Power BI Masterclass - Learning DAX: Customer Classification with Custom Label Calculation

The video tutorial explains how to classify customers based on their transaction history over the last 30 days. It involves creating a helper table with classification labels and thresholds, implementing a DAX formula to assign labels, and using filter functions to ensure accurate context modification. The tutorial also covers testing and refining the formula to improve classification logic.

What is the purpose of classifying customers based on transaction frequency?

• To determine the most profitable products

• To calculate total sales revenue

• To identify customer loyalty levels

• To categorize customers into risk levels

Which of the following is NOT a label used for customer classification in the video?

• Average

• Premium

• Risky

• Top

What is the significance of setting a high maximum threshold for the 'Top' customer category?

• To accommodate future data changes

• To simplify the classification process

• To exclude outliers from the data

• To ensure all customers are classified

Why is there no relationship between the customer classification table and the model?

• To enhance data security

• To simplify the data model

• To prevent data duplication

• Because it is not needed for classification

What function is used to ensure that only one label is returned for each customer?

• SUM

• CALCULATE

• SELECTEDVALUE

• FILTER

How does the FILTER function contribute to the customer classification process?

• It removes duplicate entries

• It calculates the total transactions

• It modifies the context for evaluation

• It sorts the data in ascending order

What is the purpose of using the ALL function in the classification logic?

• To calculate the average transactions

• To sort the data alphabetically

• To remove all external filters

• To apply filters to the data

What does the 'is in scope' condition check for in the enhanced classification logic?

• If a customer has made a purchase

• If a specific column is present

• If a customer name is in the filter context

• If the data model is complete

How can you prevent the 'Top' label from appearing in the total line of a report?

• By using a different data model

• By applying a filter to the report

• By wrapping the logic in an IF condition

• By changing the label name

What is the benefit of using conditional statements in the classification logic?

• To enhance the display of results

• To increase the speed of data processing

• To improve the accuracy of data entry

• To reduce the size of the data model
