Test the Graph: Psychology

Move it, then answer

• Drag a yellow grip on the graph, or use the sliders and switches in the panel.
• Dotted lines and hollow dots show where things started. Bars show the new value against a black tick at the start.
• Move something to unlock the four answers.
• A wrong answer tells you why it fails. Try the graph again and pick another.
• Each trip on the map has three hints. A hint points you at the graph and never gives the answer.
• Finish a land to claim it and earn up to three stars for first-try answers. Your journey is saved on this computer.
