is a data set with same variables but observed from different group of respondents
Pooled variance is a method for estimating variance given several different samples taken in different circumstances where the mean may vary between samples but the true variance (equivalently, precision) is assumed to remain the same. A combined variance is a method for estimating variance from several samples, given the size, mean and standard deviation of each. Mathematically, a combined variance is equal to the calculated variance of the set of the data from all samples. See links.
mean does not mean the center of the data
The mean of a set of data is the sum of that data divided by the number of items of data.

Pooled resources and skills refer to the collective sharing of resources and expertise among a group of individuals or organizations. By combining resources and skills, the group can achieve more than each member could alone, leading to increased efficiency and effectiveness in solving problems or achieving common goals. This pooling of resources and skills is often seen in collaborative efforts such as partnerships or consortiums.

what do you mean by data assembly?
no. Some mean is a number from the data but some mean is completely different from its data.
