Abstract

The present invention proposes a sampling method and a sampling device, wherein the sampling method includes: according to the specified sub-layer attributes, respectively stratify the experimental sample set and the control sample set to obtain each sub-layer of the experimental sample set The first sampling amount of and the second sampling amount of each sub-layer of the control sample set; when the second sampling amount of each sub-layer is not greater than the first sampling amount, or when the first sampling amount is not greater than the expected stratification amount of the control, Select the first target proportional relationship that meets the first specified condition from the proportional relationship between the first sampling amount and the second sampling amount of each sub-layer; according to the first target proportional relationship and the first sampling amount of each sub-layer, each sub-layer is obtained The third sampling amount of the stratum; the experimental sample set and the control sample set are sampled according to the third sampling amount. Through the technical solution of the invention, more representative samples can be drawn, thereby improving the effectiveness of the sampling inspection results.

Description

【Technical field】 [0001] The invention relates to the technical field of data processing, in particular to a sampling method and a sampling device. 【Background technique】 [0002] Currently, there are two commonly used methods when sampling two user groups: [0003] First, given the sample sizes that need to be drawn from each of the two user groups, the two user groups are sampled symmetrically by random sampling. [0004] Second, a user group with a digital account system can be randomly sampled according to certain digits of the digital account. For example, the first three digits of the digital account are 839, the middle three digits are random numbers, and the last two digits are 07. As a sample, 1000 random users with the middle three digits of the digital account numbers ranging from 000 to 999 will be generated. [0005] However, in the actual sampling process, the smaller the difference in dimensions other than the dimension to be investigated, the more accurate ...
