Question

What problems are related to the aggregation of variance data?

Answer 1

The variance aggregation creates problems because it shows diversion of the statistical values from mean value.

Problems are likely to exceeds to range of potential values and grows indefinitely when the possible values is finite.

The errors in the production process exceeds of the standards on aggregation of variance or the mean of production standard.

The standard deviation of the production standards increases on the aggregation of the variance.

Thus, problems of the production rejection increases on the aggregation of the variance data.
