An experiment is being designed to compare relief from dizziness given by a nbspnew nbspdrug comma a nbspcommonly used nbspdrug, and a placebo. Each subject who suffers from dizziness and volunteers for the study is observed on three separate days, with a different treatment used each day. There are two days between treatments, so that a treatment does not have a carry-over effect for the next treatment assigned. a. What are the blocks in this block design? What is this type of block design called? b. What does it mean if the study is conducted as a double-blind study? c. How can randomization within the blocks be incorporated into the study?

Find the explanation below.

Step-by-step explanation:

1a. Blocks in this experiment include Age, Gender, genetic differences, Individuals with preexisting health challenges, Response to drugs. Blocking is the separation of subjects into homogeneous groups so as to limit nuisance factors. Nuisance factors affect the response of the subjects of the experiment but are not of foremost importance to the experimenter.

1b. The block design is a randomized block design because the experimenter knows that there is a difference between the groups.

2. If the study is conducted as a double-blind study, it means that both the experimenter and the subjects have no knowledge of the group they fall in. That is, whether they are administered the new drug, a commonly used Drug or a placebo. This will reduce bias, a situation in which the subjects react to treatment because of some preconceived ideas they have on how the treatment will affect them.

3. Randomization involves randomly assigning subjects of an experiment to different homogeneous groups. Introducing randomization might mean first classifying the subjects by gender or age into blocks. Members from each block are now randomly assigned to the treatment groups.

i dont know and i dont care for math bc it is a stupied subject
