Directions (Q. Nos. 98 to 100) : A randomized experiment was done for a year by randomly assigning each participant either to walk for half an hour three times a week or to sit quietly reading a book for half an hour three times a week. The participants’ blood pressure was measured over the year. At the end of the year the change was compared for the two groups.
The two treatments in this study were :
Walking for half an hour three times a week and reading a book for half an hour three times a week
In an experiment, the treatments are the conditions (levels of the explanatory variable) that the researcher assigns to participants; the response variable is what is measured afterwards.
Participants were assigned either to walk for half an hour three times a week or to sit reading a book for half an hour three times a week, so these two activities are the two treatments.
Blood pressure is the response variable, so measuring it is not a treatment, and no group was assigned to do nothing, so a ‘doing nothing’ condition was never part of the design.
Hence, Walking for half an hour three times a week and reading a book for half an hour three times a week.
