The expression 
is recognizable as the formula for:
A) the sample variance, computed from ungrouped data
B) the population variance, computed from ungrouped data
C) the sample variance, computed from grouped data
D) the population variance, computed from grouped data
E) the population variance, computed from ungrouped or grouped data
Population Variance
A measure of the dispersion of a set of data points in a population, calculated as the average of the squared deviations from the mean.
Sample Variance
A measure of the dispersion or spread of a set of data points in a sample, illustrating how much the data differ from the mean.
Grouped Data
Data that has been organized into categories, classes, or intervals, often to simplify analysis and find frequency distributions.
- Acquire knowledge and utilize methods concerning variance and standard deviation applicable to both sample and population.
