A research psychologist generalizes from a particular sample to an entire population. This is an example of

1. statistical inference

2. random sampling

4. stratified sampling

5. descriptive statistics

Option A

Explanation:

The method of how to use data analysis to discern the attributes of an inherent probability distribution is analytical inference. Inferential statistical analysis suggests the characteristics of a community, e. g. through evaluating assumptions and deriving predictions. The observed data set is assumed to be recreated from a greater number of people.

Descriptive statistics can be compared to inferential statistics. Descriptive statistics are concerned exclusively with the characteristics of the observed data, and it is not based on the assumption that the data derive from a greater population.
