Exercise 14: Qualitative Anion Tests PURPOSE: The purpose of this experiment is to identify some commonly occurring anions & to study some of the reactions used for their identification. PROCEDURE: You must first determine to which of the three groups the various anions belong. Since no two people observe the same event in exactly the same way it is important to also conduct specific confirmation tests on the known samples of each anion. This information will help identify the anion

Date: 20/03/13 Flame Test – Investigating Compounds Aims To identify the presence of a relatively small amount (ie low concentration) of a metal ion in a compound. Method 1. Clean a platinum or nichrome wire by dipping it into concentrated hydrochloric acid. 2. Hold the platinum or nichrome wire at the hottest or blue part of a non-luminous Bunsen flame. 3. Repeat until the wire does not produce any colour in the flame (note: do not touch the wire‚ as salt in sweat will produce

Nonparametric tests" simulation‚ I realize there were a few things to take into consideration when analyzing a problem. This particular exercise wanted to know the differences and causes of the variation. In order to resolved the solution‚ an individual or whoever is conducting the analysis will need to know what type of test to used‚ decide if the null hypothesis should be rejected or not‚ and make recommendation based on the collected data. Due to two parameters‚ ANOVA and the Krusla-Wallis Test (Nonparametric)

RSAMI – GROUP II ‘Testing the competence of the Stroop test when taken by undergraduate students with pairs of words and colours that are congruous‚ incongruous and semantic.’ ABSTRACT This experiment was conducted using a semantic variation in addition to the original Stroop test to determine the difference in reaction times when applied to congruent‚ incongruent and semantic words and colours. The experiment was conducted with a sample of 20 (17 female‚ 3 male) junior freshman psychology

administration‚ and scoring of the test the next step is to perform an interpretation of the test. While interpreting the test the interpreter may find that‚ there are a few test bias that may have caused the scores to be high or low within a certain group causing the test to be unfair. Test bias and test fairness are two topics that individuals will continue to debate for years to come. Salkind (2013) described Test fairness as a very sensitive of use of examinations‚ quizzes‚ tests‚ etc. and social values
