If the variability of a set of data is very small, then the sample variance may be negative.
Sample Variance
A measure of the dispersion or variability of a sample dataset, representing how much the data points differ from the sample mean.
- Realize the essential importance of variation measures (standard deviation, variance) and central averages (mean, median, mode) in data encapsulation.
- Outline the computation process for variance and standard deviation, and their significance in the context of data analysis.

Final Answer :
False
Explanation :
The sample variance cannot be negative, as it is a measure of variation and is always non-negative. If the variability of the data is very small, then the sample variance will be close to zero, but it cannot be negative.
