So that the evaluation process and audit results are not distributed outside the company. However, these audits are potentially affected by conflicts of interest.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/audithink.com\/en\/article\/what-is-external-audit\/\" data-type=\"post\" data-id=\"2889\">External Audit<\/a><\/strong>, it is carried out by a party that can give an opinion in a fair and impartial way, making it possible to avoid fraud.<\/li>\n\n\n\n<li><strong>Government Audit<\/strong>, implemented by government tools to carefully evaluate government financial data, such as on corporate taxpayer reports listed on the stock market.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Read Also:<\/strong><a href=\"https:\/\/audithink.com\/en\/article\/difference-audit-internal-and-external\/\"><strong> <\/strong>7 Differences between Internal and External Audit, Let's Know!<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Audit Sampling Method&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In taking audit sampling to form conclusions and provide opinions in accordance with the objectives set without evaluating the entire population, there are two methods that can be done. Among them are:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. <em>Statistical<\/em> Audit Sampling&nbsp;<\/h3>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"738\" src=\"https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/statistic-freepik-1024x738.webp\" alt=\"Metode statistical audit sampling\" class=\"wp-image-3609\" title=\"\" srcset=\"https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/statistic-freepik-1024x738.webp 1024w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/statistic-freepik-300x216.webp 300w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/statistic-freepik-768x554.webp 768w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/statistic-freepik-1536x1107.webp 1536w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/statistic-freepik-2048x1476.webp 2048w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/statistic-freepik-18x12.webp 18w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Statistical Audit Sampling (Sumber: Freepik)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This method carries out statistical or random sampling to be tested. This is generally done on data with a high number of populations, complete and accurate as a whole, homogeneous items, and allows for random selection.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this case, each 1:100 item has an equivalent probability of being retrieved and verified for accuracy, which however will still make it easier for auditors because there is no need to check the entire data.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. <em>Non-Statistical<\/em> Audit Sampling&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This method is the opposite, where the sampling is not done randomly, but relies on the ability and judgment of the auditor.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to the auditor's judgment, the results of the audit also can not be used to represent the entire population. This is because the data tested by this method must be unequal, impossible to select at random, or there is no complete and accurate list of all items.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not like on <em>statistical audit<\/em> which 10 items can give conclusions from 100 data, methods <em>non-statistical<\/em> audit sampling is selected by the auditor based on provisions, such as transaction values totaling more than 100,000, specifications of items related to a company, and others.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Purpose Of Audit Sampling&nbsp;<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Provide sufficient evidence for the auditor to derive conclusions from the entire item by testing a small portion of the population<\/li>\n\n\n\n<li>Improve efficiency and save audit costs and resources used&nbsp;<\/li>\n\n\n\n<li>Provide a basis for concluding opinions with a certain degree of stability in the population<\/li>\n\n\n\n<li>Check the accuracy and completeness of the data and identify errors or discrepancies that may occur<\/li>\n\n\n\n<li>Ensure auditors conduct audits in accordance with their standards<\/li>\n\n\n\n<li>Become a tool to investigate all audit-related information<\/li>\n<\/ul>\n\n\n\t\t<div data-elementor-type=\"section\" data-elementor-id=\"5427\" class=\"elementor elementor-5427\" data-elementor-post-type=\"elementor_library\">\r\n\t\t\t<div class=\"elementor-element elementor-element-c693698 e-flex e-con-boxed e-con e-parent\" data-id=\"c693698\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-f131bf4 cta-banner-article elementor-widget elementor-widget-image\" data-id=\"f131bf4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/audithink.com\/en\/demo\/?utm_source=blog&#038;utm_medium=cta-banner&#038;utm_campaign=request-demo-cta-banner&#038;utm_content=request-demo-aplikasi-audit-banner\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"2400\" height=\"800\" src=\"https:\/\/audithink.com\/wp-content\/uploads\/2026\/07\/audithink-banner-v3-photo.webp\" class=\"attachment-full size-full wp-image-5428\" alt=\"cta banner campaign\" srcset=\"https:\/\/audithink.com\/wp-content\/uploads\/2026\/07\/audithink-banner-v3-photo.webp 2400w, https:\/\/audithink.com\/wp-content\/uploads\/2026\/07\/audithink-banner-v3-photo-300x100.webp 300w, https:\/\/audithink.com\/wp-content\/uploads\/2026\/07\/audithink-banner-v3-photo-1024x341.webp 1024w, https:\/\/audithink.com\/wp-content\/uploads\/2026\/07\/audithink-banner-v3-photo-768x256.webp 768w, https:\/\/audithink.com\/wp-content\/uploads\/2026\/07\/audithink-banner-v3-photo-1536x512.webp 1536w, https:\/\/audithink.com\/wp-content\/uploads\/2026\/07\/audithink-banner-v3-photo-2048x683.webp 2048w, https:\/\/audithink.com\/wp-content\/uploads\/2026\/07\/audithink-banner-v3-photo-18x6.webp 18w\" sizes=\"(max-width: 2400px) 100vw, 2400px\" title=\"\">\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\r\n\t\t\n\n\n\n<h2 class=\"wp-block-heading\">Stages Of A Sample Audit&nbsp;<\/h2>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"745\" src=\"https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/audit-freepik-1024x745.webp\" alt=\"Stages of audit sampling\" class=\"wp-image-3610\" title=\"\" srcset=\"https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/audit-freepik-1024x745.webp 1024w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/audit-freepik-300x218.webp 300w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/audit-freepik-768x559.webp 768w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/audit-freepik-1536x1118.webp 1536w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/audit-freepik-2048x1490.webp 2048w, https:\/\/audithink.com\/wp-content\/uploads\/2024\/12\/audit-freepik-16x12.webp 16w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Illustration Of Audit Sampling (Source: Freepik)<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">1. Setting Sampling Goals&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Determining the purpose of sampling means setting the purpose of the audit itself. An auditor needs to ensure that the data identified is in accordance with audit standards, for example, anyone involved in <a href=\"https:\/\/audithink.com\/en\/article\/audit-process\/\" data-type=\"post\" data-id=\"3511\">the audit process<\/a>.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Identifying The Population&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Before establishing a sample, the auditor needs to review its population because the audit process will only take a portion of the overall data.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows the auditor to consider important aspects within the population, such as the scope and area to be audited so that the auditor can determine the extent of sampling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Choosing A Sampling Method&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">At this stage, the auditor can decide which method to use to collect samples. Will be based on the auditor's consideration with <em>non-statistical<\/em>, or by a random method with <em>statistical method<\/em>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the auditor uses a statistical sample, it is necessary to ensure that the characteristics of the entire population are accurate and complete, allow for randomization, and are homogeneous.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That's because sampling with statistical methods will only bring up two possibilities, true or false. It is therefore necessary to identify the population before choosing a method.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Likewise, when the auditor decides to take a sample based on his assessment of all the data, it is necessary to consider the experience in the scope of the audit, the complex requirements to achieve the objectives of the audit, weigh the complexity of the interaction and management system of the institution, assess changes in technology, and much more.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Determining The Size Of The Sample&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Auditors must be skilled in determining the amount of samples to be reviewed based on the time given.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even with limited time, auditors are expected to be able to create a realistic sample size so that the audit process can run optimally.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Conduct A Sample Audit&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Auditors with all strategies that have been prepared to ensure the credibility of the audit process continues to run as planned by remaining flexible to changes that remain measurable in the audit success benchmark.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Case Study Examples<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For example, an auditor is doing calculations on an organization that has 50,000 transactions in one year. In this case the auditor sets 500 samples for the entire population.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>On random data retrieval<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If in 500 samples of 50,000 transactions 5 transaction errors are identified, then the picture of the discrepancy is 1% (5\/500 of 100%) which is then projected on the entire number of 50,000 transactions. So that from 1% of 50,000 shows that out of 50,000 transactions, there are likely to be 500 transactions that do not match.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>On non-statistical data retrieval&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If 500 samples are taken out of 50,000 it is based on transactions related to one particular company. After identification, the auditor found 2 transactions that did not match. After testing each transaction with a sample and testing for discrepancies, the auditor with his judgment and capabilities can determine the intended discrepancies and decide to take appropriate measures in accordance with his needs.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ About <em>Audit Sampling<\/em><\/h2>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>What is <em>audit sampling<\/em>?<\/strong><\/summary>\n<p class=\"wp-block-paragraph\"><em>Audit sampling<\/em> is a method of taking and investigating a small sample from the whole population for testing, then using it as the benchmark for conclusions about the entire population \u2014 so auditors do not need to examine every data item.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>What is the purpose of a <em>audit sampling<\/em>?<\/strong><\/summary>\n<p class=\"wp-block-paragraph\">Providing sufficient evidence to draw conclusions about all items, improving efficiency while saving audit costs and resources, providing a basis for concluding an opinion on the population, checking data accuracy and completeness, and ensuring the audit is conducted according to its standards.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>What are the methods of <em>audit sampling<\/em>?<\/strong><\/summary>\n<p class=\"wp-block-paragraph\">Two methods: <em>statistical audit sampling<\/em> which draws samples randomly, and <em>non-statistical audit sampling<\/em> whose sample selection relies on the auditor's skill and judgment.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>When is the statistical method suitable?<\/strong><\/summary>\n<p class=\"wp-block-paragraph\">When the population is large, the data is complete and accurate overall, the items are homogeneous, and random selection is possible.
