<h2>Answer</h2>

Stratified sampling

<h2>Explanation</h2>

Stratified sampling is a process of dividing members of the population into homogeneous (separate) subgroups before sampling. Then a random sample is drawn from each group. Members in subgroups may not be fix and subgroups are created under specific type.

<h3>Example</h3>

Subgroup:  Sophomore, Junior, Senior classes

This sampling technique increases the precision of sampling by reducing sample size especially when population size is too large.

In cluster sampling, a random subset of population is created and then random sample drawn from it. Members of all subgroups are equal.

In systematic sampling, fixed intervals from the larger population create the subset of population. Members of all subgroups are equal.

Which group’s rights—human participants or nonhuman animals—are the most important to protect? Why?
frez [133]

I personally have to go with nonhumans.


Most of the animals are defenseless, especially when humans fight unfair.

Think about, humans kill lions. But it should be a fair fight, obviously the lion would win. But humans have crafted weapons to harm these creatures a lot of the times for absolute no reason besides greed.

I feel like animals are very defenseless and clueless and humans take advantage to that to the max- sadly.

If you need a longer explanation, I can give more.

Hope this helps!
