "a small change in an individual's perspective can turn into a major change in the pattern of group behavior for all." "In the context of this major change, for the tiny flow of information, enterprises are.
It has to be taken seriously, and customer service needs to be like air in the minutiae in order to cope with this situation. Enterprises can use the massive data disclosed in social networking to cross-verify technology and score through big data information.
Do you understand these five roles of big data? How to make good use of big data can start with its five functions.

At present, the leader in data analysis in China is FineBI, and multi-dimensional OLAP analysis is the concentrated embodiment of the analysis function of BI tools, and its application characteristics are mainly reflected in two aspects: one is the real-time query effect (online), which requires the calculation speed of background data and the display speed of the front-end browser to be very fast; The second is multi-dimensional custom analysis, which requires that the multi-dimensional database of BI tools should have greater flexibility and can combine arbitrary indicators and dimensions according to user requirements. Only the interactive analysis process that satisfies these two characteristics at the same time is multi-dimensional OLAP analysis, which can ensure that users can see the statistical results corresponding to their analysis needs in real time, and meet the new analysis needs generated immediately according to the results of the previous step by switching dimensions and changing conditions.
The subdivision method can be divided into two categories, one is step-by-step analysis, for example: visitors to Beijing can be divided into Chaoyang, Haidian and other districts; The other type is dimensional crossing, such as new visitors from paid SEMs. >>>More
For most manufacturing enterprises, the automatic data acquisition of measuring instruments has always been a troublesome thing, even if the instrument has RS232 485 and other interfaces, but still in the use of measurement, while manually recording to the paper, and finally input into the PC to process the way, not only the work is heavy, but also can not ensure the accuracy of the data, often the data obtained by the management personnel has been lagging behind the data for a day or two; For on-site defective product information and related output data, how to achieve efficient, concise and real-time data collection is a major problem.
