Answer 1

Answer:

To assess whether intelligence is a single trait or a collection of several distinct abilities, psychologists have made extensive use of factor analysis.

Option: (E)

Explanation:

• In order to delve deep down into the investigation to determine whether intelligence is composed of skills and abilities within oneself or is it a single source in itself that serves the development of abilities, the psychologists had to carry out a multifactor analysis.
• These factors involved the basic elemental foundation blocks of intelligent behavior exhibited by multiple samples (people).
• It was concluded that intelligence is certainly a compound trait of various abilities put to work collectively.
