Looking at Rogue data traps from "the old confused"

In the early summer of the last century 90 's, the breeze was blowing and the cicada kept chirping. In the campus, each classroom has heard the rustle of Voices, a title of three students are in the middle of the tour. In the last row of the classroom, a comely girl with a ponytail passed a note to the boy next to it, saying, "I heard the cinema is playing Titanic today," and we skipped class to see it! ”

Boy saw the note, the face suffused with a faint blush, a face excited to return a note, "I heard that the people's Street video Hall today put the latest" ancient confused son "Ah, we go to see that bar. That night, the man and a woman in the boy's insistence, or went to see the "Ancient confused". From the next day, the girl began to yell at him "brother".      Two humans never again.       Many times, if the phenomenon can not see through the essence, it will certainly fall very miserably, chasing girls is so, playing the data is the same. The different angles of reading the data from the priest

the same person, in the eyes of other different people's image is strange, it is difficult to do uniform. The same picture, the same data, are quietly in situ, different angles will bring different effects.       For example, the same Taobao clothing, the effect of the monitor and receive the goods after the effect is difficult to maintain consistent, as shown in the body of the figure colleagues. For example, in the old man's hand-shading, Father Lin on the court to stand up to face the Crow, command killed dozens of armed with a kitchen knife mop neighbor, said his classic lines, "I preach more than 20 years, so that everyone believe that Jesus will not necessarily, but let everyone chop people they will comply." ”

So take this scene and freeze it. Different media If you give this scene a title, "Reader" must be "the priest behind the philosophy of the small story", "bosom friend" must be "thick big love ah for that, Junya priest for the juvenile to prop up a day", the legal version must be "control when the tool ban?"   24 machetes have been discovered in Peace Street, and the street tabloids on the subway must be "The Beast Priest shows the real fangs command to wash the dongxing". Data is dead, man is alive.       It will be a necessary skill to learn how to interpret rationally, especially for workers like me, who must learn to find the most useful reading point of the data. Two, from the big day two is overcast to look at the data the first condition

  Big day two in the first three of the ancient puzzle has not been the Mountain Dew, and the actor Xietianhua in the year was also just a junior. But at the beginning of the fourth episode, when Fei put his sister to marry him, his status within the hongxing soaring, it is this status change, let him ready to help pheasant Tunmen carry the Visigoths, failed to calmly analyze the data.   When the insider told him Visigoths every day in the fish booth playing mahjong around only three or four people, the big day two did not from multiple channels to verify the accuracy of data, but heroic with four people will go to fix Visigoths, although before the departure worship Guan, but don't forget, Guan was also because of ignoring the riverside Beacon intelligence network and was cut head.       Visigoths side really only three people with him play mahjong, but the room next to more than 50 people sprang up, two people were pressed in the pool to pick up the hamstring, if not big fly, that night he has been dead on the street.       So, for people who study data, the right data is more useful than a lot of data. The correct here, not only refers to the correct conclusion, but also the correct sampling, the analysis of the correct direction.       In 2013, big Data became the hottest word in the IT world, and no company could walk in the industry without saying that it would be a big data analyst. However, if blindly pursue the large amount of data, and ignore the data of the right, then it is easy to go the wrong way farther.       In a variety of data-statistics textbooks, one case is repeatedly mentioned, that is, when Roosevelt ran for president, the famous American Journal Literature Digest released 10 million reader questionnaires, and did a lot of telephone research, finally concluded that the Republican rand will be 57 % of the 43% 's absolute dominance over Democratic Roosevelt. The final result was Roosevelt's re-election with a 62% approval rating, giving the literary digest a slap in the face.   In this case, is it because the number of samples is not enough? 10 million surveys have been issued and 2.4 million data have been recycled, and the same amount of data is today a huge one. The core problem is that there is an unconscious bias in the choice of samples, and the 10 million Literature Digest reader does not represent the characteristics of all Americans, and the 2.4 million people who are willing to participate in the survey have no similarity to the remaining 7.6 million.     From this we can see that the larger the number of sample data analysis, if there are deviations, the greater the harm caused. For example, if in 100,000 of the customers arrested by the police station to do a survey, asked whether China should open up the sex trade, then the last possible media out of the title is "Human Nature call Liberation, 99% of Chinese people strive to legalize sex transactions."       The precise demand of data analysis from wrapping to be induced by color       

  in Big day two hide up injured, Dongxing Crow under the four eyes in order to find the whereabouts of two big days, sent their plump yellow hair small too sister to color lure wrapping, this trick is called precision. Because if he sent hundreds of people to inquire about the street, low cost and easy to arouse suspicion, if to seduce Chen Haonan Pheasant, they do not see this big chest and no brain of the vulgar little sister. And the foreskin? It is the best breakthrough point to be able to reach the core of information of the two big days.   This is before you start doing any data analysis, be sure to know what you want most, to get the results you want, what data is required, and not to extend the dimension blindly, which will only confuse the results.   Whether for a Web site or for an application, there will be a lot of data indicators, first want to know which of their most important indicators, and then look at the strong correlation with this indicator of which data, and finally come to the conclusion and Operation plan. For example, for the site, the boss is most concerned about the UV data, then in the plan to pay attention to the flow of the largest importer, SEO keywords, third-party platform share. If the boss is most concerned about PV data, then the operation needs to pay attention to the number of users browsing pages, user stay time, user's two jump page and so on.       Iv. I'm not teaching you a scam. Data trap   In many people's eyes, the data is the most impartial and the most objective and the most honest, anxious to elevate the data to the point of worship. But the data is actually a work partner, good data is the same as God's teammates, bad data is a pig-like teammates. There is no right or wrong in the analysis of data, only the appropriate and unreasonable. (in the case of basic mathematical correctness)       in 2011 and 2012, Georgia has announced 65 allegations of 35 educators in Atlanta, most of whom are principals and grade directors. The charges are mainly focused on cheating in exams. Because Atlanta from 2005 onwards, the student's achievement has the ladder progress, at first all all praised the newly appointed education director efficient.       But later, when the State Department of Education was doing statistics, it suddenly found that the proportion of Atlanta students ' answers was far greater than that of students elsewhere. To know from the probability, a student's answer because it suddenly through the two veins, from the wrong change is still a bit possible, but if a test room students altered traces are all the wrong change to correct, this probability is negligible.   began with this anomaly, which cracked the world's gaping test-fraud case for Atlanta. The most heinous thing is that a group of teachers held a pizza party after the exam, and at the party all the students did the wrong questions.became right.   This is the education industry's conscience!!!   Now more and more data, traps are more and more, sometimes playing the word game can make the performance look tall. I have a QQ group, group of a total of three men, one day this year, a tyrants friend to his wife bought a birthday gift, is a Porsche SUV, worth 1.2 million. Later, I said to my wife: "In this group, each man on average this year to his wife's birthday gift value of 400,000 yuan, what are you dissatisfied with?" "That day, the frying pan at home came in handy.       Once an application has been run by a classmate who wrote a weekly newspaper, "after a week of operation promotion, the download volume of this application has been increased by 100%". I looked at the feelings of their worship, this is the tide! Later, he said to me after drinking: "In fact, I have to download the amount from the previous 25 to 50." "Suddenly, I understand, originally he just in a small QQ group to promote a bit." This shows that drinking is harmful to health.       In addition to word games, the production process behind the data is often a trap. For example, a high school science class, there are a total of 10 girls, the average cup is B, while in the sophomore year, inside a cup of girls transferred, the average Cup into C. So from the data, we can come to the conclusion that "from the B Cup to the C Cup, high school learning is conducive to the formation of girls ' body."       Similarly, the dwarf went out, the average height was raised, the poor students went out, the average score increased. So in the future when you see any data, please do not immediately cheer or dejected, think first, the data is reasonable?       V. I'm not teaching you to cheat. Chart Trap
