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

Introduction For the last week‚ specific tests had to be applied to determine the unknown solid that was given out randomly. Physical tests‚ solubility test‚ characteristic tests‚ NMR spectrums‚ and IR spectrums were all utilized to distinguish the identity of the solid. These assessments and a couple additional tests will be utilized again to determine the unknown liquid that was given to us in class. The other characteristics that will be looked at will be the boiling point‚ refracted index‚ and

SCHOOL OF CIVIL ENGINEERING ABSTRACT This report describes a compression test on concrete columns. The main aim of the tests was to illustrate the ultimate strength limit state of reinforced concrete columns in combined bending and compression and to demonstrate the influence of slenderness on the ultimate load capacity. Test methods are described. It was found that the concrete columns exhibited complicated behaviour‚ and had a squash load point of 342.7KN and moment at 0 KN

The flexed-arm hang test is a physical fitness test used to measure upper body strength and endurance. It is done by timing how long one can remain hanging with the (1) chin above the bar . It is popular as a military training exercise. The United States of America Marine Corps members have to pass the Physical Fitness Test (PFT) twice a year. This test includes the flexed-arm hang as an exercise used to gauge upper body endurance. In order to pass the test‚ the marines need to hang for at least

year 1968 Walter Mischel conducted the marshmallow test to see children’s abilities to control their willpower‚ to test if they had the ability to control urges such as the addiction to sugar. The test was used to show that a person’s willpower played a large role in their ability to be successful in academics and many other aspects of life. Is willpower truly the answer to predict one’s success? Or is it just a mere coincidence? The marshmallow test started in a room with a child from the age range

Fitness testing Task 2 Hand grip test: Suitability: The hand grip test is suitable as it is a straight test to test the forearm strength and gives a good indication of your strength. Reliability: the dynamometer may need to be calibrated regularly to ensure consistent results. Having consistent technique and adequate rest is required to ensure reliability. Validity: The validity of this test as a measure of general strength has been questioned‚ as the strength of the forearm muscles does not
