FIRST: A researcher decides to test whether having something pleasant to drink (Orange Juice) assists participants in memorizing sentences. Identify the independent and dependent variable in this study and then diagram it. Use the following hypothetical data that support a positive effect for the Orange Juice. Draw a graph that of these hypothetical results.

DATA:

x = 10, 20, 30, 50, 100

y= 500, 550, 570, 680, 900

NEXT:Take the design you constructed above and add the additional independent variable of the sentences being either simple or complex in meaning. Diagram this 2X2 study and list two potential outcomes for the study.

LASTLY: In conducting the study, you obtain results which suggest an interaction between having orange juice and sentence complexity. What does this mean? Create hypothetical results that indicate such an interaction and graph these results.
