Step-by-Step Solution:
Step 1 of 3

What is Statistics  Data collection: is collected by performing statistical experiment o 2 designs  Controlled experiment  Observational studies  Ex. A new drug is discovered. How should an experiment be designed to test its effectiveness o We divide the subjects at random into two groups. One will receive the treatment and the other will not. The results will be compared. o The group that receive treatment is treatment group. o The group who do not receive the treatment is the control group. o The basic method to study the effectiveness of drug will be the method of comparison. o It should be double-blind; doctor don’t know which group the subjects are in and neither do the subjects.  Salk Vaccine Field trial th o Study of polio (world’s most feared disease in 20 century) o Jonas Salk discovered a vaccine in 1950. o A large scale field trial was carried out among 2 million school childre3n from grade 1-3.  Grade 1 and 3 were control groups.  Grade 2 was treated.  Grade 2: 1 million; .5 million declined, .5 million accept  Grade 1 and 3: 1 million  The groups were different size but they don’t have to be because the percent will be used not the actually size; the absolute value.  Not all students should be vaccinated to compare
