The type of sampling method in which a sample frame is <em>divided into groups,</em> which are highly similar to the other
- <u>Simple random sampling.</u>
<u />
According to the given question, we are asked to show the name which is given to the type of sampling method in which a sample frame is divided into groups, which are highly similar to the other.
As a result of this, when a sample frame is divided into groups which are very similar to each other, then this is a simple random sampling.
In this method, we can see that there are different types of <em>random sampling techniques</em> which includes:
- <u>Simple random sampling</u>
- <u>Stratified random sampling</u>
- <u>Cluster random sampling</u>
- <u>Systematic random sampling</u>
Therefore, the correct answer is Simple random sampling.

The error
Going through the steps, we can see that there are no mistakes in any of the step.
However, the conclusion that there are infinitely many solutions is wrong
because the solution actually has no solutions.
16x + 9 = 9y-2x Add 2x to both sides
18x + 9 = 9y Divide both sides by 9
2x + 1 = y Switch the sides to make it easier to read
y = 2x + 1
