We are glad to answer that the average score of the statistics test for this class is 68 points, which is calculated by adding all the scores and dividing by 5, which is 80 + 70 + 60 + 60 + 60 5 = 68 points.

Now give the statistics test scores of 5 students in a class. The data is as follows: 80 + 70 + 60 + 60 + 60 try to calculate: the.

We are happy to answer for you that the average score of the class's statistical test is 68 points, which is calculated as follows: add all the scores, and then divide by 5, that is, 80 + 70 + 60 + 60 + 60 5 = 68 points.

1. The median score of the statistics test in this class is 60 points, because there are 2 60 points, and the two sides are divided into different points and evenly distributed, and the middle is 60 points. 2. The mode of the statistics test in this class is 60 points, because there are 3 points out of 60, which is the most among all scores.

3. The maximum score of the statistics test in this class is 80 points, and the minimum score is 60 points. <>

Summary. Mean: 1 5x(80+70+60+60+60)=66 The median is 60, and the mode is 60 variance:

1 5x((80-66) 2+(70-66) 2+(60-66) 2x3=64 standard deviations: root number (1 5x(((80-66) 2+(70-66) 2+(60-66) 2x3)=8

Now give the statistics test scores of 5 students in a class. The data is as follows: +80, 70, 60, 60, 60 + trial calculation:

Average: 1 5x(80+70+60+60+60)=66 median is 60, and the number of big factions is 60 variance: 1 5x((80-66) 2+(70-66) 2+(60-66) 2x3=64Standard imitation sail difference:

Root number empty (1 5x((80-66) 2+(70-66) 2+(60-66) 2x3)=8

Dear <> will be happy to answer 1Average Score: Calculate the Empty Core Kai Formula:

Average score = (80 + 70 + 60 + 60 + 60) 5 = 66 Answer: The average score of the 5 students in the class on the statistics test is 66. Analysis:

The average score is summed according to the test scores of each student and then divided by the number of students to get the average score of 66 points in the statistical test for the five students in the class. 2.Median:

Calculation formula: Median = (60 + 60) 2 = 60 Answer: The median score of the statistics test for 5 students in this class is 60.

Analysis: The middle hidden number is to arrange all the test scores in order from small to large, and then find out the middle number, if there is an even number, then take the average of the middle two numbers, you can get the median score of the statistics test of 5 students in the class is 60 points. <>

Summary. Find the variance and standard deviation.

Now the statistical test scores of 5 students in a class are given as follows: , calculate, find the variance and standard deviation.

Here is the ** version of the answer.

Both the mode and median answers are 60

Find the median, remember to sort from smallest to largest.

What about the mean? The mean is the mean.

66 is the mean.

See the answer process of **?

Summary. Pro, summary of mathematical problem-solving methods: 1. Direct method:

According to the conditions of the multiple-choice questions, through calculation, reasoning or judgment, the final question is obtained. 2. Special value method: (special value elimination method) Some multiple-choice questions involve mathematical propositions related to the value range of letters; When solving this kind of multiple-choice question, you can consider selecting a few special values from the range of values, substituting them into the original proposition for verification, and then eliminating the wrong ones and retaining the correct ones.

3. Elimination method: return the four conclusions given by the question to the original question stem for verification one by one, and eliminate the errors until the correct answer is found. The above is mine, I hope it can help you, I wish you a happy life.
