2.3 measuring the position of the data. When we reached the klang General position or rank of a set of data, such as in the International Mathematical Olympiad, international race summaries are often summarized by the order in which each country has been. In the lower reaches of the country holding the position of any one country. Without other information comprises The message recipients are not able to know whether the position mentioned in the section of the data, which will make it impossible to conclude that points in a good position, or in the year 2546, country Thailand has sent a team of students to participate in international competition, International Mathematical Olympiad, advanced.Japan, the country that at 46 points, including a team in the competition this time is equal to 111 points and is rated at 19, when sorted in descending score, if you don't know what countries participating the tournament this time, few countries will not know the total score of the team from the country of Thailand is in a good position?

Also, to check ร่ช่วย, discussed possible positions for an maiklao is able to tell immediately whether or not the position is good, it's just how the Group has developed a method to locate by using the tile so the percentages have to say the following: Percent tile (Percentile). When you import data into a set of data values in ascending order. The percentage value of the tile as a data point, the sort that 99 ascending into 100 sections, each section contains a number of data is equally known as the percentage so that the tile tile percent 65 (P65) is the number of data values less than this value are approximately six hundred and fifty in number, all the information.
