Lesson 1.2.1, Aims, research questions and hypotheses: 20 multiple choice questions for the OCR Psychology (H567), Unit 1: Research methods (Component 01), written with Revision Ninja.
Host it live on the board and students join with a game code on their own devices, or revise alone with Free Play. The answers are revealed in the game.
The 20 questions

- Research question
-
What type of hypothesis predicts a difference without stating its specific direction?
- Non-directional
- Null

-
What type of hypothesis predicts no significant difference or relationship between variables?
