Looker Studio Function :ASIN
Category: Arithmetic function
Looker Studio’s ASIN function plays a crucial role in advanced data analysis. Commonly used for data distribution analysis, customer segmentation, and strategic decision-making, this trigonometric function helps businesses unlock deeper insights from complex data sets.
Purpose of the ASIN Function
1. Data Distribution Analysis :
The ASIN function helps map nonlinear distributions by transforming proportion values. This is useful for analyzing behavior patterns or detecting outliers in a dataset that includes normalized values like percentages.
2. Customer Segmentation :
By applying ASIN to proportion-based customer metrics (like engagement scores), you can create more nuanced customer segments. This helps personalize marketing strategies and optimize user experience.
3. Decision Making :
Apply Log10-transformed data to models and dashboards to improve business decisions. It supports deeper insights by revealing underlying trends that raw data might obscure due to scale distortion.
Type of Calculation:
| Use Case | Description |
|---|---|
| Performance Benchmark | Use ASIN to normalize KPIs before comparison across departments or regions. |
| Customer Segmentation | Helps in adjusting engagement scores for more accurate group classifications. |
| Time Series Analysis | Transforms cyclical or sinusoidal data for trend detection and smoothing. |
ASIN(number)
| Parameter | Type | Description |
|---|---|---|
| number | Number | A numeric value between -1 and 1 (inclusive) |
How Does the ASIN Function Work?
The ASIN function calculates the inverse of the sine of a number, essentially answering: What angle (in radians) has a sine equal to this value? It runs directly within Looker Studio’s calculation engine and outputs real-time results when applied to a compatible numeric field.
When Should You Use ASIN?
Use the ASIN function when:
Working with normalized or proportional data (e.g., bounce rate, CTR).
Building mathematical models involving sinusoidal transformations.
Creating custom segmentation based on behavioral scoring.
Example of ASIN with Result
Example 1: Basic Usage
ASIN(0.7)
Example 2: Column Usage
ASIN(Engagement_Score)
Example 3: Handling Decimals and Scientific Notation
ASIN(1E-2) => 0.01000017 radians
Example 4: Combining with Other Functions
ROUND(ASIN(CTR), 2)
Tips and Tricks
Validate input range: Ensure values are between -1 and 1.
Use radians-to-degrees conversion if needed:
DEGREES(ASIN(value))Layer with segmentation logic using
CASEorIFfunctions.Combine ASIN with smoothing functions for clean visualizations.
Label transformed fields clearly to avoid confusion with raw metrics.
ASIN stands for arc sine, which returns the angle (in radians) whose sine is the given number.
No, the ASIN function only works for values within the -1 to 1 range. Inputs outside this will return errors.
Common use cases include performance benchmarking, data transformation, segmentation, and time-series smoothing.
Use the DEGREES() function:
Yes, ASIN is fully compatible with Looker Studio’s calculated fields and custom metrics.
