Question

The following summary table corresponds to a hypothetical experiment in which subjects must complete a mental task at five levels of difficulty and with three different levels of reward. Much of the table has deliberately been left blank, but all of the missing entries can be found by using the information in the previous sentence and the information in the table (hint: start with the df column – it will make your life a lot easier!):

source	SS	Df	MS	F
difficulty	100	?	?	?
reward	150	?	?	?
interaction	?	?	5	?
Within	?	90	?
Total	1190
