Journal Article 2024 12 30 In this paper we establish new inequalities for convex and strongly convex defined on intervals in framework of Steffensen-Popoviciu and Dual Steffensen-Popoviciu measures are introduced. Some inequalities in this setting are also involved. Suitable examples are also involved are given.
