Is A negative z score is unusual?
In general, the answer is no, both negative and positive z score values should be expected. A z-score (or standardize score) is the raw data value minus the mean and then this result divided by the standard deviation. If the data can be considered normally distributed and a random sample is taken from a population, then as the sample size becomes large, approximately half the z-scores should be negative and half of the z-scores should be positive. There are some exceptions. Small data sets may have only positive values. A non-normal (skewed) distribution if skewed to the right, may have, after normalizing, may have a higher portion of z scores as positives.

What shows a correlation which may be positive or negative between two sets of data?
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
In statistics what is homogeneous data?
this is data which is within the same range i.e : Grouped data (set of numbers) It may be negative(left) or positive (right)
What is difference between unsignedint and signedint in c language?
Unsigned int does not have a sign, meaning that it can be zero or a positive number in the range of data type (int). Signed data has a sign and can be positive, zero or negative.

What does a negative z value mean?
Negative z value means that the raw dat is below the mean, if z value is positive it means that the raw data is above the mean.
