Question

In each simulation trial, you changed the number of
people and measured the number of
people in the population.

Answer 1

That sentence is redundant and a bit unclear. Do you mean you changed the starting population and then measured the resulting population after running the simulation, or something else? Here are several clearer rewrites depending on what you intend:

- If you varied the initial population and measured the outcome after a fixed time:
"In each simulation trial we varied the initial number of people and recorded the population size after T time steps."

- If you changed the number of agents per trial and measured the immediate population:
"For each trial we set a different number of agents and measured the resulting population size."

- If you adjusted population size continuously during the trial and measured at intervals:
"During each trial we changed the number of people and tracked the population size over time."

- If you mean you tested different population sizes to study their effect on dynamics:
"We ran trials across a range of population sizes and measured the resulting population dynamics for each."

If you’re writing a methods section, add specifics: the parameter varied (e.g., initial N), range and step, number of replicates per setting, measurement time(s), and summary statistics. Example full sentence:

"We ran 100 simulation trials, varying the initial population N from 10 to 100 in steps of 10; for each N we ran 50 replicates and recorded the population size after 1,000 time steps (reported as mean ± SD)."

Tell me which meaning you want and I can produce a single polished sentence or a short methods paragraph.
