sampling error

generalizability

3. What is considered to be the fundamental aspect of probability sampling?

Snowballing

Populations

Samples

Unbiased selection

Random selection

4 _________ statistics as useful for describing characteristics or some phenomenon from either a sample or a population. For instance, we can use these statistics with any data source to describe single variables (univariate) or to describe relationships between multiple variables (multivariate).

internally valid

reliable

descriptive

inferential

quota

Answer 1

1.

Explanatory research is used to check the effect of one variable on another variable, which is the case here.

Option D is the right answer.

2.

A sample is a smaller unit of population. As we can't do the whole experiment with the whole population, we choose a smaller part of it, which is called sample.

Option B is the right answer.

3.

The basic sampling design is simple random sampling. The fundamental aspect of probability sampling is random selection.

Option E is the right answer.

4.

Descriptive statistics describes data (for example, a chart or graph) and inferential statistics allows you to make predictions (“inferences”) from that data.

Here, descriptive statistics is the correct answer.
