This article explains how to make tests of hypothesis about experiments with more than two possible outcomes (or categories). Such experiments‚ called multinomial experiments‚ possess four characteristics. Note that a binomial experiment is a special case of a multinomial experiment. An experiment with the following characteristics is called a multinomial experiment. 1. It consists of n identical trials (repetitions). 2. Each trial results in one of k possible outcomes (or categories)‚ where k

Introduction Tensile test is also known as tension test. It is material’s strength test where pulling force is applied from two ends. It is very important mechanical property evaluation test which provides fundamental properties like strength‚ stiffness‚ elastic limit‚ ultimate tensile strength etc. in this test‚ test object are standard size and shape but different material‚ then direct comparison of properties of those materials can be made. We had used standard “dumb-bell” shaped

Sample Questions for the Computer-Based Test The questions on the following pages are similar to those that will be presented in the actual test. Here is an example. On the computer screen‚ you will see: Listening QUESTION DIRECTIONS — Part A In Part A of the Listening section‚ you will hear short conversations between two people. In some of the conversations‚ each person speaks only once. In other conversations‚ one or both of the people speak more than once. Each conversation is followed by

trying to find out what is in a substance. In this case we are using the flame test to try and discover what is in 4 unknown sample solutions that we have been given this is done by cross referencing the colour of the flame with 6 known solutions we test beforehand. Aim- In this experiment we are attempting to distinguish what substances are in the 4 unknown solutions by cross referencing with the 6 known solutions we test beforehand. Assumption- Not applicable for this experiment as we would have

Research Methods Test 1.) Triangulation in a qualitative research study is used to formulate valid and reliable conclusion and can use different methods to search or to gather data. Collecting and comparing information from different aspects can confirm reliability as well as validity. Triangulation in qualitative research not only involves the researcher‚ but gives peer researchers a chance to view how the study was conducted and interpret it in their own way which can influence the final
