what is of Data Accuracy?

Data accuracy is critical for businesses that rely on data-driven decision-making. Without accurate data, companies can make suboptimal decisions that cost them time and money.

Therefore, it is a critical metric that businesses should track to ensure they make the best possible decisions.

This blog post will explore data accuracy, why it’s essential, why data inaccuracy happens, and how businesses can improve their data entry accuracy. Stay tuned for more!

Data accuracy meaning

Data accuracy is the most critical aspect of data quality. It ensures that your company’s business processes are based on reliable and appropriate information, leading to better decision-making capabilities in all areas, including planning, forecasting, budgeting intelligence & more!

A company’s planning, forecasting, budgeting, business intelligence, and all such activities are based on data quality. Accuracy, consistency, timeliness, relevance, validity, and completeness are important data quality metrics.

Factors that affect data quality

If the data is irrelevant or incorrect, it can disrupt the entire working system of the business.

Data can never be 100% accurate, but it can be more or less accurate depending on how close it adheres to reality. The closer that data sticks to reality, the higher its accuracy.

In other words, data accuracy refers to the degree to which data reflects what happened in real life during a specific period.

There are two factors related to data that need to be taken care of,

  1. The data entered must be of the correct value.
  2. It must be correctly presented consistently by the expected data standards of the business and its models.

Data inaccuracy

Data accuracy illustration

Data inaccuracy is defined as “incorrect or imprecise data.” It can be caused by human error, incorrect assumptions, poorly calibrated equipment, or bad luck.

Whatever the cause, inaccurate data can lead to wrong decisions being made, which can have serious consequences. So next time you’re staring at a screen full of numbers, take a closer look – you might find an inaccuracy that needs to be corrected.

Causes of data inaccuracy

There are many causes for inaccurate data. The following three are the main causes.

1. Manual data entry

Data entry is one of the most common causes of data inaccuracy. When information is entered manually, there is always the potential for errors. Likewise, even the most careful and detail-oriented person can make mistakes when transcribing data.

That is why it’s crucial to have systems to check for errors, such as spell checkers and data validation rules. In addition, the market is flooded with tools to reduce the chances of such errors.

2. Lack of data standardization

Another common cause of data inaccuracy is the lack of data standardization. This occurs when different departments or groups within an organization use other systems or formats for storing and tracking data.

For example, one department might use all uppercase letters while another uses all lowercase letters. As a result, comparing and analyzing data from different sources can be challenging.

Another example,

EU database and other countries follow DD/MM/YY format to write the date. But the US database follows MM/DD/YY format to write the date.

Consider the date 11/12/2020. When it is converted to content, there will be no accuracy. Therefore, it isn’t easy to decide whether it is 11th December or 12th November.

3. Data decay

Finally, data accuracy can also be degraded over time due to what is known as “data decay.” This happens when information becomes outdated or irrelevant due to changes in the real-world system it represents.

For example, any links stored in a database will become obsolete and inaccurate if a website changes its URL. Data decay can also occur when data is no longer used or accessed regularly, causing it to become stale.

Over time, a firm’s existing data can become redundant and lead to data decay, such as the employees’ detail,s such as addresses or phone numbers.

Hence, the firm must ensure that it has a rigorous data team that is very dynamic and keeps a close tab on data accuracy, enhancing its overall growth and performance.

How do you check the accuracy of data?

It is crucial to check the accuracy of data. Here questions may arise on how to check the accuracy of data.

Here are two tips to check your data accuracy.

Repetitively analyze data

Analyze data from different people. For example, using an excel sheet for data entry is not easy to do a repeated data analysis because it integrates the data. Hence it is better to use high-level languages like python, SAS, etc.

Check the data with another source.

Compare the present data with another source. Sometimes it is impossible to do. However, it is the best process to check the data accuracy if possible.

How to improve data entry accuracy?

It is crucial to do accuracy verification in data entry. Here are some tips to improve data accuracy

Tips to improve data entry accuracy
  • The company needs to set an objective for data quality. Then, the organization’s top management must solve the fundamental problems troubling their data accuracy. Also, it has to set realistic goals for the data entry team.
  • Do not pressurize the data entry team. If the data entry team is under pressure, there will be a chance of data entry errors.
  • To improve the quality of data, have an accurate data source.
  • From time to time, do a data quality audit to find prevalent issues like duplicate, incomplete information, etc.
  • The company can use the Data Quality Assurance Program to ensure that the data collected from various sources are correct and relevant. This implementation will help the firm to record valuable data and keep it.

What are the skills that an employee should have for data entry?

Balance of data entry speed and data accuracy.

You know that the data entry team members play an essential role in having accurate data. Here are a few crucial skills that the members should have. You need to consider both hard skills and soft skills.

Good concentration power

She should have a high concentration while entering the data. We know that the entry person should do that work daily and continuously.

She is a person, not a machine, and has many emotions. So there will be a chance of dropping the focus, leading to inaccurate data. Hence select a person who can avoid distractions during data entry.

Trustworthy character

She must be reliable. Because many organizations lose their client because of the data stolen, when that person is unreliable, She could easily steal your organization’s critical information.

Hence while fulfilling the data entry person, check his background thoroughly and ensure he has a trustworthy character.

Experienced with needed software

The person should have the skill to operate the required software. For example, she has to work with many software programs and spreadsheet programs like excel.

The other programs he generally uses are database software, CRM software, and word processor.

So, the candidate should know all the above software and knowledge of computer hardware.

Good typing speed

It is crucial to consider the quantity of the data and quality. Hence the person should have a good typing speed with data accuracy.

You can compromise with speed but can not compromise with precision.

Good communal skill

The data entry person will not work independently. Instead, she works with the team. The data will be distributed to the team members to enter or encode within a specified time.

In the case of outsourcing, the amount of data encoded and entered will highly affect the service provider’s revenue.

So the data entry team person should regularly communicate with the other team members to ensure that the work is done.
