Straightforward and informative (not more than 15
words)
Enough to explain your study without going into
too much detail
Examples:
◦ Too little detail: Fast food purchases
◦ Too much detail: Differences in the fast food purchasing
habits of men and women in the last month in Brighton
◦ Just right: Differences in the fast food purchasing habits of
men and women
Independent Variable = the value being
manipulated or changed
Dependent Variable = the observed result that is
dependent on the independent variable

What is the IV and DV in the following titles?
◦ Differences in the fast food purchasing
habits of men and women
◦ The impact of a sensation-seeking
personality trait on alcohol consumption
◦ The effects of aging on reaction time in a
signal detection task

Quick explanation of research area
Summary of relevant past research (and
perhaps its flaws)

4 Hypotheses (2 categorical and 2
continuous)
◦ Aim to predict differences between groups rather
than relationships between variables

Up to 1200 words

Categorical hypotheses:
◦ 2 categorical variables
◦ e.g. “Men prefer to buy fast food at Burger King,
while women prefer to buy fast food at McDonalds”
