have tried to show the application of the statistical tools upon the general index or all share index of DSE for the year 2003. To achieve the purpose‚ first of all we have collected the data for the year 2003. Then we have edited the data for the accuracy test. As we have collected the secondary data directly from the DSE the accuracy of the information is in a reasonable standard. Then we have tried to show the application of the statistical tools which are presented in the body part of the

Test Validity 1 Introduction Validity is arguably the most important criteria for the quality of a test. The term validity refers to whether or not the test measures what it claims to measure. On a test with high validity the items will be closely linked to the test’s intended focus. For many certification and licensure tests this means that the items will be highly related to a specific job or occupation. If a test has poor validity then it does not measure the job-related content and competencies

Physiological measurements Body Temperature: This is the body ability of the body to generate and get rid of heat. It is measured via the mouth‚ ear‚ forehead and armpit. The hypothalamus in the brain regulates body temperature. Body temperature is maintained by constant burning of fuel in cells. It burns carbohydrates and fat. This constant burning of fuel is a chemical reaction of carbohydrates/fat with oxygen. This will be converted to CO2‚ water and heat and it is due to that heat the body

In this case discussing both projective and self-report personality tests in terms of their reliability and validity in a social context. These tests are extremely useful in multiple ways such as calculating future behaviour and recognizing future behaviours according to Plotnik (2002). There are so many personality tests available for use but this essay

DISCUSS ISSUES RELATED TO THE RELIABILITY OF A PSYCHOLOGICAL MEASURE Part of long question: The activities dealing with the basic principles of psychometric theory. 6. Stage 6: Evaluating psychometric properties and establishing norms 6.1 Establishing Reliability Scheme: 1. What is meant by a person’s observed score? True score and error variance in a test score? 2. The typical sources of true variance and error variance in a test score. 3. The interpretation of a reliability coefficient and how large

Nominal Level of Measurement The nominal level of measurement is the lowest of the four ways to characterize data. Nominal means "in name only" and that should help to remember what this level is all about. Nominal data deals with names‚ categories‚ or labels. Data at the nominal level is qualitative. Colors of eyes‚ yes or no responses to a survey‚ and favorite breakfast cereal all deal with the nominal level of measurement. Even some things with numbers associated with them‚ such as a number

Software reliability modeling has‚ surprisingly to many‚ been around since the early 1970s with the pioneering works of Jelinski and Moranda‚ Shooman‚ and Coutinho. The theory behind software reliability is presented‚ and some of the major models that have appeared in the literature from both historical and applications perspectives are described. Emerging techniques for software reliability research field are also included. The following four key components in software reliability theory and modeling:

How To Make Tutus STEP 1. Take measurements. Have the tutu-wearer-to-be stand still‚ with their backs straight. With a measuring tape‚ measure around the waist with a measuring tape. Measure from the waist to the part of the leg where the tutu skirt should end. Most tutus fall between 11 in. (28 cm) (58 cm) from the waist. STEP 2. Make the elastic waistband‚ cut a piece of ½ inches (1.27 cm) elastic about 4 inches (10 cm) shorter than the waist measured. Sew the ends of the elastic together
