Question

Suppose you wanted to estimate the
number of dandelions in a field. It
could take hours to count every single
one, so ecologists use a SAMPLING
technique
A single sample is used to estimate
the size of the overall population.

1. What might cause the estimate to
be wrong with this method?

2. Why would it be difficult to use this
method to estimate the population of fish?​
