	Critical value - Wikipedia, the free encyclopedia
		In differential topology, a critical value of a differentiable function between differentiable manifolds is the image of a critical point.
		In statistics, a critical value is the value corresponding to a given significance level.
		This cutoff value determines the boundary between those samples resulting in a test statistic that leads to rejecting the null hypothesis and those lead to a decision not to reject the null hypothesis.

	Critical exponent - Wikipedia, the free encyclopedia
		Critical exponents are observed in second-order phase transitions.
		The most accurately measured value of α is −0.0127 for the phase transition of superfluid helium (the so-called lambda-transition).
		The value was measured in a satellite to minimize pressure differences in the sample (see here).

	Critical Value (Site not responding. Last check: 2007-11-03)
		It is the value that a test statistic must exceed in order for the the null hypothesis to be rejected.
		For example, the critical value of t (with 12 degrees of freedom using the 0.05 significance level) is 2.18.
		This means that for the probability value to be less than or equal to 0.05, the absolute value of the t statistic must be 2.18 or greater.

	1.3.6.7.4. Critical Values of the Chi-Square Distribution
		For upper one-sided tests, the test statistic is compared with a value from the table of upper critical values.
		For two-sided tests, the test statistic is compared with values from both the table for the upper critical value and the table for the lower critical value.
		If the test statistic is greater than the upper critical value or less than the lower critical value, we reject the null hypothesis.

	MGH Lab Handbook - Critical Values List
		Critical results are defined as results that, if left untreated, could be life threatening or place the patient at serious risk.
		Critical results are those results from a clinical specimen that upon analysis are determined to be "critical" whether the specimen was submitted as a routine or stat specimen.
		Critical test results will be communicated to the responsible licensed caregiver within 40 minutes from the time the result is available in the laboratory.

		The next step is to determine the critical value associated with an area of 0.025 in the right tail or in the left tail.
		So, the critical value on the right side is 1.96 and on the left side is –1.96.
		So, since the white part has a value of 0.025 and the total area under the curve is equal to 1.0, then the shade area is 1.0 – 0.025 = 0.975.

		Critical values may imply a life-threatening situation for the patient and are brought to the immediate attention of the physician and/or the patient care area responsible for the patient.
		The current critical values were established by consensus of attending physicians and/or medical directors of the hospital's critical and emergency care units, approved by the Director of Rush Medical Laboratories, and are reviewed and changed as directed by these physicians.
		Once critical values for a test is established, laboratory staff are required to follow protocol for notification when critical results are obtained.

	Statistics Glossary - Hypothesis Testing
		The critical value(s) for a hypothesis test is a threshold to which the value of the test statistic in a sample is compared to determine whether or not the null hypothesis is rejected.
		The critical value for any hypothesis test depends on the significance level at which the test is carried out, and whether the test is one-sided or two-sided.
		In other words, the critical region for a one-sided test is the set of values less than the critical value of the test, or the set of values greater than the critical value of the test.

	4.2 Consequences of axioms: critical points, sets, and values.
		NOTE: The location and precise value of the disambiguation point and hence the critical value is dependent on the interpolation function, but the existence of this criticality in the face is not.
		The topological changes at a criticality, as the threshold is decreased through a (non-maximal) critical value, are completely characterized by the number of distinct sets of Highs that become connected.
		The point is that we can divide the entire range of possible function values into disjoint, critical value-free intervals, so that no topological change in the level sets can occur as the threshold is varied within one of the intervals.

		These critical values may be indicated in the procedure manual and /or in a separate manual or policy.
		The requirement for the establishment of "critical values" is most readily evident where quantitative results are generated, but assays yielding qualitative results can also be considered as potentially yielding "critical" results.
		The comment that situations are covered by information in policies/procedures other than the critical value procedure begs the question in that the CAP checklist question note already states that the list need not be in a separate procedure.

	Using a Critical Value Table for Pearson's r (Site not responding. Last check: 2007-11-03)
		Use the critical value table to find the intersection of alpha.05 (see the columns) and 25 degrees of freedom (see rows).
		The value found at the intersection (.381) is the minimum correlation coefficient r that you would need to confidently state 95 times out of a hundred that the relationship you found with your 27 subjects exists in the population from which they were drawn.
		When using the critical value table, use the absolute value of your r (in other words...ignore the negative sign of your r if you have a negative relationship).
