What is the difference between a hypothesis a theory and a conclusion drawn from hypothesis testing?
A hypothesis is a suggestion of a way to explain something. If the hypothesis is tested and confirmed, it can advance to the status of theory. The conclusion of testing a hypothesis will be either that the hypothesis is confirmed, or it is not confirmed.
How would one explain the coefficient of determination?
The coefficient of determination, is when someone tries to predict the outcome of the testing of a hypothesis, or their guess at to what will happen. It helps determine how well outcomes are determined beforehand.
What is difference between testing methods testing types testing levels testing techniques?
Hi All, I think the answer for this question is, Testing method :Verification(review) and Validation Testing types : Basically static and dynamic-> in dynamic testing further can be classified into structural(white box) and functional(black box) testing Testing Technique : in white box testing we have 1) loop coverage 2)statement coverage 3) condition coverage 4) decision coverage in black box testing we have 1) Equilance partioning, 2)boundary value analysis 3) error guessing Testing Levels : Unit testing, integration testing systemtesting , Acceptance testing
What is stochastic testing?
Stochastic testing is the same as "monkey testing", but stochastic testing is a lot more technical sounding name for the same testing process. Stochastic testing is black box testing, random testing, performed by automated testing tools. Stochastic testing is a series of random tests over time. The software under test typically passes the individual tests, but our goal is to see if it can pass a large number of individual tests.
List the 5 steps of hypothesis testing and explain the procedure and logic of each Specify the null and alternative hypothesis Select a significance level typically 0.05 or the 0.01 level is used?
what is an example of a hypothses about compensation?
Explain why eddy current testing can be carried out on all the metals whereas magnetic particle testing can only be carried out on ferromagnetic materials?
Eddy current testing can be carried out on all the metals provided the metals should be able to conduct the current. No need that it should have magnetic property. Magnetic praticle testing can be carried out only on ferromagentic materials since it works on magnetic permeabiltiy principle. Materials which has poor magnetic permeability is not able to test with MPI. This is very simple answer.
What are the non destructive tests for welding?
Magnetic Particle Testing, Ultrasonic Testing, Dye Penetrant, Radiography Testing (x-ray), Visual Inspection
What has the author Carl E Betz written?
Carl E. Betz has written: 'Principles of magnetic particle testing'
What is the formula to compute the amperage of a ring in magnetic particle testing?
You can see the details in ASTM 1444E or materials of ASNT. John Nguyen
What is mpi?
Magnetic Particle Inspection - An NDT (Non Destructive Testing) method primarily used to find surface breaking flaws in ferrous materials.
What is magnetic particle testing in NDT?
This ndt method is used for the detection of surface an near to surface discontinuities in ferromagnetic materials,by applying a magnetic field and a medium sensitive to areas of magnetic flux leakage.This medium will be attracted,and held,to the part surface(by the flux leakage)and the visual indication of a discontinuity then interpreted by a qualified operator.
What is the principle of universal testing machine?
Utm works on force and elongation/deformation principle.
What is the basic principle of radiographic testing?
what is the principal of radiography
How do you explain welding defects and explain its testing?
Defects can be varied and classified as critical or non critical. Porosity (bubbles) in the weld are usually acceptable to a certain degree. Slag inclusions, undercut, and cracks are usually non acceptable. Some porosity, cracks, and slag inclusions are visible and may not need further inspection to require their removal. Small defects such as these can be verified by Liquid Penetrant Testing (Dye check). Slag inclusions and cracks just below the surface can be discovered by Magnetic Particle Inspection. Deeper defects can be checked thru X-raying.
Is the definition of criteria?
A standard or principle for evaluating or testing something.
What is the main tool for autoimmune disease testing?
The principle tool, however, for authenticating autoimmune disease is antibody testing
Explain the basic terms of used in Software testing?
Useding in software testing: what an outstanding idea
