This Excel is composed of a few tabs:

1. How to Use

This is the first tab and its purpose is to give you guidance on how to use it and what are the purposes and goals of this tool.

2. Data

This tab is designed to support your calculation process by allowing you to enter the data from your study. Simply copy your participants' answers into the table. The calculator is equipped to handle missing data for up to three values per participant, so there's no need to clean or prepare your data beforehand. If you also included demographic questions in your study, the calculator can process this data as well. Just copy the demographic information into the table and edit the header as needed. Note that the calculator is capable of processing data for up to 1000 participants. If your sample size exceeds this limit, the formulas may not be able to handle the data accurately.

3. SUS Calculation

This tab is where all the calculations for your SUS study are done automatically. You don't need to do anything here except view the results. In this spreadsheet, you can compare your SUS score to other market products such as B2B or B2C solutions, or specific websites. You can also see the SUS score for each individual participant and how their answers deviate from the mean. Additionally, you can inspect the data for any outliers. If you find any, simply go back to the Data spreadsheet and delete those participants.

4. Results Dashboard

Welcome to the magic dashboard! This amazing tool has been prepared for you to see your SUS score, its corresponding grade, and what it means for your product or system. You can also compare your score to the market average and evaluate your solution's performance in several dimensions, such as ease of use, consistency, and complexity. The dashboard also displays the distribution of your scores, allowing you to evaluate each question's performance and make informed decisions based on the results.

5. Demographics Dashboard

This is a simple dashboard where you can visually analyze the demographic statistics of your questionnaire. I have built a dynamic map where you can filter your participants by region and country.

6. SUS Correlations

In this tab of the spreadsheet, you can evaluate if some individual factors may or may not influence your SUS score. For example, you can see how age groups tend to evaluate the usability and learnability of your solution. So, use this tab to:

- Identifying areas for improvement: By correlating SUS scores with specific factors you can identify areas where the product or service may need improvement. For example, if you notice that SUS scores are lower among users who are less experienced with technology, you may need to provide more user-friendly interfaces or better training resources.

- Understanding user behavior: Correlating SUS scores with other factors can also help you understand how users interact with your product or service. For example, if you notice that SUS scores are very different from country to country, you may do further user research to understand if cultural aspects or logistics may affect how your users perceive the quality of your product or service.

- Validating design decisions: Correlating SUS scores with design decisions can help you determine whether your design choices are effective. For example, if you notice that SUS scores are lower among older users you may have to adjust the experience to onboard this type of user group.

7. Answers Distribution

In this tab of the spreadsheet, you can consult the distribution of results by question.
