Glossary Term
A statistical method to test if observations are significant or due to chance. It proposes that no statistical significance exists in a set of given observations and attempts to show that no variation exists between variables or that a single variable is no different than its mean. It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis.
Glossary Term
The ratio of the odds of an event occurring in one group to the odds of it occurring in another group, or to a sample-based estimate of that ratio.
Glossary Term
A sequence of nucleotides in that contains no termination codons and so can potentially translate as a polypeptide chain.
Glossary Term
The concentration of osmoles of solute per kilogram of solvent present in a sample.
Glossary Term
An observation in a data set that is numerically distant from the rest of the data.
Glossary Term
A measure of the probability that a result happened by chance. The lower the p-value, the more likely it is that the result was caused by phenomenon of interest.
Glossary Term
A method used to test whether the mean difference between pairs of measurements in a related group are significant.
Glossary Term
In statistical inference procedures (hypothesis tests and confidence intervals), parametric procedures are those that incorporate assumptions about population parameters.
Glossary Term
A measure of the correlation of two variables X and Y measured on the same object or organism, that is, a measure of the tendency of the variables to increase or decrease together. It is defined as the sum of the products of the standard scores of the two measures divided by the degrees of freedom.
Glossary Term
Any of the 99 numbered points that divide an ordered set of scores into 100 parts each of which contains one-hundredth of the total.
Glossary Term
Quantity of dimension one used to express on a scale from 0 to 14 the amount-of-substance concentration of hydrogen ion of dilute aqueous solution, calculated as the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter.
Glossary Term
The assemblage of traits or outward appearance of an individual. It is the product of interactions between genes and between genes and the environment.
