Catching errors in your A/B tests is easier when you know what you’re looking for. These are some common causes of sample ratio mismatch: ✔️ Technical Issues ✔️ External Factors ✔️ Configuration Errors ✔️ Variation Bias Fortunately, SiteSpect can help you address these issues before they affect your experiments. Find out how to fix sample ratio mismatch in our blog here: https://hubs.la/Q02M1clZ0 #abtesting #hybridexperimentation #experimentation

You might see a runtime exception like this one "using generic type IContract<T> requires 1 type argument" (at the moment when runtime needs a resolved and registered concerte implementation of IContract<T>). So, how to return resolve this exception?". The solution:- Create a none generic parent contract as a super type for the erroneous generics one. Move the mothod (function) that accepts/uses the generic type <T> to the parent interface (without mentioning <T>). The child contract will still accept generics but it will be a blank contract with no methods. Check below code snippet. public interface IContract { void Foo(int x); } public interface IContract<T> : IConract where T : class { }

Last year, we introduced Experimental Retries, giving you control over test flakiness thresholds. You can specify what level of test flakiness should pass or fail by setting fine-tuned thresholds for retries based on what’s important to you: 👉 Detect flake but pass on a threshold that you configure 👉 Detect flake but always fail, to ensure your team is notified Take Experimental Retries for a spin: https://lnkd.in/e9q73hHZ

The Array.prototype.findLastIndex method returns the index of the last element in the array that satisfies the provided testing function. If no elements satisfy the testing function, it returns -1. Suppose we have an array of numbers and we want to find the index of the last even number in the array.

New functionality released this week to FastTest, our powerful platform for online #assessment! https://lnkd.in/gvu4qD-C - Capturing the IP address of candidates that review their submitted test, and providing it to administrators in a report - preventing a candidate with sharing the review link to friends - If an adaptive test is fixed-length, display the remaining items (impossible of course for variable-length CAT) - Unscored items seeded in linear-on-the-fly testing (LOFT) - Additional item metadata available during test assembly

Have you wondered if is there any experiment that allows us to peek at the results during the experiment process? I think you need to know about "Sequential Testing". Sequential Testing focuses on two kinds of problems: peeking results during the process, and monitoring continuing/streaming data from deviating. More about sequential testing is in my medium, please enjoy.

Blog on Root Cause Analysis... Why the results are mismatching? A medium reference laboratory is having more than 1500 samples in a day. The laboratory works round the clock and collects the samples from an 80 km radius. The laboratory has cloud-based software connectivity to lower the TAT. They are using pre-barcoded sample tubes for better sample traceability... Continue Reading Here... https://zurl.co/hvzB #agappe #agappeblogs #rootcauseanalysis

The AND function can be used with the IF function to test multiple conditions: AND function Returns TRUE if all arguments evaluate to TRUE, and FALSE if one or more arguments evaluate to FALSE. IF function Performs a logical test and returns one value if the test evaluates to TRUE, and another value if the test evaluates to FALSE. The AND function can be used as the logical_test argument of the IF function. The syntax for this is: AND =IF(AND(Something is True, Something else is True), Value if True, Value if False) follow for more DswithDs informative or not like and share.....
