likert estate » likert scale

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( h. ((kept power) OR (net power)) investments series ) OR ( h. likert estate investment fund ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( h. ((kept power) OR (net power)) investments series ) or ( h. likert estate investment fund ))~".
• Adding a wildcard symbol may retrieve word variants: (( h. ((kept power) OR (net power)) investments series ) or ( h. likert estate investment fund ))*.
