[0002] At present, the size of ready-made garments adopts a fixed size difference. Generally, the size difference of different sizes of ready-made garments is fixed at 2 cm, 3 cm, 4 cm or 5 cm. The basic principles of statistics are not scientifically applied to the size system, resulting in the existing size difference. Unable to meet the needs of the crowd
Taking the size standard with a height difference of 5cm as an example, among females with an average height of 160cm, if the heights are 155cm, 160cm, and 165cm as the size near the average, in this case, the height is around 157.5cm and 162.5cm It is difficult to find a suitable size for the crowd; at the same time, according to the principle of normal distribution, the probability of these two heights appearing in the crowd is very high; therefore, the existing grading system makes it impossible for many people to find the corresponding size

[0011] In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose of the invention, the specific implementation methods, features and effects according to the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Taking the height of senior three girls in a certain school as an example, the method of determining clothing size based on normal distribution. The following data units are in centimeters. Proceed as follows:

[0013] (1) Collect the height data of a senior high school girl, and draw the normal distribution curve of the height data;

[0014] (2) Calculate mean value μ=160.4 and standard deviation δ=5.4;

[0015] (3) Taking the mean data as the reference data, according to the normal distribution law, there are the following solutions:

[0016] The target population can be divided into 5 intervals with the same number, and brought into the probabi...

Abstract

The invention relates to a garment size determination method based on normal distribution, and belongs to the field of garment engineering. At present, a fixed size difference is adopted for the sizeof a ready-made garment, and the basic principle of statistics is not scientifically applied to a size system, so that the existing size cannot meet the requirements of people. According to the method, the population is divided according to the population density ratio occupied by different body sizes by referring to the normal distribution principle, so that the number of people in a certain interval is the same or similar, and the purpose of scientific code release is achieved.

Description

technical field [0001] The invention relates to a method for determining clothing size based on normal distribution. The clothing size difference is adapted to the population density of the body size of the target group. Background technique [0002] At present, the size of ready-made garments adopts a fixed size difference. Generally, the size difference of different sizes of ready-made garments is fixed at 2 cm, 3 cm, 4 cm or 5 cm. The basic principles of statistics are not scientifically applied to the size system, resulting in the existing size difference. Unable to meet the needs of the crowd. Taking the size standard with a height difference of 5cm as an example, among females with an average height of 160cm, if the heights are 155cm, 160cm, and 165cm as the size near the average, in this case, the height is around 157.5cm and 162.5cm It is difficult to find a suitable size for the crowd; at the same time, according to the principle of normal distribution, the probabi...
