Variability in Fish Population Across Regions
Hard Data Representation Understanding Graphs And Tables
A marine biologist conducted a study to evaluate the population dynamics of a certain fish species across three different oceanic regions over five years. The data was recorded annually and is summarized in the following table:
| Year | Region A (individuals) | Region B (individuals) | Region C (individuals) |
|---|---|---|---|
| 1 | 150 | 200 | 250 |
| 2 | 180 | 210 | 220 |
| 3 | 160 | 190 | 300 |
| 4 | 200 | 245 | 310 |
| 5 | 220 | 215 | 290 |
Based on the data in the table, which region experienced the most variability in fish population over the five-year study period?
