Using a computer to perform statistical analysis. 2004

SPSS, and other statistical packages, make it easy to perform complex statistical analysis, but even simple analysis such as tables and graphical output are much simpler using such a package. Use of such a package does, unfortunately, also allow you to perform meaningless statistics and incorrect statistical tests, and give misleading or wrong interpretations. You will still need to understand some statistics, but you will not need to be able to compute the results yourself. A statistics package allows you to concentrate on the appropriateness of a test and interpretation of the results. It does not do the whole job for you.

D011237	Predictive Value of Tests	In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

D015982	Bias	Any deviation of results or inferences from the truth, or processes leading to such deviation. Bias can result from several sources: one-sided or systematic variations in measurement from the true value (systematic error); flaws in study design; deviation of inferences, interpretations, or analyses based on flawed data or data collection; etc. There is no sense of prejudice or subjectivity implied in the assessment of bias under these conditions.

D016009	Chi-Square Distribution	A distribution in which a variable is distributed like the sum of the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another.
