Is a z test or t test used more often?
t test, because the z test requires knowing the population standard deviation and that's rare. The t test embodies an estimate of the standard deviation.
The wisc IQ test is an example of a percentile rank a raw score a criterion-reference test or a standard score?
standard score
What is the calculated numerical value that is compared to a table value in a hypothesis test called?
It is the test statistic.
What is the spt number?
That is the standard penetration test.
Is alpha the probability that the test statistic would assume a value as or more extreme than the observed value of the test?
Alpha is the probability that the test statistics would assume a value as or more extreme than the observed value of the test, BY PURE CHANCE, WHEN THE NULL HYPOTHESIS IS TRUE.
What is magnetic balance test of transformer?
The Magnetic Balance test is conducted on Transformers to identify inter turn faults and magnetic imbalance.
What is the meaning of magnetic balance test?
Magnetic balance test is performed on transformer to check, whether the core and windings of the transformer is balance position or not. Magnetic Balance is a test of Critical use as it helps us to enhance the efficiency and life of transformers.
What is the importance of standard consistency test?
by standard consistency test we determine standard consistency of cement which is denoted by p. as we know standard consistency value for a cement its value is used for making the paste for determining setting time, soundness, compressive strength of cement
How can balance be tested?
flamingo balance, balance board test, one legged stand, standing balance test
What is an N value in soil report?
N Value is the parameter indicating the compaction of the soil . N value decided from standard penetration test(spt)
Why Y phase is high in YNyn0 when doing magnetic balance test?
because y phase is y phase ...it is not b phase or R phase so it is high
How do you test materials as magnetic or non-magnetic?
I use a "magnet".

What is sbc of soil?
SBC is the safe bearing capacity of a soil, beyond this value if soil is loaded, it will fail to bear the load applied on it and will fail. Its value can be found out by standard penetration test, plate load test or cone penetration test.
Is the cst California standard test or California state test?
California standard test
What is measured by the numerator of the z-score test statistic?
The z-score, for a value z, is the probability that a Standard Normal random variable will have a value greater than z.
Are there any household items that can be used to test if gold is real?
You can use a magnet to test if the piece of "gold" is magnetic or not. Gold is not magnetic, so if it is attracted then it is not real.
