The archeological site of Tara is more than 4000 years old. Tradition states that Tara was the seat of the high kings of Ireland. Because of its archeological importance, Tara has received extensive study (Reference: Tara: An Archeological survey by Conor Newman, Royal Irish Academy, Dublin). Suppose an archeologist wants to estimate the density of ferromagnetic artifacts in the Tara region. For this purpose, a random sample of 55 plots, each of size 100 square meters, is used. The number of ferromagnetic artifacts for each plot is determined.

quantitative
The number of plots used in the study is 55.
Each plot has a size of 100 square meters.
To estimate the density of ferromagnetic artifacts in the Tara region, the number of ferromagnetic artifacts is determined for each plot.
The density of artifacts can be calculated by dividing the total number of ferromagnetic artifacts by the total size of the plots.
The number of ferromagnetic artifacts per 100 square meters can be calculated by dividing the total number of ferromagnetic artifacts by the total number of plots.
To estimate the density of ferromagnetic artifacts in the Tara region, the archeologist uses a random sample of 55 plots, each measuring 100 square meters.
1. Number of plots: The archeologist has selected 55 plots for the study.
2. Size of the plots: Each plot measures 100 square meters.
3. Density of artifacts: The archeologist wants to estimate the density of ferromagnetic artifacts in the Tara region. This refers to the number of artifacts per unit area (in this case, per 100 square meters).
4. Number of ferromagnetic artifacts per 100 square meters: To estimate the density, the number of ferromagnetic artifacts is determined for each plot, and it is measured in terms of how many are found within an area of 100 square meters.
5. Number of plots as well as size of the plots: By selecting 55 plots of equal size (100 square meters each), the archeologist ensures that the sample is representative of the Tara region and can provide an estimate of the density of ferromagnetic artifacts in that area.
