ANSWER : INFERENTIAL STATISTICS
Step-by-step explanation: Inferential statistics is a statistical inference, where conclusion is drawn using a set of data that are not gotten from the sample study, but are assumed to relate with the sample study. This type of statistics relies on a probability, that the assumed data used to analyze a sample can be used to study the properties of that sample.
Therefore, for a psychologist to determine the developmental score of a four year old child, without the child participating in the study, the psychologist is most likely to use the scores of other who as participated in the study, to infer as the same with the score of a four year old child.
