Multiply each number by the previous number and increase the multiplication value by 2 each time. The series is made using 2 different operations (multiplication and division). It can be shown that the SPRT is optimal in the sense that it minimizes the average sample size before a decision is made among all sequential tests which do. The common difference between each number in the sequence is 3 Such as:Ī) A common difference between each number There are a number of ways to construct the questions to make them easy or hard.Sequences are based on arithmetical operations such as, multiplication, division, subtraction.There should be only 1 possible correct answer from the options provided.Number series tests are normally multiple choice with only 1 correct answer and some answer options that could be distractors.Learn more about all the other FlexiQuiz features and plans.The FlexiQuiz automation tool can randomly select questions from the bank for inclusion in future tests Plus, Premium plan members can save questions in the question bank for future use.Instant marking and sharing results - you define the metrics and who is notified.Learn more about our features to keep your test secure Secure access to your test by adding a unique ID (such as a candidate number) for people to gain access.Flexibility to take the test at any time, any place on desk top, mobile or tablet devices.A choice of question types including multiple choice (most frequently used) or fill in the blanks.Timed tests to create exam like conditions.You can create challenging, measurable tests to identify the best candidate for your organization. A number sequence consists of a number series, with one missing number that respondents need to logically identify.įlexiQuiz software helps you build your own numeracy tests that can be configured to meet your specific needs. Number sequences are often part of numerical aptitude, psychometric and IQ tests to identify the respondent's ability with numbers. I personally prefer the second option for big things, and the first one for simple/short ones.Home | Help Guides: Number sequence testing Which strategy to use would depend on your goals and the size of the scenario. Another strategy is to generate multiple tests in which you test the individual steps: test 1 does A test 2 does A->B (but doesn't care if A is ok) test 3 does A->B->C (but doesn't care if A and B are ok) and so on. Let's say for example that you want to test D, but D needs C, and then C needs B, and finally B needs A one strategy would be to generate a test in which you would do A->B->C->D. In case there are variations, then you would have multiple tests. Now, if you want to test a complete flow of a system, I would recommend you to put that inside one unique test. No matter where/when this is done, the important thing is that you assume that all that's needed to generate that status works as expected, so you just focus on what you are testing. If you need preconditions on your tests you can include them in: 1) before all tests, 2) at start of the test suite, 3) before your specific test, 4) inside your specific test. In case any part of the sequence fails, then the rest of the tests fail, so it really doesn't make much sense to have them sepparate (they could be just one test). That's why sequential test-cases should be avoided. Tests are meant to be atomic, in the sense that they should NOT rely on a status that was generated by a previous test.
