Practical 1

1. You are asked by Apple to evaluate the new iPhone particularly in
comparison with three older mobile phones with keypads (let’s call
them the Nokia, Motorola and LG). You are asked to conduct two
experiments
a. one on the usability of the iPhone touchpad in comparison with
b. one on the usability of the iPhone in different environmental
conditions (indoors; outdoors in warm weather; outdoors in cold
weather, so user would want to wear gloves).
(this is the kind of situation in which you could do one study and
test both independent variables, but assume you will do two
separate studies)

For each study state
(i)    what is the independent variable?
(ii)   what would suitable dependent variables be?
(iii)  would you have a control condition, if so what would it be?
(iv)   would you use a between participants, within participants or
matched participants design? Justify your decision.
(v)    How many participants would you need (using the 5 minimum per
condition heuristic)?
(vi)   What would you need to counterbalance?
(vii) What threats to the integrity of the results can you think of?
(viii) Are you satisfied that the design will answer the questions to
Apple’s satisfaction?

2. Take a problem in your own research area (or a research area of
interest) and design an experiment.

(i)     What is the hypothesis you are testing?
(ii)    what is the independent variable?
(iii)   what is/are the dependent variable/s?
(iv)    would you have a control condition, if so what would it be?
(v)     would you use a between participants, within participants or
matched participants design? Justify your decision.
(vi)    How many participants would you need (using the 5 minimum per
condition heuristic)?
(vii)   What would you need to counterbalance?
(viii)   What threats to the integrity of the results can you think of?
(ix)     Are you satisfied that the design will provide a good test of the
hypothesis?
