Use Cases

  • By analyzing the population standard deviation for page load times and response times, you can identify patterns that may cause slow or inconsistent user experiences, pinpointing potential performance bottlenecks.

Tips

  • When working with data representing an entire population (full population data), opt for the List Standard Deviation action to accurately measure the variability. However, if you are dealing with a sample from a larger population, do NOT use the List Standard Deviation action.
