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.

Experimental and Nonexperimental Research. The basic building blocks of quantitative research are variables. Variables (something. that takes on different values or categories) are the opposite of constants (something that. cannot vary, such as a single value or category of a variable).
