It is based on the concept that each monetary unit e. In MUS, the population is divided into individual monetary units.

If you want a funnier definition of MUS, please read here wink. Monetary Unit Sampling is a sampling technique specifically designed for use in audits.

Because of that, it carries the advantages and disadvantages of statistical sampling in general. Plus, it addresses issues specific to the audit realm, e. By its nature, Monetary Unit Sampling sees each dollar as an individual sample unit.

Consequently, each item or transaction with a larger number has a bigger chance of being selected as a sample. Stratification, while useful in certain contexts, adds a layer of complexity to the sampling process.

It involves dividing the population into distinct layers or strata based on specific characteristics and sampling from each stratum. MUS simplifies the process by treating each monetary unit as a potential sample point, reducing the need for the preliminary step.

All steps in MUS, such as picking the sample size, selecting items as samples, and inferring the result to populations, have their procedures.

This also helps ensure a methodical approach to sampling work. The sample size in MUS is calculated based on statistical principles, allowing auditors to justify the sample size selected. As you may see here , several methods exist to calculate and justify the sample size in the Monetary Unit Sampling.

If misstatements exist in the sample, the auditor can easily examine whether the overall misstatements are below the predefined Tolerable Misstatement or surpass the safe bar.

The feature provides an objective basis for audit conclusions. Another benefit is enhanced credibility with stakeholders such as management, audit committees, and external parties. With the ability to present quantified estimates of misstatement, the auditor gains the credibility of the audit findings.

When using statistical tools, you must consider several population characteristics and fulfill statistical assumptions e. Another benefit of MUS is that it does not assume that the population follows a normal distribution.

This is particularly advantageous because financial data often do not conform to normal distribution. Just like other things in the world, Monetary Unit Sampling also has several disadvantages.

You need to know the downside of the method to avoid using it wrongly, which can backfire on your audit conclusion. Below is the list of the disadvantages of MUS. Implementing MUS requires a good understanding of statistical principles and audit software.

Setting up MUS, selecting a sample, and analyzing the results can be time-consuming, especially for auditors not well-versed in statistical sampling techniques.

On the other hand, giving additional training for audit staff can be time-consuming and might involve additional costs for the firm. They are shown here for illustrative purposes. Note that in this example, the favorable and unfavorable adjustments net to zero.

So, the taxpayer filed the correct amount even though projects were a little under- or overstated. Thus, the taxpayer ends up in an unfavorable position.

There is no reduction of the adjustment due to inaccuracies from a smaller size. Typically, the sample size is more than four projects; the small sample size here is for illustrative purposes. With a small or large sample, however, the point is the same: The taxpayer could end up with an inaccurate unfavorable adjustment due to a biased sampling method, even when the taxpayer chooses half of the sample selections.

Example 3. More on small random samples labeled as judgmental samples: As discussed above, when specified criteria for a statistical sample yield a large sample size, the IRS may approach the taxpayer to agree to use an extrapolated adjustment from a smaller judgmental sample.

However, the judgmental sample is randomly selected just like a statistical sample. In actuality, if they consent, the taxpayer agrees to an inaccurate sample and allows the IRS to ignore the inaccuracy. The margin of error ME is the plus or minus amount reported around an estimate.

It describes how much an estimate may vary in relationship to itself. The IRS measures accuracy in terms of relative precision. Note that zero is inside the confidence interval — which means there is no statistically supported evidence that there even should be any adjustment at all.

Yes, the IRS would owe the taxpayer in this hypothetical scenario with these facts. By agreeing to a judgmental sample, this taxpayer pays an unfavorable adjustment when there should not be any and gives up on the reduction of the adjustment due to imprecision resulting from the small sample size.

In summary, it is advisable in general to avoid judgmental samples when quantifying an adjustment to a figure on a tax return.

They can be biased and result in wild estimates, and taxpayers lose out on IRS adjustment reductions due to poor precision. However, they can be appealing to a taxpayer — especially with the smaller size of the audit. Know what is being given up by agreeing to a judgmental sample approach, though.

A statistician can quantify that for your company under hypothetical scenarios. By contrast, the accuracy of statistical samples can be mathematically determined, which is why they are more defensible in court.

Therefore, statistical samples should be used by taxpayers when they conduct samples to estimate values for tax returns. Furthermore, taxpayers would be wise to advocate to be audited under a statistical rather than a judgmental sample plan. This reduces the risk of undue adjustments due to a poor statistical plan.

In the case of IRS audits, this also maintains the adjustment reduction from inaccuracies should the IRS choose to use a smaller sample size.

A possible sampling unit for record sampling can be the date of payment of the receipt. When a sampling unit e. A sampling unit for monetary unit sampling is different than a sampling unit for record sampling in that it is an individual monetary unit within an item or transaction, like an individual dollar.

This section discusses the four sampling methods implemented in jfa. The next section discusses which sampling methods are available in jfa. To illustrate the outcomes for different sampling methods, we will use the BuildIt data set that can be loaded using the code below.

Fixed interval sampling is a method designed for yielding representative samples from monetary populations.

The algorithm determines a uniform interval on the optionally ranked sampling units. Next, a starting point is handpicked or randomly selected in the first interval and a sampling unit is selected throughout the population at each of the uniform intervals from the starting point. For example, if the interval has a width of 10 sampling units and sampling unit number 5 is chosen as the starting point, the sampling units 5, 15, 25, etc.

are selected to be included in the sample. If the space between the selected sampling units is equal, the selection probability for each sampling unit is theoretically defined as:.

However, in practice the selection is deterministic and completely depends on the chosen starting points using start. The fixed interval method yields a sample that allows every sampling unit in the population an equal chance of being selected.

Note that, if the population is arranged randomly with respect to its deviation pattern, fixed interval sampling is equivalent to random selection. Advantage s : The advantage of the fixed interval sampling method is that it is often simple to understand and fast to perform.

Another advantage is that, in monetary unit sampling, all items that are greater than the calculated interval will be included in the sample. In record sampling, since units can be ranked on the basis of value, there is also a guarantee that some large items will be in the sample.

Disadvantage s : A pattern in the population can coincide with the selected interval, rendering the sample less representative. What is sometimes seen as an added complication for this method is that the sample is hard to extend after drawing the initial sample.

This is due to the chance of selecting the same sampling unit. However, by removing the already selected sampling units from the population and redrawing the intervals this problem can be efficiently solved. As an example, the code below shows how to apply the fixed interval sampling method in a record sampling and a monetary unit sampling setting.

Note that, by default, the first sampling unit from each interval is selected. Like in the fixed interval sampling method, the selection probability for each sampling unit is defined as:. It is argued that the cell sampling algorithm offers a solution to the pattern problem in fixed interval sampling.

Disadvantage s : A disadvantage of this sampling method is that not all items in the population with a monetary value larger than the interval have a selection probability of one. Besides, population items can be in two adjacent cells, thereby creating the possibility that an items is included in the sample twice.

As an example, the code below shows how to apply the cell sampling method in a record sampling and a monetary unit sampling setting. It is important to set a seed to make the results reproducible. Random sampling is the most simple and straight-forward selection method The random sampling method provides a method that allows every sampling unit in the population an equal chance of being selected, meaning that every combination of sampling units has the same probability of being selected as every other combination of the same number of sampling units.

Therefore, the selection probability for each sampling unit is defined as:. To clarify this procedure, Figure 3 provides an illustration of the random sampling method. Advantage s : The random sampling method yields an optimal random selection, with the additional advantage that the sample can be easily extended by applying the same method again.

Disadvantages: Because the selection probabilities are equal for all sampling units there is no guarantee that items with a large monetary value in the population will be included in the sample.

As an example, the code below shows how to apply the random sampling with our without replacement using replace method in a record sampling and a monetary unit sampling setting.

It is important to set a seed to make results reproducible. Next, the sieve ratio:. With traditional product sampling, your insights are limited to what you see right then and there and depend on the accuracy of the person that records them.

Therefore this is not a suitable method for products that take a day or a week to try out and review, like shampoos or skincare products. The digital age of technology has made it convenient for both businesses and consumers to connect with each other.

Digital product sampling is the natural evolution of the traditional product sampling method in the modern world. With this technique, you are targeting specific audiences and not a vast number of random by-passers.

Despite the fact that the traditional product sampling technique offers face-to-face interactions, the digital product sampling technique offers your users some form of anonymity that enables them to be honest.

Moreover, you can always follow up on your potential consumers via this method, but with the traditional product sampling method, you will lose touch with them. Your campaign result is not dependent on the note-taking skills of your employees.

There is a data-gathering method involved that helps you keep track of your results and analyze them in different ways. This higher cost is usually compensated by creating a loyal consumer base and eventually a much higher return on investment ROI rate.

Read more: Digital Product Sampling vs. Traditional Product Sampling. We highly recommend that you opt for the second option and take the digital product sampling route.

It may be a longer one, but you will get where you want to be, satisfied. If you know what group of people you want to target, get to know them on a deeper level, and if you want to find the right target market for your product, study the market and your competitors' consumer base.

This will help generate reviews and will give consumers a chance to familiarize themselves with your product. In addition, pick the right time for your product launch.

For example, try launching your school supply product a few weeks before the new semester starts. You can send post-purchase emails; send out questionnaires.

However, there are applications and companies that can manage the whole process of product sampling for you and even handle post-purchase updates, which is a challenging and dubious task. Keep your ear to the ground and read reviews.

Reply as much as you can and resolve consumer concerns to the best of your ability. Product sampling is a process, meaning there is no finish line. You can always tweak and repeat this procedure to maintain the product-market-fit status.

If you are going to plan a product sampling campaign and want it to succeed, you have to answer the following questions honestly:.

Answering these questions specifically helps you to plan your product sampling marketing road map. Yet, we know that finding the exact answer to some of these questions may be challenging, and that is why Peekage offers a free consultation session to its customers before starting any product sampling procedure.

If you are going to manage a product sampling campaign and want it to succeed, you have to be extremely detail-oriented and great at follow-ups.

Here are some obstacles you may encounter while managing a product sampling campaign:. sometimes, each team member has a different goal in mind for a campaign, sometimes you may set goals that are not in alignment with your overall growth strategy, and other times you may set goals that are not measurable or attainable.

You may have difficulties knowing who will be a good match for your product and where they live. Basically, you need access to a live and updated database. You have to know how many samples you will need, how much they will cost, where you want to store them, and how you want to deliver them.

Being on top of all product-related tasks is a handful. Managing finances in a product sampling is more than just estimating a number it will cost. You have to adhere to your spending plan every step of the way. Depending on your delivery method, you need to consider packaging, storing, and shipment, which all may alter the final cost estimation and screw up your timetable.

Again, depending on your chosen method, you have to be prepared to answer your customers about any number of things, including delivery mix-ups, faulty packages, complaints, comments, etc. You must have a unified method of data gathering within your company.

All your product sampling team members have to have the same accuracy in data collection and recording. After gathering user feedback, you need to analyze it into useful information that is meaningful for your product owner and design team.
