what did you actually measure as dependent variable?

Moreover, it is not quite clear to me what you mean by

six plots. Did you measure your DV at 6 different time

points?

With kind regards

K.

We noticed the standard deviation of our samples increases along with the mean, which we did not expect. What might this suggest about our data, and does anyone have ideas for how we might follow up on this? Thanks

this could be something as simple as a measurement instrument with a constant procentual error. Is your coefficient of variation constant?

What did you measure? If you are measuring some type of count data, such as the population size, you would model it with a Poisson distribution where the variance = the mean. This would fit what you are seeing.

It would be more interesting if stat4640 showed us the original data.
