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.

Summary of Differences. 1  In science, for one independent variable, there may be more than one dependent variable. 2  The value of an independent value can be changed. 3  The independent variable is the value which is manipulated in an experiment. The dependent variable is the value observed by the researcher during an experiment. Knowing the differences between independent and dependent variables will help as you as you sharpen your problem solving skills and continue to explore new concepts within the fields of mathematics and the science.
