In order to maximize the chances that experimental groups represent the population of interest, researchers should conduct random sampling and random group assignment
Explanation:
The terms Random sampling and Random group assignment are greatly different in process of the sample selection. The study related to the determination of how sample participants can be drawn from the population refers to the process of Random sampling. The sample participants are subjected to a treatment by the usage of a random procedure comprises the Random group assignment.
When a researcher wants validate externally then random selection can be used. When a researcher wants to determine the effects of treatment within that group which is known as determination of internal validity then he can opt for Random group assignment.
Answer:
In order to maximize the chances that experimental groups represent the population of interest, researchers should conduct random sampling/random group assignment.
Explanation:
Random selection is a representation of the sample of people for your research from a community. Random assignment is the assigning of the sample that describes various groups or operations in the study.
Reasons:
- Random sampling enables us to get a sample representative of the community.
- Random assignment enables us to make positive that the only distinction among the various treatment combinations is what needs to study.
- Random assignment is crucial for sound empirical design. With adequately large representations, random assignment performs it unlikely that there are methodical variations among the groups.
Thus we can say in order to maximize the chances that experimental groups represent the population of interest, researchers should conduct random sampling/random group assignment.

Answer:
The approximate weight of each paper clip is 0.035 ounce.
Step-by-step explanation:
A container at a paper clip factory holds 2.1*10^3 pounds of paper clips.
= pounds
There are 9.6*10^5 paper clips in the container.
=
Now we get that 960000 paper clips weigh 2100 pounds.
So, each paper clip will weigh = = 0.0021875 pounds
And 1 pound = 16 ounces
0.0021875 pounds = = 0.035 ounce
Hence, the approximate weight of each paper clip is 0.035 ounce.
Then, multiply that number by 16 to get ounces/paperclip.
