Lecture 11, Measurement in Research
We have diﬀerent ways of measuring, depending on the type of study that you are
•direct: the subject knows the researcher is there, and that they are being observed.
In some cases they don’t care, but in other cases like if they’re kids, they do care "
•indirect: you are videotaped, or through something like a one way mirror "
•participant: the researcher is part of the situation. So the professor can be lecturing,
and making observations at the same time "
Physical measurements "
•like weight or height, which can be measured directly "
Cognitive measurements "
•are what you know. This is done through things like tests. "
Aﬀective measurements "
•measuring your feelings "
•diﬃcult to measure, and its usually done through self reporting, by people asking
you how you feel "
Questioning techniques "
•Asking people what they think "
•structured questionnaires: please indicate what you did this weekend "
•unstructured questionnaire: what are you thinking about something "
Delphi technique: "
•A technique for arriving at consensus."
•Assume you have the things that are great about the KINE program, and a list of the
things that aren’t. What you do is take the lists and rank your top 5 and bottom 5. You
then add up how many people voted for each, then select the ones that people voted
for the most "
•Does the study measure what it is supposed to measure, and how conﬁdent are you
in the inferences you make from the results that you have drawn "
Internal validity "
•how correct are you in inferring whatever you are going to infer from the data you
collected. In other words, how good is your experiment "
•Face/logical validity: the test appears correct "
