Numbers are tripartite (e.g. 2,431), but the year, page number, unit designation, instrument model, and standard number are not tripartite. The mean should be accompanied by standard deviation, and uniformly reserved to 1 decimal place; When the data distribution is obviously skewed, the median quartile spacing method [M (P25, P75)] is used to show the degree of dispersion of the data. Statistical values such as t-values, x2 values, and p-values are kept to 3 decimal places. When the area or volume is multiplied by length, the numerical units cannot be omitted, such as 20cm×25cm×28cm shall not be written as 20×25×28cm3.

3.6 Statistical Methods

Measurement data were expressed as mean ± standard deviation (x±s), and independent sample t test was used for comparison between the two groups. Single factor analysis of variance was used for comparison among multiple groups, and LDS method was used for pair-to-group comparison. When the distribution of data is obviously skewed, and the characteristics of data skew need to be emphasized, the median quartile interval method [M (P25, P75)] should be used to express, and non-parametric statistical method should be adopted. The counting data of rank variables and dichotomous variables were represented by the number of cases. Mann-Whitney U test or Chi-square test were used to compare the two groups. Other special statistical test methods are described according to actual use. State the inspection level.
