Both groups are categorical variables and should be correlated with kendall.
It is a low correlation, which is the size of the nucleus of the correlation coefficient of the analysis.

If the two sets of data are similar, they may be highly or uncorrelated, depending on the actual situation of the two sets of data.
Typically, correlation refers to the strength of the linear relationship between two sets of data, which can be measured by correlation coefficients. When there is a linear relationship between two sets of data, their correlation will be high, and the correlation coefficient will be close to 1 or -1. If there is no obvious linear relationship between the two sets of data, then their correlation will be low, and the correlation coefficient will be close to 0.
However, if two sets of data are similar, but the relationship between them is not linear, then their correlation may be low, even if the difference between them is small.
Therefore, it is necessary to judge their relevance according to the specific data situation. If the data of the two hail groups are similar, but the relationship between them is linear, then their correlation will be higher. If two sets of data are similar, but the relationship between them is not linear, then their correlation may be low.

If two sets of data are similar, the correlation between their siblings may be high or low, depending on the relationship between them. Correlation refers to the degree of relationship between two or more variables, which can be measured by correlation coefficients. If there is a ** relationship between two sets of data, their correlation may be high, and the correlation coefficient is close to 1.
However, if the relationship between them is nonlinear, the correlation may be low, with a correlation coefficient close to 0. Also, even if there is some correlation between two sets of data, the causal relationship between them cannot be determined because correlation does not imply causation. Therefore, when analyzing data, several factors need to be considered in combination to determine the relationship between them.

The proximity of the two sets of data does not mean that there is a high correlation between them. Liquid correlation is a measure of the linear relationship between two sets of variables, with values between -1 and +1. If the two sets of variables exhibit a perfect positive correlation, the correlation coefficient is +1;-1 if there is a perfect negative correlation; If there is no linear relationship between the two sets of variables, the correlation coefficient is 0.
Therefore, the similarity of the two sets of data does not necessarily indicate that the correlation coefficient is high or low. For example, if we compare two sets of very similar, but completely uncorrelated, random data, their correlation coefficient will be 0 and vice versa. Therefore, in order to determine the correlation between the two sets of data, it is necessary to calculate the correlation coefficient by taking the cheat.

If two sets of data are close in age, then the correlation between them will be high. Correlation is a linear relationship between two variables, and the correlation between two variables is higher when the data between them are similar. This means that when one variable changes, the other variable also changes, and the magnitude of the change is greater.
Therefore, if two sets of data collide with each other, then the correlation between them will be high.
-
If the two sets of data are similar, i.e., their value distributions or trends are similar, then their correlation is usually higher. Because correlation is a measure of the relationship between two variables, if the values between two variables are more similar, the closer the relationship between them will be, and the higher the correlation. However, it should be noted that there is no equivalence between proximity and high correlation, and the similarity of two sets of data does not always equate to the high correlation between them.
-
If the two sets of data are close to each other, the correlation between them is usually higher. Correlation refers to the degree of relationship between two variables, and if there is a correlation between two pre-friend variables, their trends are usually similar. Therefore, if two sets of data are similar, the correlation between them is usually higher.

To determine the correlation between two sets of data, it is necessary to use correlation coefficients or other statistical methods for analysis, and the correlation between them cannot be determined based on the similarity of the data alone.
The similarity of two sets of data does not necessarily mean that they have a high correlation, because correlation and similarity are two different concepts. Correlation is used to describe the strength and direction of the relationship between two variables, while similarity simply indicates the degree of similarity between the two groups of data in some way. Therefore, the similarity of two sets of data does not mean that there is no high correlation between them, nor does it mean that there is no absolute correlation between them.
For example, let's say we have two sets of data, one is the temperature per day and the ice cream sales. The two sets of data may be similar in some ways, such as an increase in ice cream sales in the summer when temperatures rise. However, in other ways, they may not be related, such as ice cream sales drop on cold days, but temperatures don't.

1. Generally speaking, after taking the absolute value, there is no correlation, weak, weak correlation, medium correlation, and strong correlation. However, it is often necessary to do a significant difference test, which is a T-test, to test whether the two sets of data are significantly correlated, which is automatically calculated in SPSS. Second, the larger the sample book, the smaller the correlation coefficient that needs to be related to significance.
So this is related to the sample size, if the sample is large, say more than 300, often the correlation coefficient is relatively low, for example, because the sample size increases the difference of Shouchang, but the significance test considers this to be an extremely significant correlation. 3. The strength of the judgment is mainly based on the significance, rather than the correlation coefficient itself. However, both statistics need to be reported at the same time when writing **.
