Shift s-var →→ 1 = calculate a
Shift s-var →→ 2 = calculate B
Substituting y = BX + A

The sum of squares of each deviation of a group of data is related to the data itself, but has nothing to do with the capacity of the data

It should be related to the sample size. If it is only the sum of squares, the larger the size is, the larger the sum of squares may be. Right? Get the answer

How to use SPSS12.0 software for chi square test to judge whether the difference between the two groups is statistically significant?
Number of cases in group junior high school and below, junior college and above
The experimental group was 52 22 23 7
Control group 50 18 24 8

After analyzing -- descriptive -- crosstabs click in, row is the experimental processing (Group), column is the number of people, statistical check chi square, OK data entry effect picture is variable1 variable2 variable31 1221 2231 372 1182 2242 2338, and then press dat

What is the meaning of variation in statistics and its statistical significance?

In a population, there are differences in the performance of quality marks or quantity marks of each unit. For example, gender marks are male and female. This difference is called variation. Variation can be divided into attribute variation and numerical variation. Attribute variation is only limited to quality marks, while numerical variation is limited to quantity marks and statistical indicators. Variation is the precondition of statistics. Only when there is variation can there be statistics, Without variation, there is no need for statistics

Difference refers to the sample or the whole! P > 0.05 if it refers to the sample difference is not statistically significant, then why P

The principle of statistical test is based on the principle of "small probability events will not happen", so we often see that the significance level is 0.01, 0.05. And the p value is the probability of assuming that the original hypothesis is true and producing a worse sample than the current sample

What is the meaning of mean difference statistically significant and comparative difference statistically significant?
What do you mean the mean difference is statistically significant? Does it mean the mean difference between the two groups is statistically significant? What does it mean to compare the difference? Don't be too long. Try to be concise and easy to understand. Thank you~~
Let me add another explanation. For example, there are three groups of data, one is 123 groups, and the mean value of these three groups of data is statistically significant. Then, there is a statistical difference between the data of group 1 and three groups. What is the difference between this comparative difference and the mean value of the three groups mentioned before?

I don't know what your question is, but guess it is the following meaning. For example, you have two groups of students' test scores. Now check whether the average scores of these two groups are the same. Of course, it is almost impossible for the observed samples that the two average values are exactly the same, so we use the concept of distribution to do this

Rank sum test is fine

What is the meaning of "sum of squares of deviation" in statistics,

Let the sample data be x1, X2 , xn, the average is x,
Then (x1-x) & sup2; + (x2-x) & sup2; + +(xn-x) & sup2; is the sum of squares of mean deviations,
The smaller the sum of squares of deviation, the more stable the sample data is

My daughter's math problem: A. A is equal to 2a, so what does a stand for? I also want to know what. Stands for in this problem? Does it mean multiplication?
What does a stand for?

Seventh grade?
a. A = 2A means that the quadratic power of a [or a times a] equals 2A
