research methods two
A team of psychologists is intrested in the possible relationship between level of beleif in telepathy (the
ability to transmit and receive thoughts from one person to another) and sucsess in a telepathy test. after
first carrying out a pilot study, they advertise in the sunday newspaper for people willing to be tested as
part of the study. over the following weeks they test 1000 people in a university laboritory. the p's are
asked to indicate their level of beleif in telepathy. they are then asked to choose one from four alternativde
shapes as the experimenter attempts to transmit the correct shape to them. this is repated 100 times and
the percentage of shapes identified correctly is calculated. the psychologists then correlate the level of
beleif and the number of shapes (out of 100) identified correctly. this produces a correlation coefficient of
+0.7
(a) A suitable hypothesis would be thus : the beleif in telepathy would effect the sucsess of participants on
a telepathy test
(b)
(c) psychologists might have expected that the beleif in telepathy will make a person better on a telepathy
test. This expectation may have effected results obtained as the questionnaire may have been interprated
according to theese beleifs. a way to overcome the problem would be to have many researchers not
directly involved in the experiment interpret the questionnaire
(d) Participants may have pretended to be telepathic in order to please the researcher. the fact that the
experiment was carried out in a university laboritory may have made participants feel the need to impress.
(e) using a pilot study can help to identify anything that may go wrong with the main study. it also helps to
uncover any desgin issues.
(f) one advantage is that you can receive masses of quantitative data. A disadvantage is that it is harm to
determine cause and effect.
(g)
(h)
(i) the right to withdraw was an issues as participants were not told that they could leave the study at any
time. to deal with this issue psychologists could include it in the advertisment saying that P's are allowed
to withdraw at any time and can also withold their data from the finidings if they should feel it nessesary.
(j) +0.4 is stronger than -0.6
(k) .
