Exact or even close population counts are not known. It is thought that Pompeii had a population somewhere between 12,000 and 15,000 and Herculaneum a population between 4,000 and 5,000. Very few remains have been found within Herculaneum. Most of the remains have been found on the beach.
Independence. An independent variable is one is manipulated by the researcher. It is like the knob on a dial that the researcher turns. In graphs, it is put on the X-axis. A dependent variable is one which changes as a result of the independent variable being changed, and is put on the Y-axis in graphs.ndependence.

Some researchers observe what changes occur while they are passive to determine the dependent variable. In these cases, researchers merely record the measurements and results of the dependent variable without interference. Conversely, the independent variable is thought to be the variable acted upon.Active independent variables require researchers to act, such as adjusting a temperature or dose.n these cases, researchers merely record the measurements and results of the dependent variable without interference.
