© identify the type of experimental design that was used
Give one advantage and one disadvantage of this design
(d) explain why the experiment was designed in such a way that half the p’s saw the positive programme
first and the other half of the p’s saw the negative programme first ?
(e) give one advantage of using the mean?
What does that standard deviation tell us about data
(f) a histogram to show weather the content of a television news programme can influence a persons mood
Participants mood scores
(g)
