Is random sampling or random assignment the more important consideration if the research question is whether students tend to receive higher scores on essays if they are encouraged to submit a draft than if they are not so encouraged

Random assignment

Explanation:

Random sampling and random assignment both implies that selection process is randomized such that each observation has equal chances of being selected.

However, in the case of random sampling, observations to be used in the experiment or research are being randomized. WHILE in random assignment, the observations or participants to be used are already selected, however, the placement of observations into different experimental groups are assigned randomly.

Therefore, in a research to determine whether students tend to receive higher scores on essays if they are encouraged to submit a draft than if they are not so encouraged, a random assignment is required because all participants or observations in the study needs to be adequately selected because it is important that all participants are used to writing essays and not those who detest essays no matter the condition.

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.
