Uncertainty figures – Confidence in the way the police conduct their work, percentage (%)

This is an uncertainty number, for more information see Unsafe data on kolada.se. “Confidence in the way the police conduct their work, percentage (%)” is an excise estimate from a sample survey. This means that the estimate is not necessarily representative of the population as a whole. However, with the point estimate ± the uncertainty number, one can most likely say that the true mean is within the range. Brå uses asymmetric confidence intervals, in Kolada the uncertainty number is given as the maximum distance between the confidence interval and the point estimate. This means that the point estimate ± uncertainty may differ in one direction to the confidence interval from the NTU. For example, 2019-2020 is merged and published for the last year, such as the year 2020 in Kolada, the results for 2021 and 2022 are merged and the joint result will be published in the year 2022 in Kolada.本数值为不确定度数值（uncertainty number），更多信息请参阅kolada.se网站上的「不安全数据」板块。「警方执法工作认可度（百分比，%）」为基于抽样调查得出的预估估算值。这意味着该估算值未必能完全代表目标总体。不过，借助点估计值（point estimate）与不确定度数值的加减区间，大概率可以认为总体真实均值处于该区间范围内。Brå采用非对称置信区间（confidence interval），而在Kolada平台中，不确定度数值被定义为置信区间与点估计值之间的最大距离。这意味着点估计值±不确定度的区间与NTU给出的置信区间在方向上可能存在差异。例如，2019-2020年的数据会合并后以最后一年的名义发布，如在Kolada平台中以2020年的名义发布；2021年与2022年的统计结果将被合并，并于2022年在Kolada平台发布联合统计结果。
