What are the methods of data processing and statistical analysis in scientific research papers?
There are many methods of data processing and statistical analysis in scientific research papers. Here are some common methods:

Descriptive statistics: describe the distribution and basic characteristics of data by calculating the average, median, standard deviation and variance of data.

-Inference statistics: infer the properties of the whole data from the sample data, such as hypothesis test, confidence interval, etc.

-Regression analysis: used to study the relationship between two or more variables, such as linear regression and multiple regression.

-Analysis of variance: used to compare the average of three or more samples.

-Correlation analysis: used to study the relationship between two variables, such as Pearson correlation coefficient and Spearman rank correlation coefficient.
