What is Judgment Sampling?
Judgment sampling, also known as non-statistical sampling, is a sampling technique in which the auditor selects samples based on their own expertise, assessment, and judgment rather than relying on statistical methods. This type of sampling leverages the auditor’s knowledge of the population and their understanding of the audit objectives. The main advantage of judgment sampling is its practicality in specific scenarios; however, one key limitation is that it doesn’t allow for making statistical inferences about the entire population from the sample.
Key Characteristics
- Subjective Selection: Samples are chosen based on the auditor’s personal judgment.
- Experience-Driven: Relies heavily on the experience and intuition of the auditor.
- No Statistical Basis: Does not use probabilistic techniques or allow for statistical inference.
- Targeted Approach: Can be effective in identifying key items or areas of interest quickly.
- Practical in Certain Situations: Useful when time or resources are limited or when the population is not well-suited for statistical sampling.
Examples of Judgment Sampling
Example 1: Expense Audits
An auditor reviewing travel expenses may select a sample of high-value receipts or receipts from a specific time period based on their judgment, focusing on areas that appear to have higher risks or anomalies.
Example 2: Inventory Verification
In an inventory audit, the auditor may choose items for verification based on their significance in value or frequency of movement, rather than using a random sampling method.
Example 3: Compliance Testing
When testing for compliance with specific regulatory requirements, an auditor might select samples from areas known to have had compliance issues in the past.
Frequently Asked Questions (FAQs)
Q1: What is the main disadvantage of judgment sampling?
- The primary disadvantage of judgment sampling is that it does not allow for generalizing the results from the sample to the larger population due to the lack of statistical basis.
Q2: In what scenarios is judgment sampling particularly useful?
- Judgment sampling is particularly useful in scenarios where time or resources are restricted, when the population size is small or highly variable, or when specific items of interest need to be targeted quickly.
Q3: Can judgment sampling be combined with statistical sampling methods?
- Yes, judgment sampling can be combined with statistical sampling methods in a hybrid approach to leverage the strengths of both techniques.
Q4: How does an auditor’s experience impact judgment sampling?
- The effectiveness of judgment sampling heavily depends on the auditor’s experience and expertise, as they need to make informed decisions about which samples to select.
Q5: What is the difference between judgment sampling and random sampling?
- Judgment sampling relies on the auditor’s subjective decision-making, whereas random sampling uses probabilistic methods to select samples randomly, allowing for statistical inferences.

- Audit Sampling: The process of applying audit procedures to less than 100% of items within a population to evaluate some characteristic of the population.
- Stratified Sampling: A statistical sampling method that involves dividing a population into subgroups and taking samples from each group to represent the population.
- Population: The entire set of items or data about which inferences will be made.

Accounting Basics: Judgment Sampling Fundamentals Quiz
### What is judgment sampling most reliant on?
- [ ] Random number generation
- [x] The auditor's expertise
- [ ] Specific algorithms
- [ ] Predefined statistical methods
> **Explanation:** Judgment sampling relies on the auditor's expertise and judgment to select items from a population, rather than using random or statistical methods.
### Which is a primary limitation of judgment sampling?
- [ ] It is time-consuming.
- [ ] It requires complex software.
- [x] It does not allow for statistical inferences about the larger population.
- [ ] It requires extensive training.
> **Explanation:** A key limitation of judgment sampling is that it doesn't allow for making statistical inferences about the entire population since it is based on subjective decision-making.
### In which scenario would judgment sampling likely be used?
- [x] When auditing high-value items or known risk areas quickly.
- [ ] When needing a statistically rigorous analysis of large datasets.
- [ ] Conducting a completely random audit across a large population.
- [ ] Ensuring an equal chance for all items to be selected.
> **Explanation:** Judgment sampling is effective for quickly targeting high-value items or known risk areas based on the auditor’s judgment and experience.
### Which term is best associated with judgment sampling?
- [ ] Objective selection
- [ ] Random choice
- [x] Subjective decision-making
- [ ] Statistical inference
> **Explanation:** Judgment sampling involves subjective decision-making where the auditor uses personal judgment to select samples.
### Why might an auditor use judgment sampling over statistical sampling?
- [ ] To save time and resources when a high level of statistical precision is not necessary.
- [ ] To allow for statistical inferences about the larger population.
- [ ] To meet regulatory statistical sampling requirements.
- [ ] To ensure every item in the population has an equal chance of being included.
> **Explanation:** Auditors may use judgment sampling to save time and resources when the nature of the audit does not require high-level statistical precision.
### When using judgment sampling, what factor is critical to effectiveness?
- [ ] Having a large sample size
- [x] The auditor's experience and knowledge
- [ ] The complexity of statistical models
- [ ] The randomness of the selection process
> **Explanation:** The effectiveness of judgment sampling heavily depends on the auditor’s experience and knowledge to make informed decisions about the sample selection.
### Judgment sampling is also known as:
- [ ] Probability sampling
- [x] Non-statistical sampling
- [ ] Random sampling
- [ ] Stratified sampling
> **Explanation:** Judgment sampling is also known as non-statistical sampling because it relies on the auditor’s judgment rather than statistical methods.
### Under what conditions might judgment sampling be preferred?
- [ ] When the audit requires very high statistical accuracy.
- [x] When there is limited time and the auditor’s experience can be leveraged.
- [ ] When every sample needs an equal probability of selection.
- [ ] When the population size is precisely known.
> **Explanation:** Judgment sampling is preferred when time is limited and the auditor’s experience can effectively guide the selection process.
### What is one of the practical advantages of judgment sampling?
- [x] It allows quick identification of key items or areas of interest.
- [ ] It ensures that every item has an equal chance of selection.
- [ ] It provides a statistical basis for inferences.
- [ ] It requires complex calculations and software.
> **Explanation:** Judgment sampling allows for the quick identification of key items or areas of interest due to the auditor’s directed focus.
### What is a common use-case for judgment sampling in auditing?
- [ ] Generalizing the population characteristics based on the sample.
- [x] Verifying items known to have high risk or value.
- [ ] Ensuring an entirely random distribution of sample selection.
- [ ] Performing a detailed comparison across all items in a population.
> **Explanation:** Judgment sampling is commonly used for verifying high-risk or high-value items, leveraging the auditor’s knowledge for targeted audits.
