groups such as Chicanos fit the Afrocentric paradigm? Is the Afrocentric approach bound by the limitations of its new disciplinary context, or does it offer something unique which may
What is a 'Z-Score'. A Z-score is a numerical measurement of a value's relationship to the mean in a group of values. If a Z-score is 0, it represents the score is identical to the mean score. Z-scores may also be positive or negative, with a positive value indicating the score is above the mean and a negative score indicating it is below the mean. Positive and negative scores also reveal the number of standard deviations the score is either above or below the mean.
A positive z-score means the data value is larger than the mean. If a data value has a z-score of 2, that tells us that this data value is 2 standard deviations larger than the mean. A negative z-score means the data value is smaller than the mean. If a data value has a z-score of â3.1, then this data value is 3.1 standard deviations smaller than the mean. A z-score of zero means that the data value equals the mean. For example, consider a data set with a mean of 50 and a standard deviation of 2. If a data value also is 50, then the z-score is:
