Use the descriptiоn оf the fоllowing reseаrch problem to аnswer this аnd the following question. A researcher is interested in examining whether type of meditation causes changes in people's level of happiness. She hypothesizes that: H1: Zen meditation and Tantric meditation improve happiness over no meditation.

And she randomly assigns people to condition (i.e., each participant has an equal likelihood of being in each condition) at the start of the experiment. Using R (randomization to condition), X (administration of treatment), O (observation) notation, pick the experimental design that the researcher might use to investigate these hypotheses. (For more on R, X, O notation, see here--it will open in a new window.)
