Is it possible for the 25th student in a class of 49 students to score higher than the average?

How is it impossible, the scores of 26th place and beyond are very low, let's say they are all zero.

It is possible that the average score is the sum of all the scores divided by 49. Assuming that the difference in range is too large, it is possible for the twenty-fifth place to be higher than the average score For example, three people 100 75 5 add up to 180 and the second place is completely higher than the average score of 60.

It's possible. However, I can't imagine how low the last person was.

It is very likely to be higher than the class average, or it is possible to be lower than the class average, and the most important thing is how many points you get.

There are 49 students in a class, and the 25th student may have a higher score than the average score.

The results of the college entrance examination have been announced, and the students who did well in the exam are busy filling in the volunteers, and the students who did not do well in the exam are already preparing for review. Under normal circumstances, students in the same class, there will always be someone who does well in the test and someone who does badly, but in this year's college entrance examination, among the candidates in Jiangsu, there is such a strongest class, and the 49 students in the class all collectively rushed through the first line and achieved the "grand slam" of one line. Such results are very rare in Jiangsu Province, which is known as the most difficult province in the college entrance examination.

Seeing this news, many netizens immediately sighed and wanted to be classmates with them, but unfortunately they only blamed themselves for not choosing the right class at the beginning.

The full score of the 2019 Jiangsu Provincial College Entrance Examination is 480 points. Jiangsu's first line of science is 345 points. In the 13th class of the third year of high school in Fengxian Middle School, Jiangsu Province, when the results of the college entrance examination were announced, after the whole class checked the results, everyone found that everyone was on the line.

There are a total of 49 people in this class, that is, 49 people do not fall behind and collectively rush through the line. Such excellent results made the Chinese teacher and class teacher of this class, Ms. Ma Yulan, very happy.

When many netizens saw this, they began to feel very lost, if I was also studying in this class, would I also be able to achieve a book online? In fact, the thoughts of some netizens really have a certain truth, the reason why your academic performance cannot be improved, in addition to your own talent and hard work, is also closely related to what kind of learning atmosphere you are in. If you are in a class, every student strives to improve, the learning atmosphere in the class is very good, and the classmates are both competitive and cooperative, everyone cheers each other up and competes with each other, and in such a learning atmosphere, everyone is easy to make progress.

In contrast, if you are in a class, the style of study is sloppy, there are few top students in the whole class, everyone has no confidence in going to college, and there is no confidence in getting good results in the college entrance examination. This is the so-called red near Zhu and black near ink. Therefore, if we are always with those students who strive for improvement, over time, we will also be influenced by them, and we will actively pursue progress.

Of course, the reason why the students of this senior class have achieved such good results is that each of them is particularly hard working and working hard, if you only see their class as a whole through a line, and do not see the hard work and sweat of the students, just think that they are all people with special luck, such an idea is also biased. There is a good learning atmosphere, but if you don't care and don't work hard, you are very likely to become the person who drags your feet, what do you think about this?

Such a result should be around 20th. If you want your child to learn ability, parents must pay attention to the education method:

Cultivating students' interest in learning:

The most effective motivation for students to devote themselves to learning is not the supervision of parents, but the students' interest in learning itself. Once learning is regarded as a task, children will inevitably suffer more in the learning process.

Help your child develop study habits:

Primary school children establish the concept of learning, the most critical period, if the child can develop good learning habits at this time, then will benefit immensely in the future learning process, master the management of time, improve learning efficiency, can help children better complete the learning task.

Parents do not show excessive anxiety:

In the process of paying attention to students' academic performance and counseling, parents should not instill too many negative emotions in their children, although students need a certain sense of urgency, but the learning pressure is too great, it is very easy to affect the physical and mental health of children, as long as the grades are not left behind.

One class is four people with an average score of 89.

One student scored 90 points.

Such a result should be around 20th.

It can only be an approximate number.

Hello! This is difficult to infer from calculated data.

Because of the uncertainty of the score gap between students, we can only roughly estimate that 90 points are not much different from the average score of 89, and this student should be ranked around the middle, that is, about 27.

Summary. There are 45 students in the class, with an average score of 264, a total score, and a required score greater than the average score of 17 points. First, calculate the total score for the entire class:

264 points * 45 people = 11880 points. Then, the deviation score is calculated: Total score score - 11880 points = points.

Since the deviation score is negative, the total score is less than the average score. This may be due to an error in the total score data. If the total score is the correct score, then there is an inconsistency between the average score and the total score.

There are 45 students in a class, and the score is 17 points greater than the average score, which is the approximate ranking.

The average score is 264, and the total number of people is 45, and we have a total score.

How many places can you rank?

Why don't you speak.

Kiss, the class has 45 people in the chain, the average score is 264, the total score, the score is required to be greater than the average score of 17 points. First, calculate the total score for the entire class: 264 points * 45 people = 11880 points.

Then, the deviation score is calculated: Total score score - 11880 points = points. Since the deviation score is negative, it means that the total score is less than the average score.

This may be due to an error in the total score data. If the total score is the correct score, then there is an inconsistency between the average score and the total score.

First, calculate the total score for the entire class: an average score of 264 out of 45 = 11880 points. Then, calculate the difference between your score and your average score:

Score - 264 = Points. Next, calculate the percentage ranking of your class based on the difference between your score and your average score. To do this, we can divide the difference between your score and the average score by the standard deviation of the score difference, and then multiply the result by 100.

Please note that the calculation of the standard deviation requires knowing the specific score of each student. If a score for each student is not provided, we cannot accurately calculate the ranking percentage. However, if we assume that the score distribution conforms to a normal distribution (mean 264, standard deviation standard, no actual data is provided), the rule of normal distribution can be used to estimate it.

In the normal distribution, about 68% of the data are within one standard deviation of the mean, about 95% are within two standard deviations, and about three standard deviations are within the range of three standard deviations. This is only a rough estimate, given the lack of specific data. Let's say your score is equal to the average plus one standard deviation (points):

264 points + points = points. In this case, your score is estimated to rank in the top 68% of about 68% of students. If your score is equivalent to the average score plus two standard deviations:

264 points + 2 * points = 297 points. In this case, your cheat clearance score is estimated to rank in the top 95% of about 95% of students

There is a student in this class.

If all boys are assumed, then the average score of the whole class is that the total average score will increase for each buried boy to one girl ( (If all girls are assumed, the total average score of each girl will be reduced by the same number for each girl who is replaced by a boy). For the sake of convenience can a be used in place of this number, then.

Summary. Extended information: Average, a statistical term, is the amount of trends in a set of data, which is the sum of all the data in a set of data divided by the number of data in that group.

It is a metric that reflects trends in a data set. The key to solving the average problem is to determine the "total quantity" and the total number of copies corresponding to the total quantity. In statistical work, the mean (mean) and standard deviation are the two most important measures to describe the tendency and dispersion of a data set.

There are 46 people in the class, 11 points less than the average score, which is about what the ranking.

Kiss is happy to solve the problem for you: there are 46 people in the class, 11 points less than the average, about 34.

Qinqin Douliang: The answer process is as follows: the average noisy score is the middle score, 46 2 = 23 people 1 point one person is: 23 + 11 = 34 people so: the ranking is about 34.

You're too slow.

Kiss: It takes time to do the question, people are not machines, and the results can be produced at once, I hope you can understand, the answer will be sent to you in front, pay attention to my news.

Qinqin Douliang: The answer process is as follows: the average noisy score is the middle score, 46 2 = 23 people 1 point one person is: 23 + 11 = 34 people so: the ranking is about 34.

Summary. There are 44 students in the class who are ranked second, so what is the percentage of place in the class?

He's in the top 10 percent.

What kind of exam is this? Average per person:

34 50 = points.

34 50 = points.

A: Average points per person.

Although the equation is true, it is clearly not in line with the actual situation, and there is no test with a total score of 34 in the class.
